How the Planet Name Generator Works
Each name fuses a root and an ending drawn from pools we wrote after reading real exoplanet catalogs. Roughly a third of the endings carry designations — Prime, Roman numerals, Minor — so some results arrive pre-stamped by an imaginary survey office, while others come out clean for worlds nobody has mapped yet.
The 100 curated planets below add the layer a bare name cannot: orbit, climate, and the one economic or political fact that makes a world worth visiting. We wrote each line so a game master can drop the planet into a sector map mid-session and improvise the rest from that single sentence.
Planet Naming Conventions
Science fiction planet naming runs on two registers. The bureaucratic register uses designations — position numerals, Prime for capitals, Minor for lesser twins — and signals a mapped, administered galaxy. The vernacular register is what settlers actually say: Landing, Drift, Anchorage, or just a shortened root. A setting that uses only one register feels thin; the friction between the two is where colony history lives.
Phonetics carry climate. We tested this across the curated list: crisp consonant clusters (Vosk, Tyxis, Kryllos) read as cold, thin-aired, mineral; long vowels and liquids (Thessaline, Cerulyne, Mervandia) read as warm, wet, habitable. Match the sound to the biosphere and readers will picture the world before you describe it — fight the sound and every mention works against you.

Tips for Choosing a Planet Name
- Reserve Prime for one world per system; two Primes on a map is a continuity bug players will find.
- Give inhabited worlds a designation and a nickname — the gap between them is instant lore.
- Match sound to climate: hard clusters for ice and rock, open vowels for oceans and jungles.
- Keep numerals honest — Oskarion IV should really be the fourth orbit, because someone will check.
- Name the system after the star and let planets inherit the root; a Veyra system with Veyra Prime and Veyrun Halo reads as real astronomy.
Frequently Asked Questions
How does the planet name generator work?
It joins one of 42 invented stellar roots with one of 42 endings, many carrying survey designations like Prime, IV or Minor — over 1,700 combinations such as Veyra Prime and Oskarion IV. We modeled the sound on real exoplanet catalogs, then swapped the astronomers' letters for names a crew would actually say.
What do Prime, IV and Minor mean in a planet name?
They are survey conventions: Prime marks the first or capital world of a system, Roman numerals count position from the star, and Minor or Major distinguish sibling bodies. Using them instantly implies a mapped, bureaucratic galaxy — skip them for lost or alien worlds.
Should a sci-fi planet have one name or several?
Several, if anyone lives there. A catalog designation, a settler name, and sometimes a native or slang name — the gap between them is story. In our own campaigns the moment a character says the old name instead of the official one, the politics arrive for free.
Can I use these planet names in my book or game?
Yes — every generated and curated name here is original, so you can use them freely in fiction, tabletop campaigns and games; just search a favorite before commercial use to make sure it does not collide with a published franchise or a real exoplanet's popular name.
How do I make a planet name hint at the world itself?
Lean on temperature and texture. Hard, short names like Tyxis or Vosk read as rock and ice; liquid ones like Thessaline or Cerulyne read as ocean and jungle. We sorted the curated list this way — pick the entry whose lore matches your world and the name does half your description.
