How to use it
Two names
Give each world a catalog name and a local name. It shows who's talking about it.
Build from the hook
Each planet comes with a line of trouble or wonder. That's your first session or chapter.
Name the system
Planets in one system can share a root with numerals: Zeralon I to Zeralon VI.
Example planet names
Planets: KX-6171 b, Moripri, Kesradra, KX-6413 c, Hycor, Ryxinus II, Xathethys VII, Taurapri V.
How planets get their names
Real exoplanets get catalog names: the star's designation plus a letter (b, c, d) in the order they were found. Settlers give them names. A good sci-fi setting uses both: the survey team calls it TR-2210 c, the colonists call it Thalmalia. A Roman numeral after a name usually means the planet's place in its system.
Questions
Is it free?
Yes. Names are put together in your browser, so it's free with no sign-up and no limit.
Are these real planets?
No. Catalog-style names follow the real pattern but the numbers are random.
Can I use these names in my own book or game?
Yes. They're built from word parts rather than copied from a list, so you can use them however you like.
