Do you know these 30 famous Gemini? Celebrities with birthdays under the zodiac sign
Gemini, in astronomy, zodiacal constellation lying in the northern sky between Cancer and Taurus, at about 7 hours right ascension and 22° north declination. Its brightest stars are Castor and Pollux (Alpha and Beta Geminorum); Pollux is the brighter of the two, with a magnitude of 1.15, and is the 17th brightest star in the sky. The summer solstice, the northernmost point reached by the Sun in its annual apparent journey among the stars, lies in Gemini. This constellation also contains the isolated pulsar Geminga.
In astrology, Gemini is the third sign of the zodiac, considered as governing the period from about May 21 to about June 21. It is represented by a set of twins (or in Egyptian astrology by a pair of goats and in Arabian astrology by a pair of peaco*cks). In addition to their identification as Castor and Pollux, the twins have also been related to other celebrated pairs, such as the younger and older Horus or Romulus and Remus.
