Celestial Baby Names
Choosing your baby’s name is one of the most important decisions you’ll make as a parent and is intended to last their lifetime. Celestial names can be a beautiful and meaningful tribute to the child you will love to the moon and back!
Look to the Sky for Inspiration
When I was choosing names for my babies, it was a struggle made out of love. I wanted to name them mindfully and not assume who they might be while still putting my energy into what they’d be called their whole lives.
It’s a major decision! I didn’t know if they’d be artists, mathematicians, wanderers, or scientists. I knew their hearts, but not yet their personalities.
Names chosen from your own heart, love, and wisdom are the best way to go. Celestial names for your baby are timeless while evoking a similar whimsy of ethereal names.
I love that celestial names are science and mythology at once, an equal balance of facts and mystery. I also love astrology names, and a few are sprinkled throughout this list. But if you want a unique and mystical name but astrology is not your thing, these celestial names will give you some great options.
“Celestial” Meaning for Baby Names
Celestial means positioned in or relating to the sky and outer space, as observed in astronomy. This list of celestial baby names includes names that mean star, names of planets, moons, and collections of stars. They all have science, mythology, and magic to them!
Instead of separating these names by gender, they are all in one list. Many of them are totally gender neutral, but the feeling of feminine or masculine as it relates to gender is entirely up to you. Of most importance is that your baby knows their name was chosen with love and meaning.
