Random Planet Name Generator

Building a star map for your sci-fi epic or homebrew RPG? Our Random Planet Name Generator uses advanced AI to mint fresh, evocative planet names in seconds—no astronomy degree required. From scientific designations to myth-heavy monikers, every click expands your universe.

Choose a Host Star Type—Red Dwarf, Yellow Main-Sequence, Blue Giant, or even Binary—to steer linguistic cues. Pick a Planet Class such as Terrestrial, Gas Giant, Ice World, or Lava. Adjust the tone: scientific for realistic space sims, mythic for epic space fantasy, alien for the truly otherworldly. Add an optional keyword like “Nova” or “Prime” and toggle Add Designation to append catalog tags like “-III” or “BX-12.” Generate up to 50 names at once and filter by length.

The language model blends Latin, Greek, and modern astrophysics jargon with phonetic patterns from global mythologies. It balances readability and mystery, producing names that fit both NASA press releases and cosmic opera scripts.

Set your parameters, click Generate, and watch a constellation of planet names appear instantly. Bookmark your favorites, regenerate for endless possibilities, and roam our wider toolkit—city names, dragon names, business brands, and more—free, unlimited, and forever AI-powered.
