Comet

The ancient Greeks were known to ponder the universe and study the great unknown of the skies. When they first set their eyes upon comets, they didn't have the terminology, but some 500 years after the supposed first sighting, the ancient Greeks finally decided on kometes. This word means "head with long hair," referring to the characteristic tail trailing the dazzling comets across the sky. Whether baby's crown is destined for great lengths or they'll be an astrophysicist, the gender-neutral name Comet will suit them perfectly.
