Give every moon of one planet a shared theme so readers can tell they belong together.
Moon names tend to sound pale, quiet and old. In our own solar system, most moons are named after figures from myth who were linked to the planet's god, which is why Jupiter's moons carry names like Io and Europa. This moon name generator follows that feel, building soft, short names and sometimes adding words like Minor, Prime or the Pale.
Use it when your sci-fi planet needs one moon or twelve, when a fantasy world needs twin moons for its calendar, or when you are naming a colony moon in a space game. Each press gives ten new moon names to pick from.
How to use the moon name generator
- Press Generate names to see ten moon names.
- Some results show a pair joined by and, which works for twin moons.
- Copy a name, or tap the heart to save it on this device.
- Pair the moon with its planet's name and check the two sound like family.
How moons in our solar system were named
Astronomers name most moons after characters connected to the god of their planet. Jupiter was the Roman form of Zeus, so his moons are named after people from Zeus's stories, such as Io, Europa, Ganymede and Callisto. Saturn's larger moons are named after Titans, the giants of Greek myth.
Uranus breaks the pattern. Its moons, like Titania, Oberon and Miranda, come from the plays of Shakespeare and a poem by Alexander Pope. This shows you can pick any rich source for your own moons, as long as each planet keeps one theme.
Naming moons for a fictional world
Start with how people on the planet see the moon. A moon that glows red during harvest might be called the Red Lady by farmers, even if astronomers use a formal name. Giving a moon both a common name and a formal name adds real depth to your setting.
Several moons work best with a theme. Sisters, hunters, gods of one family, or colours all make good sets. Then readers can tell your moons apart and remember them.
- One large moon: a single soft name, often feminine, like Selene.
- Twin moons: two names with matching sounds, such as Selene and Selis.
- Small rocky moons: plain or numbered names, such as Thyon IV.
- Colony moons: add Station or Prime for a lived-in sci-fi touch.
Example names and what makes them work
| Name | Why it works |
|---|---|
| Selene | Soft s and l sounds give the calm, silver feel of a classic moon. |
| Ilura Minor | Minor shows it is the smaller of two moons, a handy detail. |
| The Pale Orithe | A descriptive title in front reads like a name used by locals. |
| Selene and Selis | Twin moons with matching sounds feel like sisters in the sky. |
| Thyon IV | A numbered moon suits a mining or science outpost in sci-fi. |
| Caliope Station | Station turns a moon into a colony home for your characters. |
| Red Vesara | A colour in front hints at legends or omens tied to the moon. |
| Nimae | Short and gentle, easy to drop into dialogue or song lyrics. |
Tips for picking the right name
- Give every moon of one planet a shared theme so readers can tell they belong together.
- Add a folk name that ordinary people use alongside the formal name.
- Tie the moon's name to its colour, size or phase to make it easy to picture.
- Use moon names in your world's calendar, festivals or month names.
- Keep moon names shorter and softer than the planet they orbit.
Common questions
What are some pretty moon names?
Pretty moon names use soft letters and open vowels, like Selene, Nimae or Ilura. Endings such as -ene, -ia and -ora sound gentle. Press Generate a few times and read the results aloud to find one that feels calm and bright.
Why are so many real moons named after myths?
The planets were already named after Roman gods, so astronomers chose figures from those gods' stories for their moons. It keeps each planet's moons linked by one theme and makes the names easier to remember.
How do I name twin moons?
Pick two names that share a sound, a first letter or an ending, like Selene and Selis. This makes them feel like a pair. You can also give them opposite meanings, such as one bright and one dark.
Can I use these moon names in my story or game?
Yes. Each name is built from sound pieces, so you can use it freely in fiction, campaigns and space games. A quick online search before publishing helps avoid clashes with real moon names.
