Are these names from any published fiction?

No. The names are original, built from short syllable and word lists designed to sound like planet names, not pulled from any book, game, or franchise. They are safe to use in your own setting.

What is the difference between the naming styles?

Alien names combine invented syllables for a harsher, non-human sound. Classical names mix Latin and Greek-style roots for a more familiar, mythological feel. Gas Giant names lean toward short, heavy-sounding designations that fit large gaseous worlds.

Can I generate more than one name at a time?

Yes. Use the count selector to generate up to 20 names in a single batch, then copy the whole list or just the ones you like.

Does this tool store or send my generated names anywhere?

No. Every name is generated in your browser with no network request, and nothing is saved once you leave the page.

Can I use these names commercially?

Yes. The names are generated from generic syllable combinations with no ownership claim, so you are free to use them in a published game, book, or product.
