Aldea11 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.11 When the Bough Breaks
Aldebaran III12 Long-time Federation member planet on which Janet and Theordore Wallace experimented on plants using carbohydrate compounds to slow their ageing.12

In 2381 the Aldebaran system was one of those attacked by the Borg. The system was saved when the Talarian Third Fleet halted the Borg attack. The fleet was largely destroyed in the battle.2

Alpha 11714 Class M planet which becomes exceptionally cold during the night-time; Kirk was split into two halves by a transporter accident when beaming up from here. As a result a landing party was stranded on the planet by a hold on using the transporter system, and almost froze to death.14 The Enemy Within
Alpha 44115 A planetoid in the Badlands, Alpha 441 was the site of a Maquis munitions base. In 2370 it was the target of an attack by the Cardassian Dreadnought. Although the missile penetrated the defences, it failed to detonate thanks to an obsolete kinetic detonator.15 Dreadnought
Alpha Carinae II16 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.16 The Ultimate Computer

Alpha V23 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.23 Charlie X
Altair III24 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.24 Encounter at Farpoint
Altair IV25 The fourth planet in the heavily populated Altair system. The planet is the home of Doctor Henri Roget, winner of the 2371 Carrington Award.25 Prophet Motive

The event was expected to send political ripples all the way to the Klingon Empire. However, Captain Kirk diverted the ship to Vulcan for Spock's Pon Farr.26 Altair VI was also mentioned in Starfleet Academy's Kobayashi Maru simulation as the departure port of the damaged vessel which the ship was expected to rescue.27 Amok Time
Altamid28 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.28

Balthazar came to master much of this technology, transforming himself into a local warlord and pirate.28
Star Trek Beyond
Altec29 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.

Alture VII30 A planet which was the setting for a meditation holoprogram.30 Birthright, Part 1
Amleth Prime31 Cardassian planet located inside an emission nebula. The presence of the nebula renders cloaking devices ineffectual, making it much more difficult to attack the Cardassian military facilities located on the planet.31 Return to Grace
Amusement Park Planet32 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.32 Shore Leave
Andevian II31 Planet with at least four moons. Andevian II is a popular holiday destination.31 Return to Grace
Andor33 Gas giant planet. One of the moons, Andoria, is the home of the Andorian people.33 The Aenar
Andoria25 Home of the Andorian people25 Andoria is a planet-sized moon orbiting the ringed gas giant Andor. It has a very low average surface temperature, such that only on relatively rare occasions can liquid water be found on the surface.33

Andor was one of the systems attacked by the Borg in their invasion of the Alpha Quadrant in 2381.The planet suffered badly in the invasion, but was not destroyed.2
Prophet Motive
Andros III34 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. In the Cards

Angosia III36 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.36 The Hunted
Antede III37 Home planet of the Antedeans, and intelligent species of piscines. In 2365 the Enterprise-D transported two Antedean ambassadors from the planet to Pacifica for a conference which was expected to confer Federation membership on the planet.37 Manhunt

AR-55840 Planet which was the site of a major Dominion Communications relay. AR-558 was the scene of bitter ground fighting after the Allied invasion of Cardassian space, with little in the way of reinforcements arriving for the hard pressed Federation forces there.

Arakis Prime41 Delta Quadrant planet where the EMH went on one of his first away missions. It has crystal glaciers and a magnesium vapour atmosphere. The planet is apparently named for Arrakis, the central planet in Frank Herbert's Dune series. It's possible that Voyager's crew named that planet and that whoever did was a fan of Frank Herbert.41 One Small Step
Archanis IV42 Planet claimed by the Klingons42 Broken Link
Archer IV43 Planet the Enterprise-D headed for after encountering an anomaly in 2366.43 Archer IV was first discovered by the NX-01 in 2151.

By the 2260s the population of Archer IV numbered 700 million.45 Yesterday's Enterprise
Archer's Planet46 The second planet to be named after famed explorer captain Jonathan Archer, Archer's planet is in the Gamma Trianguli sector.47 In A Mirror, Darkly Part II
