Selene (Σελήνη) is the name of the Greek goddess of the moon — drawn each night across the sky in a chariot pulled by two white horses. She is the sister of Helios (the sun) and Eos (the dawn). The element selenium was named after her by the chemist Berzelius in 1817.
Selene has been quietly available as a girl's name for centuries and has been rising steadily in the 2020s. It now sits in the U.S. top 425 — a sharper, more classical alternative to Luna for parents who want a moon name with Greek roots.
Selene reduces to nine — the number of compassion and quiet light.
