Frequently Asked Questions

How are real planets named?

In our solar system, planets are named after Roman gods (Mercury, Venus, Mars, Jupiter, Saturn). Exoplanets are usually given catalog designations (Kepler-452b). For fiction, mythological naming gives instant gravitas; invented alien names create authentic otherness.

What makes a good sci-fi planet name?

Great sci-fi planet names balance pronounceability with alien-ness. Names like Arrakis, Pandora, and Coruscant are memorable because they sound exotic but can be said naturally. Avoid names that are too hard to read aloud — your readers have to say them in their head every time.

Can these planet names be used in Dungeons & Dragons or Pathfinder?

Yes — D&D's Spelljammer setting and Pathfinder's Starfinder game both have planets and outer planes that need names. These generators work for any TTRPG setting with a cosmology.
