Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow.

Adventurous parents are starting to look back to names of ancient gods like Mercury, Zeus, and Apollo. This one is also a planet and a metallic element, and has a friendly nickname, Merc.

This Roman mythology (and planet) name would be very hard to handle. It derives from a root meaning cloud.

A simple and appealing unisex Korean name with many possible meanings, depending on the hanja characters used. Coincides with the English word "sun", which is a nice bonus.

A beyond-bold shooting-star name choice, sure to raise some relatives' eyebrows.
