Planet Name Generator
Sci-fi planets need cosmic gravitas - Vexar Prime, Yelora-V, Aurinox-IX, Belendrak Beta. Our planet generator combines cosmic-feeling roots (Vexar, Yelora, Aurinox, Drakon, Helios, Iridos, Pyrandus) with sci-fi suffixes: Roman numerals, Greek letters, Prime/Major/Minor designations, and bare unsuffixed names.
Example output: Vexar Prime · Yelora-V · Aurinox-IX · Belendrak Beta
Frequently asked questions
›Why Roman numerals for planets?
Astronomy convention. Star systems often number their planets with Roman numerals (Mercury = Sol I, Venus = Sol II, Earth = Sol III). Sci-fi inherits this. "Yelora-V" reads as the fifth planet of the Yelora system.
›How do I name a binary star system’s planets?
Use the Greek-letter suffixes (Beta, Gamma, Theta) for binary or multi-star systems. "Belendrak Beta" suggests the second planet around the second star. Or pair Roman numerals with Greek letters: Belendrak-VI Beta.
›Can these work for fantasy worlds with cosmic naming?
Yes - high fantasy with mage-astronomers (Earthsea, Witcher) often borrows cosmic naming for celestial bodies. Strip the Roman/Greek suffixes and use bare cosmic roots (Vexar, Helios, Drakon) for fantasy planets or moons.
