120 Celestial Cat Names: Stars, Moons & Space Missions
Some cats clearly belong to the night: the ones who stare out the window at the moon, patrol the house at 3 a.m., and sit in sunbeams like they are recharging. If your cat has that cosmic energy, a celestial name is the most natural fit in the world.
Below are 120 celestial cat names, organized the way the sky is organized: stars and constellations, moons and planets, the missions and explorers who reached for them, and the phenomena in between. Every entry carries a real space fact, because a name like Bellatrix deserves better than a shrug. Start with the most popular picks, then tour the four corners of the sky.
Key Takeaways
- The most-loved celestial names are short and luminous: Luna, Stella, Nova, Vega, Altair. Two syllables are the easiest for a cat to learn.
- Every name below is tied to a real star, constellation, moon, planet, or mission. We checked the astronomy so you do not name your cat after a typo.
- Match the name to the coat: Eclipse or Umbra for black cats, Polaris or Halo for white ones, Mars or Comet for gingers. Our black cat names and white cat names lists go deeper.

This is the scholar's lane: every name here is a real object you can find on a star chart, from brilliant Sirius to obscure Circinus.

Moon & Planet Cat Names
Moons with geysers, planets with rings, and dwarf planets with attitude: the solar system as a naming menu.

Cosmic Phenomena & Sky Word Cat Names
Eclipses, solstices, and the poetry of the night sky: short, evocative names for dreamy cats.

They suit cats with a faraway gaze and a habit of staring out the window at nothing.

Tips for Naming Your Cosmic Cat
- Say it at the back door. You will call this name across the yard at midnight. If “Betelgeuse, dinner!” makes you laugh, shorten it to Geuse now.
- Run the giggle test. Uranus is a real planet and a terrible cat name. Some space words are better admired than shouted.
- Short names carry further. Luna, Vega, Mars, and Io-style two-syllable names are the easiest for a cat to learn.
- Match the coat to the cosmos. Eclipse and Umbra were made for black cats; Polaris, Halo, and Enceladus suit white ones; Mars, Comet, and Fornax fit gingers.
- Give long names a nickname. Decide the everyday version on day one (Cassiopeia becomes Cassie) so your cat learns one consistent sound.
- Check the fact, not just the vibe. Every name above is tied to a real object. That is what separates a great celestial name from a random pretty word.
Our Pick
If we were naming a cosmic cat tomorrow, we would pick Vega for a girl and Altair for a boy: both are real, brilliant stars, both are two crisp syllables, and neither will ever feel dated. For a unisex pick, Nova is hard to beat: explosive, bright, and wearable for fifteen years.

Frequently Asked Questions
What is the most popular space name for a cat?
Luna leads by a mile, followed by Stella, Nova, and Leo (the constellation as well as the lion). They are short, pretty, and easy for cats to learn, which is why they stay popular year after year.
What is a good celestial name for a black cat?
Eclipse, Umbra, and Midnight are the classics. For something rarer, try Umbriel (the darkest of Uranus's large moons) or Orcus (a dark dwarf planet named for the Roman underworld).
What are some short celestial cat names?
Luna, Nova, Vega, Mars, Io-style picks: Lyra, Ara, Crux, Puck, Sol, and Star are all two syllables or fewer and carry beautifully across a room.
Can I name my cat after a constellation?
Absolutely. Lyra, Leo, Draco, and Crux all work wonderfully. Just give the long ones a nickname plan: Cassiopeia becomes Cassie, Betelgeuse becomes Geuse.
What is a good space name for a pair of cats?
Gemini (the Twins) is the perfect built-in pair name. Or go with mission pairs: Armstrong and Aldrin, Voyager and Pioneer, Castor and Pollux.
Are planet names good cat names?
Yes, and they suit big personalities: Jupiter for the gentle giant, Mars for the ginger firecracker, Saturn for the showy one with spectacular markings, and Pluto for the tiny underdog.
What are some cute space names for cats?
The cutest space names are the short, bright ones: Luna, Stella, Nova, Comet, Astro, Starla, and Moon. They are easy to say in a happy voice, easy for children to remember, and they suit kittens and playful young cats best.
What is a unique space name for a cat?
For something nobody else at the vet has, try Quasar (a blazing galactic core), Zenith (the top of the sky), Solstice, Vesper (the evening star), or Umbriel (the darkest moon of Uranus). Unique space names work best when they are still easy to pronounce: test yours by saying it out loud three times fast.
Was there ever a real cat in space?
Yes: a French stray named Felicette became the first and only cat in space in 1963, launched on a suborbital flight and recovered safely. She is the ultimate trivia answer for space-loving cat owners, though most people name their cat after the stars rather than the astronaut.
