Gemini

The constellation Gemini is really a set of twins! If you live in the Northern Hemisphere, you can see Gemini in the winter and spring. If you live in the Southern Hemisphere, you can see it in the summer and fall.

Gemini is really easy to find. All you have to do is look for the two bright stars that make up the heads! They are called Castor and Pollux. Once you find the heads, look for their arms and legs. Gemini is right between Cancer and Taurus.

In Greek myth, the two twins are named Castor and Pollux. They were the sons of Zeus and Leda. The Romans called them Romulus and Remus. They were raised by Chiron. The heroes were put into the sky to live with the gods.
