Orion


Orion (astronomy), constellation located on the celestial equator east of Taurus. It is an oblong configuration with three stars in line near its center. It is represented on pictorial charts as the figure of Orion, the hunter in Greek mythology, standing with uplifted club. Three bright stars represent his belt and three fainter stars aligned south of the belt represent his sword. Alpha (a) Orionis, or Betelgeuse, is located in the left corner of the oblong, corresponding to Orion's shoulder. Beta (β) Orionis, or Rigel, is diagonally opposite Betelgeuse. A nebula surrounding the three stars marking Orion's sword is one of the most conspicuous bright nebulas in the heavens.

In Greek mythology, Orion is the handsome giant and mighty hunter, the son of Poseidon, god of the sea, and Euryale, the Gorgon. Orion fell in love with Merope, the daughter of Oenopion, king of Chios, and sought her in marriage. Oenopion, however, constantly deferred his consent to the marriage, and Orion attempted to gain possession of Merope by violence. Incensed at his behavior, her father, with the aid of the god Dionysus, put Orion into a deep sleep and blinded him. Orion then consulted an oracle, who told him he could regain his sight by going to the east and letting the rays of the rising sun fall on his eyes. His sight restored, he lived on Crete (Kríti) as the huntsman of the goddess Artemis. One version of Orion's story relates that the goddess eventually killed him because she was jealous of his affection for Aurora, goddess of the dawn. After Orion's death, Artemis placed him in the heavens as a constellation.
