Gemini is one of the constellations of the zodiac. It was one of the 48 constellations described by the ancient astronomer Ptolemy around 2 AD. Today, it is one of the 88 modern constellations we know. Its name comes from Latin and means "twins." This name refers to the famous twins Castor and Pollux from Greek mythology. The symbol for Gemini is Gemini.svg (Unicode ♊).

Gemini is located between Taurus to its west and Cancer to its east. You can find Auriga and Lynx to the north of Gemini. To the south, you'll see Monoceros and Canis Minor.

Amazing Meteor Showers

The Geminids are a fantastic meteor shower. You can see them best around December 13–14. During this time, you might spot about 100 meteors per hour! It's one of the brightest and most active meteor showers.

There's also another meteor shower called the Epsilon Geminids. These meteors peak between October 18 and October 29. They are harder to see because they happen at the same time as the Orionids meteor shower. However, Epsilon Geminid meteors move much faster than Orionids.

The Mythology of Gemini

In ancient Babylonian astronomy, the stars we call Castor and Pollux were known as the Great Twins. These Twins were seen as minor gods. They were named Meshlamtaea and Lugalirra. These names meant 'The One who has arisen from the Underworld' and the 'Mighty King'. Both names were titles for Nergal, a powerful Babylonian god of sickness and the king of the Underworld.
