Gemini constellation

Gemini is an ancient zodiac constellation representing the Dioscuri, Castor and Pollux, sons of Leda. Pollux was immortal but Castor was not; when Castor was killed, Pollux asked Zeus to let him share his immortality with his brother, and so the two were placed in the sky together. Their heads are marked by the bright stars Castor and Pollux. Pollux, an orange giant, is brighter than Castor and has a planet, while Castor is a multiple system of six stars. Other named stars include Alhena, Tejat, Propus, Mebsuta, Alzirr, Wasat and Mekbuda. At the Twins' feet lies the open cluster M35, and every December the Geminids, one of the richest meteor showers of the year, radiate from here. From Central Europe, Gemini stands high on winter evenings, north-east of Orion.
