Gemini is a northern constellation between Cancer and Taurus, containing the stars Castor and Pollux represented as twins sitting together. Castor and Pollux were stepbrothers. Castor was born of Tyndareus and Leda, whereas Pollux's father was Zeus. The twins grew inseparable, and when Castor was killed in the battle, Pollux was so grief stricken that he took his own life to join his brother at death. In honor of the brothers' great love, Zeus placed them among the stars.
The astrological period called Gemini takes the period from May 21 to June 21.
