DITL Planet No. 858 This panet was the site of a crash-landing by a Federation Runabout in 2371. It was class L, barely habitable. At least some of the local vegetation was poisonous, and the climate tended towards the cold side. [78]
Norellus [79] This is probably but not certainly a planet - Norellus was described as the site of a Deuterium station. [79]
DITL Planet No. 854 This habitable planet was the site of a Dominion attempt to kill Major Kira in 2369. A Founder lured Kira and Odo to the planet, then abducted Kira and impersonated her in an attempt to explore the nature of Odo's relationship with her. The Founders hoped that if Odo believed Kira dead, he would return to the great link. The plan failed. [80]

DITL Planet No. 833 This Delta Quadrant world is the home planet of the Brunali. It lay near a Borg transwarp conduit, and as a result it was a frequent victim of attacks which decimated the population. Voyager visited the world in 2376. [82]
The Wierd Planet [83] This Delta Quadrant world existed in a state of extreme temporal flux as a result of the subspace particle field produced by its tachyon core. The world had Gravimetric readings similar to that of a collapsed dwarf star. It also resembled a quasar in that it had a rate of rotation of approximately fifty eight revolutions per minute. The name was suggested by Naomi Wildman. Her initial suggestion was "The Weird Planet Where Time Moved Very Fast And So Did The People Who Lived There". Seven of Nine suggested a slightly more precise "The Weird Planet Displaced in Time". [83]
DITL Planet No. 806 This Delta Quadrant planet was the location of an outpost of the Mikhal Travellers. Voyager visited the world 2373. [84]
DITL Planet No. 795 This Delta Quadrant planet was home to the Mokra Order. Janeway was briefly stranded here in 2372 whilst trying to purchase tellerium for Voyager's engines. [85]

DITL Planet No. 807 This Delta Quadrant planet was a Nezu colony. Voyager lent assistance when the planet came under attack in 2373. [86]
DITL Planet No. 800 This Delta Quadrant planet is the home world of the Kohl people. The planet underwent a solar flare in 2353 which caused a significant climate shift and bathed the planet in radiation, threatening the Kohl. Although they took refuge in suspended animation, most of the Kohl did not survive. Voyager encountered the few surviving Kohl still locked into suspended animation when it visited the planet in 2372. [87]
DITL Planet No. 823 This Delta Quadrant planet is the home of the Dream Species which VOyager encountered in 2375. [88]
DITL Planet No. 813 This Delta Quadrant planet is the Garenor home world. In soem timelines created by the Krenim Timeship, this world was erased from history. [89]
DITL Planet No. 875 This Class M planet was near the edge of the galaxy, being approximately an hour from the galactic energy barrier at Warp 11. In 2268 a Kelvan ship was destroyed near the planet as it crossed the energy barrier. Several survivors from the ship landed on the planet where they subsequently captured a landing party from the USS Enterprise, and then the ship itself. [90]
Altair III [91] Third planet in the well populated Altair system. William Riker once refused to allow Captain De Soto to beam down to this planet, stating that it was too dangerous to him. The controversial action prompted Captain Picard to offer Riker the First Officer position on the Enterprise-D. [91]
Amusement Park Planet [92] The world was used as a huge amusement park by an advanced alien species. Although the surface gave the appearance of an undeveloped world inhabited only by plantlife, beneath the ground were gigantic and highly advanced factories. Sensors could detect the thoughts of those on the surface, determining their innermost desire and then fabricating whatever was necessary for them to live it out. Even perfect simulations of real people could be created for visitors to interact with. The Enterprise crew visited the planet in 2267 for some rest and recreation, believing it to be uninhabited. They were initially perplexed by their experiences there but once the caretaker of the world explained the situation to them, the crew were able to have a highly enjoyable time. [92]
Tau Alpha C [93] The Traveller's home world. [93]
Beta III [94] The third planet of the C-111 system, Beta III was home to a pre-warp humanoid species. Approximately 6,000 years ago the planet was wracked by civil wars, so much so that a leader named Landru created a highly sophisticated computer system to solve the problem. The computer was capable of "absorbing" a person, radically altering their personality in order to make them dedicated to peaceful coexistence. Unfortunately this had the effect of stifling their natural emotions to such an extent that some form of outlet was needed; the computer solved this by allowing periodic release during "festivals", in which the population was encouraged to run riot. In 2167 the USS Enterprise visited the planet; Captain Kirk determined that the computer, which had also dubbed itself Landru, was stifling the society rather than continuing it. He destroyed the computer, leaving some sociologists to assist the population in forming a society of their own. [94]
Veridian III [95] The third planet in the Veridian system. Veridian II was a Class M world but did not have a sentient native population. Dr Tolian Soren set up his Trilithium weapon here in 2371, intending to use it to destroy the Veridian star and so alter the course of the nexus, allowing him to enter it. The plan succeeded, destroying Veridian II and all the other planets in the system. Fortunately Captain Picard and Admiral Kirk were able to travel back in time and prevent Soren from launching his weapon, moving those events into an alternate timeline. Captain Kirk was killed in the effort, and was buried in a stone cairn on a mountaintop on the planet.

The Enterprise-D engaged in battle with a Klingon Bird of Prey in orbit of Veridian system, leading to the loss of the ship. The saucer section crashlanded on Veridian III. The bulk of the crew survived and were subsequently rescued. [95]
Ramatis III [96] The third planet in the Ramatis system. [96]

In 2381 Ramatis III was one of the Alpha Quadrant planets targeted in the Borg attack. The entire population of the planet was wiped out in the attack. [97]
Persephone III [98] The third planet in the Persephone system, an arid Class M planet populated with a pre warp civilisation who called themselves the Deleb. It was located in the Alpha Quadrant at galactic coordinates 3876.5452. It had a rotation period of 24.1 hours and an orbital period of 391 solar days. It had an estimated mass of 5.39440x1024 kilograms and an estimated age of 4.345x109 solar years. It had an atmospheric composition of 79% nitrogen, 19% oxygen, 0.9% argon, 0.7% carbon monoxide and traces of methane and boron. In 2258 it had 0.2% of water vapour. It had a mean surface temperature of 15.3°C.

In 2258 a comet C/2260-Quentin passed by and a significant amount of water vapour was deposited into the atmosphere. This resulted in improved conditions on the planet. [98]
Finibus III [99] The third planet in the Finibus system. It is a class M planet with a rotation time of 23.5 hours, an orbital period of 346 solar days. It had an estimated mass of 4.93532x1024 kilograms, and estimated age of 4.7x109 solar years. Its atmosphere consisted of 77% nitrogen, 21% oxygen, 1.2% carbon dioxide, 0.6% nitrous oxide and trace amounts of methane and neon. It had a mean surface temperature of 14.9°C. It was located at galactic cordinates 2721.4369. [99]

In 2258 it was due to have a new air filtration system delivered, without which it would have an unbreathable atmosphere within weeks. Unfortunately, when the Enterprise arrived the colony had been attaked by the Gorn and the vast majority of the colonists disappeared. The USS Enterprise rescued those remaining but was involved in a battle that nearly destroyed it. [99]
Jinoteur III [100] The third of the five planets of the Jinoteur system. Jinoteur IV was not inhabited, although there were signs that it had been in the past. [100] The planet has two moons. [101]
Veridian VI [95] The sixth and outermost planet in the Veridian system. Veridian VI was uninhabited. There were two moons orbiting the planet along with a ring system. On the alternate timeline created by Dr. Soren's destruction of the Veridian sun, Veridian VI and the other planets in the system were destroyed. [95]
Entelior IV [97] The site of a Federation colony. In 2381 Entelior IV was one of the Alpha Quadrant planets targeted in the Borg attack. The colony was destroyed. [97]
Archer's Planet [102] The second planet to be named after famed explorer captain Jonathan Archer, Archer's planet is in the Gamma Trianguli sector. [103]
Veridian II [95] The second planet in the Veridian system. Veridian II was uninhabited. There were two moons orbiting the planet along with a ring system.

Fenris [36] The planet Fenris, home of the Fenris Rangers. [36]
Aldea [105] The planet Aldea was long thought to by mythical, until it revealed itself to the Enterprise-D in 2364. Prior to this it had been hidden behind a cloaking device and shield system. The operation of these devices had destroyed the planet's ozone layer, flooding the surface with ultra violet light which threatened extinction for the Aldeans. The Enterprise-D crew were able to reseed the layer, ending the problem. However, for the solution to remain effective the Aldeans were unable to use the shield or cloak any further, leaving Aldea visible to outsiders. [105]
Xindus [106] The original homeworld of the Xindi, Xindus was destroyed in a civil war between the various subspecies. The Xindi-Avians were rendered extinct in the destruction, prompting the creation of the Xindi ruling council. [107] The NX-01 visited the remains of Xindus in 2153. [53]
Kurill Prime [108] The original home world of the Vorta [108]

DITL Planet No. 772 The Mercenary vessel infiltrated by Captain Picard took refuge at this planet in the Hyralan Sector in 2370. [119]
DITL Planet No. 763 The Loque'eque home planet. This world was visited by the NX-01 in 2153, despite being quarantined by Tret's people. [120]
DITL Planet No. 791 The Koinonian home world. Long thought to be deserted after an ancient multi-generational war, the planet was still dangerous as some weapons were left remaining on the surface. Dr Aster of the Enterprise-D was killed by one of these weapons whilst surveying the planet in 2366. [121]
Elas [122] The inner planet of the Tellun star system, Elas was home to the Elasian civilisation. [122]

Sauria [124] The home planet of the Saurian species. Sauria had a gravity 20% greater than Earths, with a hot climate which produced intense weather activity on the surface. Widespread volcanism spewed toxic gases into the atmosphere. Most life on the planet was nocturnal. [124]
Nausicaa [97] The home planet of the Nausicaan species. [125]

In 2381 Nausicaa was one of the Alpha Quadrant planets targeted in the Borg attack. The planet was devastated in the attack. [97]
Droplet [126] The fourth planet of the UFC 86783 system - named as New Kaferia by the Stellar Cartography department on the USS Titan since the star was very similar to Kaferia’s star Tau Ceti - Droplet was a Léger-type ocean planet. It was Class O, subclass L1. It had a lower density than Earth but was larger, giving it about three times the total mass. Nearly half of that mass was water ice. [126]

Droplet had a metal core thirty seven hundred kilometres deep, surrounded by nearly three thousand kilometres of silicate rock. Above that was a mantle of high-pressure allotropic ice over four thousand kilometres deep. Above the ice was an ocean of liquid water some ninety kilometres deep. [126]

The planet was in an unusually wide orbit around the sun, but had a tropical climate due to the considerable greenhouse in the atmosphere combined with convection currents in the oceans which brought heat up from the bottom. [126]

Unusually for such worlds, Droplet was inhabited by a variety of life forms including higher-order life. Although there was no solid land, the surface was dotted with floating islands composed of a coral-like substance created by living beings. [126]

The USS Titan discovered Droplet in 2381, the ship's first stop on the exploratory mission which it resumed after the Borg crisis earlier that year. [126]
Veridian IV [95] The fourth planet in the Veridian system. Veridian IV was home to a pre-industrial civilisation of some 230 million. There were two moons orbiting the planet. In the alternate timeline created by Dr. Soren's destruction of the Veridian sun, Veridian IV and the other planets in the system were destroyed. [95]
Altair IV [127] The fourth planet in the heavily populated Altair system. The planet is the home of Doctor Henri Roget, winner of the 2371 Carrington Award. [127]
Kessik IV [128] The fourth planet in its system and site of a Federation colony, Kessik IV was the home world of B'Elanna Torres. She and her mother Miral were the only Klingons on the planet during her childhood. [128] Her father John Torres visited Kessik IV in 2378. He was surprised at the changes that had been made to their old house there. [129]

Kessik IV was originally colonised in 2264 by the crew of the mining ship Epimetheus. They chose the planet because it contained significant deposits of dilithium. In 2265, Commodore Diego Reyes and Ambassador Jetanien attempted to use the principle of eminent domain in order to seize the dilithium mines, but the Starfleet JAG office dismissed the request. [130]

Orion gangster Ganz had Cervantes Quinn deliver an illicit cargo to Kessik IV, with an understanding that the recipients would kill him when he delivered. Quinn landed in Anzarosh, a town which served as Kessik IV’s spaceport. It was, in his opinion, a shabby place, and one of the most depressing locations he had ever visited. Quinn managed to evade the trap and return to Starbase Vanguard, which somewhat impressed Ganz. [130]
Jinoteur IV [100] The fourth of the five planets of the Jinoteur system. [100] Jinoteur IV has three moons [101], one of which was the source of the mysterious signal which disrupted some of Starbase Vanguard's systems during the final stages of the station's construction. Like all the moons in the system, it orbited in such a way that one hemisphere always faced the star, whilst the moon itself never came between the star and the planet. [100]

Jinoteur I [100] The first of the five planets of the Jinoteur system. Jinoteur I had two moons, which, like all moons in the system, were in orbits such that they never came between the planet and the system's star. They also exhibited rotation in such a way that one hemisphere always faced away from the center of the system. Artificial structures stood on those outward facing hemispheres. Jinoteur I was uninhabited. [100]
Sarpedion V [132] The fifth planet of the Sarpedion planetary system, located within Cardassian space. Sarpedion V was the headquarters of the Cardassian Twelfth Order during the Dominion war. As such, it was considered to be one of the most heavily fortified locations in the entire Cardassian Union. [132]

In 2375, Chancellor Gowron planned a direct assault on Sarpedion V. He ordered General Martok to lead the attack with a force of fifteen Vorcha-class cruisers, a force level that Gowron thought would 'barely scratch' the defences. [132]

This order led Worf to accuse Gowron of reckless disregard for his men. The two fought, and Worf killed Gowron. Worf declined the Chancellorship, placing Martok in the leadership position in his place. The attack was thus never carried out. [132]
Veridian V [95] The fifth planet in the Veridian system. Veridian V was uninhabited. There was one moon orbiting the planet. On the alternate timeline created by Dr. Soren's destruction of the Veridian sun, Veridian V and the other planets in the system were destroyed. [95]

By the 2340s, Khitomer was a Klingon world, the site of a colony. It was attacked by the Romulans in 2346. Thanks to the betrayal of the Duras family the attack was a complete success, resulting in the massacre of 4,000 colonists. [177] The House of Mogh was almost destroyed in the attack, though the infant Worf was rescued by a Starfleet officer whose ship responded to the attack. [178]

Other Klingons were captured in the attack, and kept in Romulan captivity for decades afterwards. [179]

In 2381 Khitomer was one of the Alpha Quadrant planets targeted in the Borg attack. The USS Ranger managed to defeat the first Borg attack, but not the second, the planet was completely devastated in the attack [97]

Only slightly larger than Earth's moon, the planet was originally class D until it was terraformed by the Andorians after they colonised it in 2052. The Vulcans became concerned that the settlement was a military outpost and claimed the planet in 2097, removing the colonists by force.

In spite of months of gruelling battle with the Jem'Hadar and heavy casualties, Federation troops continued to hold the relay. [237]
Bringloid V [210] Planet which was the site of a Human colony. The colonists set off sometime between 2123 and 2190, intending to establish a low technology world.

The Enterprise-D evacuated the Bringloidi, subsequently resettling them in the nearby Mariposa colony. [210]
Bersallis III [238] Planet which was the site of a Federation colony. Bersallis III suffers a period of massive firestorms every seven years, caused by solar radiation interacting with plasma in the atmosphere. In 2369 the firestorms came a year ahead of schedule and were exceptionally large and fast moving, threatening to overwhelm and destroy the colony and all within it. The Enterprise-D crew managed to erect forcefields to hold back the firestorm whilst the colony was evacuated, saving all 643 people there. Unfortunately eight crewmembers were lost in the effort. [238]

Shantil III [240] Planet which was the location of the island Tanagra. According to Tamarian mythology, the hunters Darmok and Jalad went to the island separately and overcame a dangerous beast there before leaving together, having gained a common understanding of one another. To the Tamarians the phrases 'Darmok and Jalad at Tanagra' and 'Darmok and Jalad on the Ocean' represented the gaining of understanding and friendship through facing a common enemy, and it was this tactic they used to establish communications with the Federation. [240]
DITL Planet No. 872 Planet which was the location of Starbase 11. [241] It is possible that the planet was a moon of a ringed world which could be seen from it's surface. [242]

Angosia III [251] Planet which was applying for Federation membership in 2366. Captain Picard initially considered them good applicants, though Commander Riker regarded the planet as being too "stuffy". During the final stages of the membership application it emerged that during a recent war Angosia had modified some of its citizens to become the perfect soldiers, then imprisoned them rather than try to reverse the process after the war. Picard used the incident to delay membership until the situation had been resolved. [251]
Nigala IV [252] Planet which the Enterprise-D was due to visit after departing Bre'el IV. [252]

Pentarus V [191] Planet which petitioned Picard to mediate a labour dispute [191]
Coridan [256] Planet which petitioned for Federation entry in 2267 [256] Although it is not specifically named as such, the planet featured in Enterprise "Shadows of P'Jem" is apparently the same planet Coridan - though this is not certain since the whole system is called Coridan, so the Trek naming convention would name the planets Coridan I, II, III, IV, etc. [257]

In 2381 Coridan was one of the planets attacked by the Borg in their invasion of the Alpha Quadrant. The planet was badly damaged, but not completely devastated. [97]

Loracus prime [262] Planet which had 5,000 sub-species of termite. I've seen people mistake this for Arrakis prime, and what Cutler says does indeed sound a lot like that. The closed captioning spells it as it is listed here, and listening carefully to the dialogue does confirm this. [262]

This caused a shift in the orbit of Ceti Alpha V that changed what had been a somewhat hospitable climate into one almost impossible to survive in; although the atmosphere remained breathable the surface was barren, and subjected to harsh storms. Only one native life form survived the change, a small and deadly eel. Many of Khan's followers would be killed by the creature and the harsh environment. In 2285 the USS Reliant visited the planet, investigating it as part of Project Genesis. Khan and his followers were able to capture the ship and escape the planet for good. [171]

Quarra [313] Planet located in the Delta Quadrant, the home world of the Quarren species. Quarra is technologically advanced and heavily industrialised, and has a near-insatiable demand for immigrant workers to boost the work force. As a result the Quarren often abduct crewmembers from passing spacecraft and implant false memories in order to convince them they they want to take up residence on the planet. [313]

Romulus [350] Located in Sector Z-6, Romulus is the capital world of the Romulan Empire and home planet of the Romulan species. [350] Romulus was colonised some time after the rise of Surak's philosophy of non-emotionalism on Vulcan in the year 370. Those Vulcans who refused to accept this transition left the planet, founding various settlements on different planets u as they travelled. One group eventually settled on Romulus and founded a new civilisation there. [119] The Romulan civilisation has generally been an aggressive one, and in the 22nd century they fought a war with Earth forces. The war eventually ended with the creation of a neutral zone between the two, a volume of space which both sides were forbidden to send any military forces into. [350] Over the years some transgressions did occur, but very few Federation personnel had ever actually penetrated to Romulus itself even by the 24th century. [364]

Admiral Jarok considered Romulus to be more beautiful than any of the hundred plus worlds he had visited in his military career. He was particularly impressed by the the firefalls of Gath Gal'thong, the Apnex Sea, and the valley of Chula. [320]

In 2368 Federation intelligence located Ambassador Spock on Romulus [77], prompting a covert mission by Captain Picard and Lieutenant Commander Data to the planet. Spock had been working on his own initiative to try and work towards the reunification of the Romulan and Vulcan people. Although Data and Picard did help Spock avert a crisis involving a Romulan attempt to invade Vulcan itself, Spock chose to remain behind on Romulus in order to continue working towards a peaceful reunification. [224]

The planet Remus was located in the same system as Romulus. In 2379 Shinzon murdered the entire Romulan Senate with Thalaron Radiation and requested talks with the Federation. Captain Jean Luc Picard took the Enterprise-E to Romulus itself, the first time a Federation Starship had penetrated the system. The invitation proved to be a trap, but the Enterprise was able to escape. [206]

Spock did make some progress in his efforts to deepen relations between Romulus and the Federation and in 2387, when the planet was threatened by an exploding star, the Romulans approached him to request Federation assistance. Spock personally piloted the vessel that would attempt to neutralise the exploding star with an injection of red matter, but he was too late. Romulus was destroyed with the loss of the entire population. [380]

Deneva was considered to be one of the most beautiful planets in the area, and by the 2260s the population was almost a million, with at least one city of 100,000 people. All contact with the planet was lost in the year 2266, and it was feared that Deneva had fallen victim to an insanity effect which seemed to be progressing through the Galaxy. The USS Enterprise investigated and found that the planet had been infested by the Denevan neural parasites. The ship was able to eliminate the infestation. [289]

Starfleet Commander Atish Khatami's husband Kenji lived in their home on Deneva. [100]

The planet was colonised in 2363. In 2366, the USS Lovell spent an extended period on colony support at the planet. During the same year Jeanne Vinueza took over as the Colony Leader on the planet. One of her first actions was to reject protectorate status from the Federation, claiming independence for the colony. In foregoing Starfleet protection she hoped that the planet would not attract the attentions of the Klingons in the increasing climate of hostility with the Federation. [101]

Gamma Tauri IV was an agricultural colony. It lacked any deposits of dilithium. The planet had a single landmass, an irregular crescent shape that stretched almost two-thirds of the planet's circumference, covering latitudes from the subarctic to subantarctic.

L-S VI [446] An uninhabited Class M planet located about six light years from the Bajoran wormhole. In 2370 a Bajoran science probe picked up some DNA patterns on L-S VI which were very similar to Constable Odo's. The planet was therefore considered as a possible candidate for the original homeworld of the Changelings. The planet suffered a great deal of seismic activity, possibly of volcanic origin. [446]

Ba'ku [300] An M class planet located in the Briar Patch. The planet had a ring system which was loaded with metaphasic radiation; the effect of this was to grant exceptionally long life to the inhabitants of the planet. It was the site of a Ba'ku settlement of about 600 people who had fled their original home world fearing that their species was on a path to self-destruction. The Ba'ku favoured a simple pastoral lifestyle, eschewing most forms of technology. [300]

Eventually a group of Ba'ku became dissilusioned with this mode of living and left the planet, with the result that they began to age normally. They dubbed themselves the Son'a.

Eminiar VII [144] An inhabited planet located in the NGC 321 star cluster. Eminiar colonised the third planet in their system, Vendikar, some time prior to the mid 18th century. Vendikar eventually turned against Eminiar and a war broke out between the two in 1767. The primary means of fighting was the use of long range transporters to materialise fusion bombs over cities; the destruction was so great that both civilisations were threatened with total destruction. As a result, the two societies entered into an agreement to conduct the war via computers; attacks would be carried out mathematically and casualties registered. Those designated as casualties would them report to disintegration machines for disposal. This allowed the war to continue on an permanently sustainable basis. [144]

Eminiar was in an important strategic location with regards to the Federation, and in 2217 the USS Valiant was sent to make contact with the planet. Unfortunately an attack was calculated to have destroyed the ship in orbit, and the Eminians were able to overpower and eliminate the crew in response. The Eminians resisted all further outside contact as strongly as possible, but in 2267 the USS Enterprise was sent to force the issue by making contact over and above their wishes. Again an attack registered the ship as a casualty, but Captain Kirk was able to resist all efforts at immolating him and force a breakdown in the system governing the war. Federation Ambassador Fox offered his assistance in negotiating an end to the conflict. [144]

Lumbu [126] An inhabited planet in the UFC 86659 system, home to a pre-warp civilisation called the Lumbuans. In 2381 Dr Kree abducted Deanna Riker and took her to Lumbu, intending to keep her safe from the Titan's mission until she could give birth to her daughter. [126]

Argus X [255] A planet visited by the USS Enterprise in 2268; a deposit of pure tritanium was discovered here. The landing party was attacked by a dikironium cloud creature. [255]
Draken IV [169] A planet two days away from the Kaleb sector. Draken IV is the location of a Starfleet outpost. In 2369 Romulan dissidents planned to deliver a defecting Vice-Proconsul to Draken IV. [169]
Antos IV [286] A planet once visited by Captain Garth. Garth was taught the art of cellular metamorphosis by the natives, effectively turning him into a shape shifter who could assume the form of others at will. [286]
Danula II [510] A planet on which Picard won the Starfleet academy marathon as a freshman - the only freshman ever to do so. [511]
Thalos VI [340] A planet on which Gaila was once arrested for vagrancy. [340]
Eden [443] A planet long thought mythical, which legend described to be a perfect paradise. Dr. Sevrin became convinced that the planet Eden was real and in 2269 he attempted to reach it by stealing the Federation space cruiser, Aurora, but he and his party were captured by the USS Enterprise. However, he was able to hijack the Starship and make his way to Eden, which lay within Romulan space. Sevrin was a carrier of synthococcus novae, and believed that living on Eden would cure him of the disease completely. However on arrival the planet was found to be lethally poisonous - every single plant was suffused with acid so strong that merely touching it for a few moments produced serious chemical burns. Dr. Sevrin and one of his followers, Adam, were killed attempting to eat fruit on the planet. The others were rescued. [443]
Erilon [100] A planet located within the Taurus Reach. Erilon was Class M in the distant past, but about 27000 years ago the climate shifted radically, changing the planet to a Class P. This left it largely glaciated and devoid of life. [130] However, some microbes were left frozen in the ice. Investigation of these showed that they bore the Taurus meta-gene. A large alien artefact was also located on the planet by the crew of the USS Endeavour. [100]
Palgrenax [100] A planet located within the Taurus Reach, and the home world of the Palgrenai. In galactic terms Palgrenax possessed nothing of military or political value. Mineral ores on the planet were of marginal use for refining or energy generation, and were especially lacking in materials used in Klingon warships. The planet was too remote from Federation colonies and patrol routes to have any real strategic value for the Klingons. Nevertheless, they conquered the planet in the mid 23rd century. [100]

Palgrenax was home to a collection of ancient ruins located on one continent. The Chancellor and High council were interested in the ancient structures, and the Klingon Governor Morqla speculated that this may be the reason behind their conquest. When the Klingon scientists analysing the object managed to activate it, a member of the Shedai species which had constructed the device used it to attack the Klingon occupation forces. A cruiser in orbit bombarded the alien structures in reprisal, prompting the Shedai to destroy the planet. [100]
Delta Vega [380] A planet located near to the Vulcan system. Delta Vega was home to a small Starfleet facility, and several hostile life forms. In the Kelvin timeline, Spock abandoned Kirk on Delta Vega after he judged Kirk to be mutinous. [380]

The planet should not be confused with the Delta Vega located near the edge of the galaxy. [13]
Trelkis Three [116] A planet known for having multi-centric rings. Mayweather always wanted to visit. [116]
Yerad III [100] A planet just outside the bounds of the Taurus Reach. The planet was considered by Cervantes Quinn as a third-rate imitation of Risa or Wrigley’s Pleasure Planet, the home of a large number of resorts, spas and other tourist destinations. It was also known for being the home of a loose collection of nefarious individuals, many of whom used the remote isolated location and large volume of traffic to and from the planet to hide their activities from the authorities. The Yerad system was the home of an outer planet which contained dilithium mines. [100]

In 2265 the Klingon Empire was interested in the Yerad system, both for the dilithium mines and as a possible strategic point for ship servicing operations. The criminal Ganz also had operations on Yerad III. [100]
Levinius V [289] A planet infested by the neural parasites encountered by the USS Enterprise. [289]
Typerias [101] A planet in the Taurus reach. Typerias was a good distance from Starbase 47 (Vanguard); it took the Archer-class scout-ship USS Sagittarius six weeks to reach the station from Typerias, which Commodore Reyes considered to be a good time for the journey. [101]
Mirdonyae V [512] A planet in the Taurus Reach, Mirdonyae V was home to Shedai artefacts. It was held by the Klingons in 2266. [512]
Bryma [395] A planet in the de-militarised zone between the Federation and Cardassia. [395]
Davlos II [101] A planet in the Davlos system, neighbour to Davlos III and thus in close proximity to the Klingon border. The criminal Morikmol was alleged to have ripped a Klingon’s arms completely out of their sockets during a bar fight on the planet. [101]
Raritan IV [399] A planet in the Beta Quadrant visited by Soji Asha and Doctor Agnes Jurati in 2401. [399]
Ajilon Prime [386] A planet in the Arkanus Sector. This world was the site of a battle between Klingon and Federation forces in 2373 during the brief war between the two. Jake Sisko was stranded on the planet during the battle. [386]

In 2381 the Ajilon system was one of those targeted in the Borg attack. [97]
Kelva [90] A planet in the Andromeda galaxy, Kelva is the home world of the Kelvan Empire. Kelva, like the rest of the Andromeda galaxy, is expected to be rendered uninhabitable by high radiation levels within the next 10,000 years. [90]
Altamid [513] A planet in proximity to Starbase Yorktown. In the mid 22nd century the USS Franklin crash-landed on Altamid after being flung into the depths of space by a wormhole. Only three of the crew survived, including Captain Balthazar M. Edison. They discovered the remains of a massive and sophisticated society on the planet, most of it underground. The Altamidians had long since departed the planet, but much of their technology remained intact there. [513]

Balthazar came to master much of this technology, transforming himself into a local warlord and pirate. [513]
Galorndon Core [514] A planet in Federation space, near the Romulan border. Galorndon Core is barely inhabitable - electromagnetic storms frequently rage across the surface, and prolonged exposure to these is dangerous to Humans and Romulans. In 2366 the Enterprise investigated a crashed spacecraft on the planet and found it to be a Romulan vessel. [514] The Enterprise-D again visited the planet in 2368 whilst investigating a Romulan plot to attack Vulcan. [224]
Avenal VII [132] A planet in Cardassian space. Gowron ordered General Martok to launch an attack against this world in the later stages of the Dominion war, despite it being heavily defended. The attack was a disasterous failure. [132]
Risa [66] A planet in a binary star system, famed as one of the great vacation spots of the galaxy. [6] Risa is the site of the most elaborate climate control system in the Federation, as well as seismic regulators. Without this control a lot of the surface area would have been an unpleasant swampland ridden with earthquakes. [66] Risa is approximately 90 light years from Earth, and was first visited by Humans in 2152 when the NX-01 crew took shore leave there. The planet was considered to be very cosmopolitan at the time, with visitors from many different species. [493] Tourism was one of the major industries on Risa, with the Vulcan database listing more than two hundred registered Nuvian masseuses on the planet [439] and attractions including subterranean gardens filled with luminescent plants, steam pools [493], and a water recreation park. [515]

In 2135 T'Pol tracked a two Vulcan fugitives to Risa. She killed one, but the other escaped. [302] In the 24th century, Commander Riker was very fond of the planet and managed to convince Captain Picard to holiday there. [66] Riker met and had a brief romance with a Ktarian woman, Etana Jol, on the planet in 2368, though she subsequently proved to be a covert operative. [391] Geordi La Forge was on his way to Risa in 2367 when he was abducted by Romulans. [516] Starfleet intelligence believed that Federation Ambassador Krajensky was replaced by a Founder infiltrator whilst visiting Risa in 2371 [345] Worf and Jadzia also vacationed on the planet in 2373, where they encountered the New Essentialist, a small political movement that saw Risa as an example of how decadent the Federation had begun. The New Essentialists briefly seized control of the weather and seismic control systems during the visit. [6] In 2375 Grand Nagus Zek and Ishka retired on the planet. [517]

In 2381 Risa was one of the Alpha Quadrant planets targeted in the Borg attack. Large numbers of Risans and guests were evacuated before the Borg arrived but the surface of the planet itself was devastated in the attack, killing every living thing. [97]
DITL Planet No. 766 A planet identical to Earth, home of a group of children are infected by a virus that makes them age incredibly slowly - and die on reaching puberty. [518]
Nimbus III [503] A planet established as "The Planet of Galactic Peace", to build bonds of cooperation between the Federation, Klingons and Romulans by having a planet in the neutral zone whose population comprised of all three species. The effort was considered a failure, as the major powers never followed up on it. Life on Nimbus III was harsh and the standard of living low. In 2285 it was here that Sybok raised his rebellion, capturing the capital city and taking all three ambassadors hostage. [503]
New Vulcan [519] A planet chosen by the Vulcans as a new homeworld after Nero destroyed Vulcan in the alternate timeline he created. [519]
Kelton IV [32] A non-Federation world once visited by Dax, who helped the natives build weather control technology to alleviate a drought. Once the drought ended the natives cut off contact with the Federation. [32]

Altec [318] A member of the Coalition of Madena Along with the neighbouring planet, Straleb. Straleb and Altec were not open enemies, but there was considerable rivalry between their respective heads of government. Much of this friction was eventually resolved when the elader's son and daughter agreed to be married in 2365. [318]
Galvin V [134] A marriage here is only considered successful if offspring result within one year [134]
DITL Planet No. 859 A Maquis planet in the Badlands, Sisko visited this world in 2371 to meet an informant. Unfortunately Eddington held Sisko at gunpoint and announced that he had captured the informant. [324]
Minos [276] A major arms production centre [276]
Krios [516] A Klingon world, the Romulans attempted to convince the Klingons that the Federation was assisting Kriosian rebels to gain independance. [516] Krios was at war with Vault until the Enterprise-D hosted a peace conference in 2368. [521]
Beta Thoridor [97] A Klingon world, Beta Thoridor was one of the planets attacked during the Borg assault on the Alpha Quadrant in 2381. The planet was completely devastated in the attack. [97]
Korvat [68] A Klingon world [97], The Korvat colony was the site of negotiations between the Empire and the Federation in 2289. The Federation was represented by Curzon Dax, whilst the Klingons were represented by Kang and Koloth. The negotiations laid the groundwork for the Khitmoer accords signed several years later. [68]

In 2381 Acamar III was one of the Alpha Quadrant planets targeted in the Borg attack. Most of the planetary population was lost in the attack. [97]
Maranga IV [8] A Klingon world located near the Vodrey Nebula. In 2370 the Enterprise-D attended the Kot'baval festival on Maranga IV so that Worf could introduce his son to Klingon culture. [8]
Beta Lankal [97] A Klingon subject world, Beta Lankal was one of the planets attacked during the Borg assault on the Alpha Quadrant in 2381. The planet was completely devastated in the attack. [97]
Raatooras [118] A Klingon protectorate, the planet was largely abandoned by the Empire in the 2150s and conditions there were poor. The Empire hunted down any refugees who left. [118]
Borzha II [101] A Klingon planet in the Taurus reach. In 2266 the cruiser Zin'za was stationed at Borzha II when it received orders to proceed to the Jinoteur system to capture the USS Sagittarius. Commodore Reyes made a deal with Ganz to have the ship sabotaged to delay the mission whilst he rushed vital parts to the starship. The effort was not successful. [101]
Korinar [100] A Klingon planet close to the Taurus Reach. In 2265 the the Tholians destroyed the Klingon military base on the planet Korinar in retaliation for the Klingon attack on the Tholian military outpost on Zenstala II. [100]
Dorala [100] A Klingon planet close to the Taurus Reach. In 2265 the the Tholians destroyed the Klingon military base on the planet Dorala in retaliation for the Klingon attack on the Tholian military outpost on Zenstala II. [100]
Qu'vat [150] A Klingon colony world near to the Briar patch. Malik planned to attack the colony with bio weapons in order to provoke a war between Earth and the Klingon Empire, but was prevented from doing so by the NX-01. [150] The colony was also the site of a genetic research facility. The Klingons recovered some Augment DNA from the wreckage left after Enterprise destroyed the Augments' ship and used it to develop Klingon Augments. Unfortunately this caused a deadly virus to be created, threatening much of the Klingon Empire. [522] The NX-01 travelled to Qu'Vat after the captured Augment Marab provided the co-ordinates. [523]
Carraya IV [179] A jungle world on the edge of Romulan space, about three hours from Deep Space Nine, site of a secret camp for 73 Klingon survivors of the Khitomer massacre. [179]
Boam II [100] A Human colony world located in the Taurus reach, Boam II was one of the first settlements the Federation placed in the area. In 2265 Cervantes Quinn was granted a contract to ship supplies from Starbase 47 to Boam II. [100]

The case was referred to the Colonial Administration office. [100]
DITL Planet No. 774 A Federation transport crashlanded on this planet, leaving a sole survivor stranded there for many years. The Iyaarans marooned captain Picard there in 2370 as part of an attempt to study the Human concept of love. [434]
M-113 [270] A Federation planet, largely dry and arid. The planet was home to some old ruins, indicating a prior civilisation there. In 2266 a pair of Federation researchers were located on the planet to investigate he ruins. Unknown to the Federation, the planet was also the home of the 'Salt Vampire' species. [270]
Ariannus [230] A Federation planet, considered to be a vital transfer point on the regular space commercial lanes. In 2267 the planet was infected by a bacterial plague which threatened to destroy all life there. The USS Enterprise was able to decontaminate the world and eradicate the infection. [230]
Caleb IV [526] A Federation planet, Caleb IV was attacked by the Klingons in the 23rd century. Kor, commanding the IKS Klothos launched a minor attack and then pulled back, waiting for repairs to commence before launching his full force. [526]
Ingraham B [289] A Federation planet which was struck by Denevan neural parasites in 2265. [289] Terrance Sadler left Starfleet to live on the planet in 2259. [100]
Lya III [320] A Federation planet on which a starbase is located. It is approximately 50 light years from Galorndon Core. [320]
Getheon [130] A Federation planet in the Taurus Reach. In 265 the USS Bombay was scheduled to pick up a team of dilithium prospectors who had been stranded on Getheon when their warp drive failed. The Bombay was unable to complete the mission as she was destroyed in orbit of Ravanar IV by a Tholian fleet. [130]
Jemonon [130] A Federation planet in the Taurus Reach. In 2265 the USS Bombay visited the colony on the planet. [130]
Kilosa [130] A Federation planet in the Taurus Reach. In 2265 the USS Bombay visited the colony on the planet. [130]
Trinay III [130] A Federation outpost in the Taurus reach. In 2265 the cargo department of Starbase 47 (Vanguard) lost a power generator marked for the Trinay III outpost, much to the annoyance of Chief Petty Officer Elizabeth Langlois. [130]
Alonis [97] A Federation member world, Alonis was one of those planets attacked by the Borg in their assault on the Alpha Quadrant in 2381. The planet was spared global devastation, with only a few tens of thousands of casualties in one city. [97]
Delta Rana IV [527] A Federation colony world in the Delta Rana system. In 2366 the colony was destroyed by a Hus'nock warship. The Enterprise-D responded to the distress call. [527]
Lerais II [512] A Federation colony world established in the Taurus reach in 2267. Lerais II was three months from Rigel X at Warp 5. A lush, green world, it was considered a prime candidate for a farming colony. [512]

There were four major landmasses on the planet, and polar caps at both poles. [512]
Alpha V [272] A Federation colony world also known as Earth Colony 5. Alpha V was home to Chales Evans's closest living relatives when he was picked up by the Enterprise in 2266. Although Evans badly wanted to go and live on the planet, Captain Kirk was reluctant to allow him to mix with a civilian population as he feared Charlie may use his unique mental abilities to harm people. [272]
Talagos Prime [130] A Federation colony planet in the Taurus Reach. In 2265 the USS Bombay was going to transport Lieutenant Commander Stutzman to the colony on Talagos Prime so that he could rejoin the USS Endeavour when it arrived there. The Bombay never made the journey, as it was destroyed by the Tholians at Ravanar IV. [130]
Ha'Dara [528] A Class Y planet in the Delta Quadrant, Ha'Dara was selected by the Hirogen prey holograms as a the site of a hologram home planet. They intended to install holographic generators on the surface, allowing a large population of holograms to live there. The Hirogen pursued the escaped holograms to the planet and attempted to hunt them, unsuccessfully. The holograms were ultimately deactivated by Lieutenant Torres and Voyager's EMH. [528]
Alpha Carinae II [529] A Class M world which was used as part of the testing of the M-5 computer system. Home to an intelligent species, it has two continents and a large number of smaller islands. Enterprise crewmember and geologist Carstairs once visited Alpha Carinae II whilst serving in the Merchant Marine. [529]
Qo'noS [176] A Class M planet, Qo’noS - rendered in English as Kronos - is the home world of the Klingon species and capital of the Klingon Empire. [176] The planet was first visited by Humans in 2151 when the crew of the NX-01 took the Klingon operative Klaang back to his people. [117] The co-ordinates of Qo’noS are 43.89.26.05 [519], placing it some 4 days away from Earth at Warp 4.5. [117]

Qo’noS had at least one moon, Praxis, which was a key energy production facility for the Empire during the 23rd century. The Klingons took insufficient safety precautions and over-mined the moon, which resulted in a devastating explosion in 2293. Much of Praxis was destroyed, producing a massive subspace shockwave and severely damaging the planet’s ozone layer and leading to increasing oxygen depletion. The planet was expected to become uninhabitable by 2343 [176], although apparently some way was found to avert this. [530]

Captain Picard visited Qo’noS in 2366 as part of Lieutenant Worf’s attempt to clear his family name. Although Worf accepted discommendation in a political deal to protect the Empire from dissolving into civil war, he and Captain Picard returned to the planet in 2367 to clear his name - and did indeed spark a civil war in the process. [531]

Quark would also visit Qo’noS in 2371 during his brief marriage to the Lady Grilka. [405]

In the Kelvin timeline, Khan Noonien Singh took refuge on Qo’noS after his attack on Starfleet headquarters. He hid in a deserted province of the planet, knowing Starfleet would find it difficult to pursue him there. Admiral Marcus ordered Captain Kirk to bombard the planet with long range torpedoes from the edge of Klingon space in order to kill Khan. Kirk disobeyed orders and instead took a small ship to the planet and captured him. [532]

The planet was divided up into various regions. The Ketha lowlands were the birthplace of Chancellor Martok, an area dominated by farmlands. [526] Grilka was from the Mekro’vak region.  [408] There were also many geographical features of note, including the Lava Caves of No'Mat, the heat of which could produce hallucinogenic effects in Klingons. Worf once experienced a vision of Kahless after spending six days in the caves.  [179] The Hamar Mountains were home to Targs whose shoulders were used in the making of var’Hama candles. [533] The Sea of Gatan was a body of water in which B’Elanna Torres almost drowned as a child. [534] Kang's Summit was a location where Chancellor Martok once hunted Sabre Bear. [535] The Kri'stak Volcano, and the nearby Lake of Lusor were also notable. According to legend Kahless forged the first Bat’leth sword by dipping a lock of his own hair into the lava of the volcano and then cooling it in the lake. [383] The Skral River was noted in a Klingon drinking song which claimed that it once ran red with blood after a battle. [534]

Cities on Qo’noS included Qam-Chee, the site of a famous battle in which the Emperor Kahless and Lady Lukara stood against five hundred warriors - and, later on, jumped on one another ‘like a pack of wild voles’, beginning the greatest romance in Klingon history.  [536]

Quin'lat was another historic city. According to legend a great storm once approached this city; whilst Kahless and others took shelter inside, one Klingon remained to face the storm, determined to make it respect him. The man was killed, and Kahless noted afterwards that his act was more one of foolishness than courage. [408]

Tong Vey was yet another city at which a famous battle took place. Ten thousand warriors, led by the Emperor Sompek, conquered the city after a long siege. Sompek ordered it burned to the ground and every inhabitant killed. Worf enjoyed playing the part of Sompek in a holosuite recreation of the battle, always ending the simulation by giving the order to raze the city. [7]

In 2381 Qo'noS was one of the Alpha Quadrant planets targeted in the Borg attack. The planet was badly damaged in the attack, though not completely devastated. [97]
Nibiru [519] A Class M planet, Nibiru was the home world of the Nibirans, a technologically unsophisticated race of humanoids. In 2259 the USS Enterprise was on a mission to survey the planet when they discovered that it threatened with an environmental catastrophe as a result of a gigantic volcano which was near to eruption. As this would have rendered the Nibirans extinct, Captain Kirk chose to intervene to avert the eruption and prevent the disaster. [519]

Afterwards, Kirk lied about their actions on his report to Starfleet. Spock, however, chose to relate all of the details of their mission. Admiral Marcus responded be relieving Kirk of his command. [519]

Kolarus III [206] A class M planet with a mean orbital radius of 1.2 AU, a mass of 5.972x10^24 kg, and an Oxygen/Nitrogen atmosphere. The planet hosted a pre-warp civilisation, but was nevertheless visited by Captain Picard in 2379 after a positronic signal was detected on the surface. [206]
Tarok [537] A class M moon in Kazon-Olga space. [537]
Adarak [538] A Cardassian world, location of a weapons storage facility and a Cardassian garrison. In 2375 Damar's rebellion launched an attack on the facility after Odo found a weakness in the defences. [538]
Septimus III [539] A Cardassian world, headquarters of the Eleventh Order. In 2375 fifteen Klingon divisions attacked the planet. Weyoun didn't consider it important enough to send reinforcements, and as a result the Klingons obliterated the entire Order, some 500,000 people. [539]
Ventani II [392] A Cardassian world, birthplace of Tret Akleen - the man considered to be the father of the Cardassian Union. [392]
Kelvas V [404] A Cardassian planet, the location of a major repair base. During the Dominion war Breen energy dampening weapons were fitted to Jem'Hadar ships here. A group of Cardassian rebels led a party to capture one of the ships for the Allies. [132] After the Dominion claimed to have killed Damar, rumours spread that he had been spotted on Kelvas V. [517]
Pentath III [7] A Cardassian planet, the infrastructure of this world was largely destroyed during the brief war with the Klingons. After an outbreak of Rudellian plague several relief convoys were sent to the planet; Starfleet provided the USS Defiant to escort one such convoy. [7]
Felton Prime [526] A Cardassian planet, site of a military base. During the Dominion war General Martok destroyed the facility. [526]
Sheva II [526] A Cardassian planet, site of a Jem'Hadar cloning facility. It was one of several targets in General Martok's hit and run raid into Dominion space in 2375. [526]
Rondac III [404] A Cardassian planet, site of a Dominion cloning facility. Damar's rebel forces attacked and destroyed the facility as part of his rebelion against the Dominion. [393] Weyoun speculated that the attack had been planned largely to prevent any more Weyoun clones from being produced. [538]
Simperia [517] A Cardassian planet, site of a base in Damar's rebellion. The base was destroyed by the Dominion in the later stages of the Dominion war. [517]

Trelka V [526] A Cardassian planet, home of a Dominion base with 10,000 troops and an orbiting drydock. The base was the first target of General Martok's hit and run raid in 2375. One of his ships was destroyed in the battle. Martok commented that destroying the base would take half the Ninth Fleet. [526]
Regulak IV [517] A Cardassian planet, home of a base of Damar's resistance movement. The base was one of many destroyed by the Dominion in the later stages of the Dominon war. [517]
Portas V [324] A Breen planet. [324]
Ranuos VI [540] Sonya Gomez thought it would have been a good career move to spend some time working on this planet, as it would give her a chance to do phase work with antimatter. Nevertheless, she turned the post down in hopes of serving aboard the Enterprise-D.
Andros III [541] Planet on which a scientist named Doctor Bathkin suggested that death could be avoided by keeping the cells of the body energized. The theory was not widely known or believed.
