Gemini (Pronounciation:Gem-in-eye, Abbrev:Gem) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Gemini takes up 513.761 sq. degrees of the night sky which equates to 1.25% of the night sky. The constellation gets its name as it name means The Twins . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.
Gemini is a member constellation of the Zodiac grouping, a group of 12 star signs that astrologers use to predict someones future based on their date of birth and which constellation appeared when the Sun set. The Zodiac year may be divided up equally between the twelve signs but when they appear in the night sky no longer conforms to the Zodiac calendar. Gemini is an equatorial constellation that can be seen by countries nearest the Equator. The brightest star in Gemini is Pollux. There are 6 Extrasolar Planets (Exoplanets) detailed on this site.
Zeus seduced Leda, the wife of Tyndareus whilst as a swan. Helen and Pollux were born from eggs. At the same time, Castor and Clytaemnestra were born, children of Tyndareus. Pollux was the son of a god and an immortal, he could not die. They grew up as brothers, competing against one another in competitions and Olympics. During competition between them and their cousins, Idas and Lynceus, Castor died. Pollux asked Zeus to allow him to die so that he could be with his brother which Zeus allowed.
There are 11 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.
