After Leo, this is one of the most usable names in the zodiac: part ancient, part new-age, part high-tech. In the night sky, the constellation Gemini is present all year round in both hemispheres. It has been associated with twins since ancient times, and its two brightest stars are named Castor and Pollux after the twins of Greek mythology. It also has STEM connections: Project Gemini was a NASA spaceflight program before Apollo.

Astrological sign with enough rhythm to make a plausible astral name.
