About the Gemini zodiac sign
Gemini — the Twins — is the mutable air sign of the zodiac, ruled by Mercury. Gemini energy is fast, verbal, and built for taking in information from many channels at once. Famous Gemini celebrities include Angelina Jolie, Marilyn Monroe, Kanye West, Johnny Depp, and Paul McCartney. The Gemini signature is endless curiosity, a habit of talking through ideas, and a chronic boredom with anything that doesn't change.
