How it works

Naming every planet of an imaginary solar system by hand can quickly become tedious. This tool combines evocative syllables, astronomical catalog-style formats (in the manner of real exoplanets like Kepler or Gliese), and poetic constructions to quickly suggest a list of believable, varied names.

Which style should I choose for a realistic science-fiction universe?

The "catalog" style mimics the real scientific nomenclature of exoplanets and suits a hard, realistic universe; the "syllabic" or "poetic" style sounds more exotic and suits a space opera or a fantasy role-playing game better, where each world has its own cultural identity.

Can I also get a brief description of each planet?

Yes, enable the "Add a short description" option to attach a descriptor (icy, volcanic, oceanic...) to each generated name, a quick way to sketch out a world's atmosphere before developing it further in your story.
