Tips & Ideas

Use "mystic" style for mysterious alien worlds and "harsh" style for hostile or barren planets.
Generate planet names in batches to populate an entire star system with consistent naming.
Shorter names work well for frequently visited planets; longer names suit distant or legendary worlds.
Pair planet names with designations like "_____ Prime" or "_____ VII" for a sci-fi feel.

Frequently Asked Questions

Are these planet names suitable for sci-fi settings?

Yes. This generator produces names with a cosmic, astronomical quality that works for both science fiction and cosmic fantasy settings. The names avoid real planet names and popular fictional ones.

How do planet names differ from world names?

Planet names have a more cosmic and astronomical feel — they sound like they belong in a star chart. World names feel more mythological and setting-like, suitable for naming an entire campaign or universe.
