Gemini is one of the constellations of the zodiac. It was one of the 48 constellations described by the 2nd century AD astronomer Ptolemy. It is one of the 88 modern constellations today. Its name is Latin for "twins." It is from the twins Castor and Pollux in Greek mythology. Its symbol is 
(Unicode ♊).
Location
Gemini lies between Taurus to the west and Cancer to the east. Auriga and Lynx are to the north. Monoceros and Canis Minor are to the south.
Meteor showers
The Geminids are a meteor shower that can be seen best on December 13–14. People watching it see about 100 meteors per hour at most. It one of the richest meteor showers. The Epsilon Geminids peak between October 18 and October 29. They have only been recently confirmed. They overlap with the Orionids. This makes the Epsilon Geminids hard to see. Epsilon Geminid meteors move faster than Orionids.
Mythology
In Babylonian astronomy, the stars Castor and Pollux were known as the Great Twins (MUL.MASH.TAB.BA.GAL.GAL). The Twins were thought of as minor gods. They were called Meshlamtaea and Lugalirra. These names meant 'The One who has arisen from the Underworld' and the 'Mighty King'. Both names can be understood as titles of Nergal, the major Babylonian god of plague and pestilence. He was king of the Underworld.
