75 Out-of-This-World Celestial-Themed Baby Names 💫

Aurora

This name stems from the Roman goddess of sunrise, but also relates to the phenomenon that causes the Aurora Borealis, AKA the Northern Lights.

Caeli

For the brightest star in your life, name a baby girl Caeli after the Caelum Constellation. In fact, the largest star within this constellation is known as the Alpha Caeli—fitting if she’s the first girl in the family.

Cassiopeia

Give a modern twist to the name Cassie after Queen Cassiopeia, the vain queen, in Greek mythology. While your little one may not be vain, there’s no doubt that the name itself is beautiful.

Celeste

It doesn’t get any more celestial-themed than a shortened version of the word itself, right?

Estelle

Like Stellan and Stella, Estelle is also inspired by the Spanish word for star, “estrella.”

Eva

Give your little girl a name that has an ‘out of this world’ meaning. EVA in space terms means “Extravehicular Activity,” or in other words, it’s a fancy way to say “spacewalk.” The name Eva also means “mother of all living.”

Faye

This name is of English origin and stems from “fairy” (familiar characters in Greek mythology), but it is also inspired by Hervé Fay, a famous astronomer.

Flora

Flora is the name of an asteroid currently orbiting the sun and is also the goddess of spring and flowers in Roman mythology.

Halley

Name your new bundle of joy Halley after Halley’s Comet. Every 75 years, Halley’s Comet makes an appearance in Earth’s orbit. It’s expected to be seen again in 2061, so this celestial sighting may be a once-in-a-lifetime experience for your little one, in the future. Consider this special name a poetic gesture to your baby girl, who might one day witness the very comet that she’s named after.

Liora

Are you looking for a name that exudes star-like qualities? The name Liora means “my light” in Hebrew.  

Luna

Luna is a direct translation of “moon” in Spanish, and while that could be reason enough for the name, it also happens that the moon is the ruler of the Cancer zodiac sign.

Mira

If you wished upon a star for a baby girl, it’s only fitting to name her Mira after the shooting star, Mira. This giant star travels at supersonic speeds through the Milky Way.

Nova

For a sweet and simple name in astronomical terms, nova simply means “star.”

Ophelia

While this gorgeous name may seem like a perfect option for a literary fan because of its Shakespearean roots, it also happens to be the name of a small moon of Uranus.

Phoebe

Saturn’s largest moon is named Phoebe, after the Greek goddess of wisdom. This cute girl’s name also means “bright” and “radiant.”

Selene

Tell your daughter she’s named after Selene, the goddess of the Moon. How sweet is it knowing that you’ll think of her whenever you see the moon? Selene means “light” and “brightness” in Greek.

Xenon

Name your baby girl Xenon after Zenon Kar, a teen living on a futuristic space station from the 2000s DCOM movie Zenon. But in more technical terms, some spacecraft use xenon in ion thrusters to efficiently thrust through space.

Apollo

In Greek mythology, Apollo is the God of the Sun and the son of Zeus, giving him a unique name that represents brightness and strength.

Caelum

While the Caelum constellation may be one of the smallest constellations, your baby boy will shine bright with this adorable name. The name Caelum is of Latin origin and means “heavens” and “sky.”

Cosmo

Through an astrological lens, the cosmos is another term for the universe, as it implies viewing the universe as a complex entity.

Cyrus

Pivoting from Greek mythology, Cyrus means “sun” in Persian mythology, which leans more into the celestial theme than the zodiac.

Elio

Pronounced as El-ee-oh, this charming name stems from similar places in Greek mythology, translating to “sunshine” or “sunlight.”

Leo

A classic name with direct inspiration from the zodiac sign itself!

Orion

I almost feel like this baby name rec goes without saying: Orion’s Belt is one of the most famous celestial constellations!

Stellan

It’s more common to see the name Stella for girls, derived from “estrella,” the Spanish word for star. Stellan is a unique take on this adaptation for a baby boy.

Titan

Titan is not only the largest of Saturn’s moons, but it was also the name of an ancient race of giants in Greek mythology.
