Gemini is one of the 48 constellation established by Claudius Ptolemy. Its area is 514 square degrees and it has 118 stars that can be seen with ecliptic naked eye. It is one of the twelve constellation. The star Pollux in the west is a first magnitude star, and Castor in the east is a bright second magnitude star. In Mesopotamia, Gemini was called the twins with the big head and the small one in the middle. In Greek mythology, they are the Spartan princes Castor and Polydeuces. Leda, the wife of King Tyndareus of ancient Sparta, was very beautiful, and Zeus liked her, so he transformed into a swan to approach the queen without the king knowing. Leda then laid two eggs, and the brothers Castor and Polydeuces and the sisters Clytemnestra and Helen were born. Castor was the king's son and an ordinary human, but Polydeuces was said to be immortal, with the blood of Zeus in his veins. When his brother Castor died, Polydeuces was so sad that he asked Zeus to put them both in the sky and they became constellation.

The Pleiades star cluster is located on the bull's shoulders, and the Hyades star cluster is located on the bull's face. It is said that the bull that forms constellation represents the form that the great god Zeus took when he kidnapped Europa, the daughter of the Phoenician king. Zeus and Europa eventually arrived on the coast of Crete and were married.

There are two anecdotes in Orion. (1) Orion, a brave giant hunter, incurs the wrath of the gods when he says, "There is no one under this heaven who can match me." One day, when Orion is walking, the earth suddenly cracks, and a large scorpion jumps out of it. Orion is stung in the leg by the scorpion and dies. Therefore, it began to appear as constellation in the opposite season, winter, as if escaping from the Scorpius that appear in the summer night sky. These two constellation cannot be seen in the same sky, and there is such a story behind it. (2) The goddess Artemis, who is also the god of hunting, fell in love with Orion. Artemis's brother Apollo, who does not like this, sees the giant Orion walking in the sea with only his head out, and calls Artemis. Apollo says that Orion's head is a rock and taunts him, saying, "No matter how much you do, you won't be able to shoot through it." Artemis took advantage of the provocation and fired an arrow. The arrow hits Orion in the head, and Orion dies. It is said that when Artemis learned that it was Orion that she had shot, she asked her father, the great god Zeus, to add Orion to the constellation. As a result, Artemis began to ride by Orion once a month in a silver car.
