Celestial Names: Beautiful Baby and Pet Names Inspired by Moons, Stars, and Galaxies

Some names feel timeless because they come from the sky itself. Across cultures and centuries, people have looked upward to the stars for inspiration — naming children, pets, ships, and even cities after the moon, constellations, planets, and distant galaxies.

Celestial names carry a sense of wonder. They can sound elegant, mysterious, playful, powerful, or deeply poetic. Whether you are searching for a baby name, a name for a new puppy or kitten, or simply collecting inspiration, astronomy offers a universe of possibilities.
