Space Names

Space Names

Space names have a lovely double life: many are genuine mythological names with centuries of history (Juno, Orion, Phoebe), yet they feel modern, bright and full of possibility. That’s why names like Luna, Nova and Atlas have become so popular for babies, and why cosmic words work so well for pets, characters and spaceships.

Here are 90 space names, grouped into girls’ and boys’ names with meanings, cosmic words, planets and moons, astronomers and astronauts, and famous missions. For more, explore galaxy names and spaceship names, or look up real star names and constellation names.

How to choose a space name

  • Look for the myth behind it. Most planet and moon names come from Greek and Roman legends, so check the story (Phobos means “fear”).
  • Balance bold and wearable. Luna, Stella and Leo are everyday names; Nebula and Quasar are better for pets or characters.
  • Mind the jokes. Uranus is a planet name best left in the sky.
  • Use a middle name for bigger swings. “Lily Andromeda” or “James Orion” gives a cosmic touch without committing fully.
  • Go by the sky on the day. A baby born during the Perseids or a lunar eclipse has a built-in naming story.
