Sci-Fi Planet Name Generator

Science fiction has settled into a few reliable ways of naming planets, and each one tells the reader something about the world's history. Invented proper nouns (Veridane, Korrath, Nuvaris) suggest a native population or a long-settled culture. Survey designations built from a star name plus a Roman numeral or lowercase letter (Epsilon Marrow IV, Zeta Halloran b, KX-1138) signal a frontier world that humans catalogued before anyone lived there. Colony names are the most emotional: settlers name worlds for home (New Carthage, New Kyoto), for hope (Providence, Newhope, Landfall) or for what the place did to them (Widow's Reach, Fort Dismay, Last Light).

Two more styles round out the genre. Mythic and classical names (Elysium, Tartarus, Lyonesse, Hyperion) give a world instant gravity and are a favorite of space opera, and epithet names such as The Cinder World, Eye of Tessaly or Drowned Carrow work as nicknames that the crew uses instead of the official designation.

This generator covers all five registers so you can build a believable star chart: official catalog names for the survey office, local names for the people who live there, and slang for the pilots who fly between them. Pair a designation with a common name and the planet already feels discovered, settled and argued over.
