Generate Star Trek planet names that sound like they belong on a Starfleet star chart: catalog-style worlds like Omicron Ceti III and Gamma Hydra IV, homeworlds like Qo'noS and Ferenginar, Prime worlds, colonies and outposts. Includes hundreds of canon planets alongside original names for fan fiction, Star Trek Adventures and Starfleet-style worldbuilding.

About Star Trek planet names

Star Trek planets follow a handful of naming habits that make them instantly recognisable. The most common is the Federation catalog style: a Greek letter or star name, sometimes a constellation, then a Roman numeral marking the planet's position from its sun. Omicron Ceti III, Gamma Trianguli VI, Ceti Alpha V and Tau Cygna V all work this way, and the numeral matters: a world is usually the third, fourth or fifth planet, where a habitable orbit is plausible, rarely the first or the tenth.

Homeworlds break the pattern and simply carry the name a species uses for itself: Vulcan, Qo'noS, Romulus, Bajor, Ferenginar, Betazed, Andoria, Talax. Klingon, Romulan and Cardassian names keep the phonology of their languages, so apostrophes, hard consonants and doubled vowels all signal who lives there. When a star system has several inhabited planets, the capital is marked with Prime (Cardassia Prime, Tellar Prime, Azati Prime) and the others get numerals.

The rest of the list uses Trek's less formal conventions: colonies named for Earth places or founders (Terra Nova, Sherman's Planet, New Sydney), alphanumeric survey designations for barely charted rocks (Holberg 917G, Kiley 279, AR-558), and single evocative words for Delta Quadrant worlds met once and never again (Sikaris, Quarra, Ocampa). Mix two or three styles across a sector and the map reads like a real star chart.

How to choose Star Trek planet names

  • Match the naming style to who charted the world: Federation survey names get Greek letters and Roman numerals, Klingon worlds keep apostrophes and hard consonants, and Delta Quadrant planets should sound nothing like either.
  • Keep Roman numerals plausible. Class M worlds in canon are almost always II through VII; a habitable Rigel XII or Ktaria VII is the exception that stands out, so use it deliberately.
  • Reserve Prime for the capital of a multi-planet system and give the other worlds numerals (Cardassia Prime, but Cardassia IV for the penal colony).
  • Colonies sound different from homeworlds: a Federation colony is usually New-something, a founder's name or a star plus Colony, while a homeworld is one self-contained word.
  • Steal the canon names freely for background chatter and fan fiction, but give your own plot-critical planet an original name so it will not collide with an established episode.

Frequently asked questions

How are planets named in Star Trek?

Most Federation-charted planets take their star's name plus a Roman numeral showing their orbit, such as Rigel VII or Deneb IV; many stars carry Greek-letter designations like Omicron Ceti or Gamma Hydra. Homeworlds use the native name (Vulcan, Qo'noS, Bajor), system capitals add Prime, and uncharted worlds get survey codes like Holberg 917G.

What does Prime mean in a Star Trek planet name?

Prime marks the principal or capital planet of a system, usually the homeworld of that system's species: Cardassia Prime, Tellar Prime, Ferengi worlds like Kelvas Prime. Secondary planets in the same system are then written with numerals, for example Cardassia IV.

Are these names from the actual shows?

Roughly half are canon worlds drawn from every series, from Talos IV and Organia in the original series through Ba'ku, Ocampa, Xindus, Kaminar and Coppelius in the newer shows. The rest are original names built on the same conventions so they fit alongside canon planets on a sector map.

Why do so many Star Trek planets end in a Roman numeral?

Starfleet labels planets by distance from their star, so a numeral tells a navigator exactly which orbit a world occupies. Writers also used the pattern to make a planet sound catalogued rather than named, which suits worlds no Federation citizen has visited before.
