Name planets the way real ones get named — Vega Prime, Lyra IV, Rigel b — star names with a designation, following the actual IAU exoplanet convention.

How these names are built
Real planets outside the solar system follow a naming rule you can copy exactly: the star's name plus a lowercase letter, in order of discovery — 51 Pegasi b was the first exoplanet found around a Sun-like star, and the b simply means 'first found there'. Science fiction extends the same grammar with ordinals (Vega Prime, Lyra IV) for colonized or catalogued worlds. The result is names that sound astronomically legitimate because they are astronomically correct — a reader cannot tell your Rigel b from a real research paper's. The star layer here draws from the traditional star-name register (Vega, Altair, Rigel — real stars, Bayer designations and all) plus invented stars in the same Latin register, then applies the real designation grammar: lowercase letters, ordinals, or Prime for the capital world.
How the generator works
Every result is rolled from 29 + 16 word banks — 464 combinations — using your browser's random source. Nothing is typed in by hand and nothing is sent anywhere: the whole tool runs on your device.

Frequently Asked Questions
How are real exoplanets named?
Star name plus a lowercase letter in order of discovery: the first planet found around a star gets b (the star itself is a), the next c, and so on. Some get proper names through IAU public campaigns, but the letter system is the default — and this generator uses it exactly.
What does 'Prime' mean in a planet name?
The science-fiction convention for the most important or first-settled world of a system (as in the honourific usage for capital worlds). It reads as political importance; lowercase letters read as astronomical order.
Are Vega, Altair and Rigel real stars?
Yes — traditional star names from Bayer's catalogue. Using real star names with fictional planets is a time-honoured shortcut to plausibility; the invented stars in the bank follow the same Latin register so they blend in.
Can I use these for a whole system?
Roll the same star repeatedly with different designations: Vega Prime, Vega b, Vega c — the shared star name is what makes them read as one system, exactly as real catalogues do.
