Alien Planet Name Generator

Science fiction names its planets in four recognizable ways, and a convincing alien world usually fits one of them. The first is the alien-language name: a word that belongs to whoever lives there, with a phonology that feels foreign but pronounceable, like Zorvath, Xenthara, Ka'Tesh or Qo'nath. Apostrophes, doubled consonants and rare letters (x, q, z, kh) signal otherness; a clean vowel at the end keeps it sayable.

The second is the survey designation, which is how humans would actually label a new world: a star name or catalog number plus a Roman numeral or lowercase letter, such as Epsilon Veldra III, Tau Oriel b or Keplan 88b. The third is the colony name, where settlers reach for something hopeful, homesick or blunt: New Tharsis, Coldharbor, Halcyon Reach, Petrov's Folly, Landfall. The fourth borrows from myth and lost lands (Hyperborea, Xibalba, Breidablik), a trick used by many space operas for planets that should feel ancient.

This generator mixes all four, plus descriptive names like Bloodmoon and Saltglass and a few epithet-style worlds such as Drowned Arkady or Eye of Thessa. Match the style to who named the planet in your story, and it will sound like it has a history before your characters arrive.
