It’s no secret that astrology is an increasingly hot topic. While trying to get pregnant, some people aim for a birth date that falls under a specific zodiac sign. Others send the baby’s birth chart in the family group chat just minutes after delivery. If all things celestial and astrological pique your interest—but not quite to that extent—baby names that fall under these themes are abundant and adorable. The constellations, stars, space, and Greek mythology are just a few categories to pull inspiration from to find the perfect name for your baby. Read on for some of the cutest astrological and celestial baby names—for boys, girls, and some gender-neutral options—that are out of this world.
