In compiling the list I stuck strictly to those places establispag as existing planets. This has led to a few judgement calls - for instance in Star Trek II Khan says he will chase Kirk "round the moons of Nibea...", but given the context (a modified Moby Dick quote) I think there's a strong possibility that Nibea is fictional so it isn't included. I was tempted to add some references which can be inferred from species names - i.e. in Voyager's "Retrospect" we meet the Entharans, a species which trades heavily with other races. This is generally a fairly conclusive proof that their home planet would be called Enthara. However, we do know that there are species in Trek whose name does not in fact come from their planet - Humans don't come from the planet Huma! So I have not made assumptions like this.
These kinds of decisions have led to about 70 candidates being missed out from this list, and many of these are likely to be actual planets. But I did want this list to be as canonical as is possible.
I've always found Trek species and planet naming conventions to be a little disappointing. It's a shame that the writers seem so locked into naming almost every species after their planet; worse still, there are times when both the star, planet, and species all have the same name. Even the Bajorans come from a Planet called Bajor which orbits the star Bajor! Rather like having Humans being called Solians from the planet Sol in the Sol system.
Any corrections or additions to this list will be gratefully appreciated, but please stick to canonical sources only - by which I mean the aforementioned films and live action episodes. No TAS, Tech Manuals, etc please. If you want your update to be speedily incorporated I need a planet name, the episode it comes from, and if possible a rough idea of where it's mentioned in the episode.

The Vulcans became concerned that the settlement was a military outpost and claimed the planet in 2097, removing the colonists by force. It remained uninhabited until the Andorians landed a small force in 2152, prompting further hostilities. Captain Archer was able to negotiate a cease fire.410 | Cease Fire |

The planet was considered to be very cosmopolitan at the time, with visitors from many different species.435 Tourism was one of the major industries on Risa, with the Vulcan database listing more than two hundred registered Nuvian masseuses on the planet374 and attractions including subterranean gardens filled with luminescent plants, steam pools435, and a water recreation park.436 In 2135 T'Pol tracked a two Vulcan fugitives to Risa. She killed one, but the other escaped.118 In the 24th century, Commander Riker was very fond of the planet and managed to convince Captain Picard to holiday there.114 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.401 Geordi La Forge was on his way to Risa in 2367 when he was abducted by Romulans.357 Starfleet intelligence believed that Federation Ambassador Krajensky was replaced by a Founder infiltrator whilst visiting Risa in 2371196 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.317 In 2375 Grand Nagus Zek and Ishka retired on the planet.168 |
