If you’re looking for a baby name that’s out of this world, turn your attention to the sky and consider space names and celestial names — they’ll have you over the moon!

Space names aren’t exactly a new trend when it comes to baby names  — singer Erykah Badu named her daughter Mars, Sex and the City star Chris Noth named his son Orion, stylist Rachel Zoe named her son Skyler, and A-list couple Scarlett Johanssen and Colin Jost named their baby Cosmo. But they came back into the news this week when Chrissy Teigen and John Legend revealed that their new baby girl is named Esti, which means “star” — pairing quite nicely with big sister Luna!

Clearly, celestial names are a hit with the stars. But is a space name right for your little star? We asked Ophira Edut of The AstroTwins why these names are resonating with celebrities and non-famous folks alike these days.

“With things so haywire on THIS planet, so much uncertainty and things that are hard to explain, people are connecting to nature and its cycles for a sense of comfort and perspective,” Edut explains. “We’ve lost some of our collective faith in humanity, so naming people after other people isn’t resonating with the whole population anymore. Also, since a number of millennials, who are the babymaking age now, have either abandoned or supplemented traditional religion with spirituality, it makes sense that they’d want their kids to have a connection to the divine.”

Edut is a fan of lyrical takes on the space names theme, such as Celeste, and names of mythological constellations. “There are many cools ones in other languages, as well,” she adds.
