Orion /ori-on/ [2 sylls.] as a boys' name is pronounced oh-RYE-on. It is of Greek origin. Greek mythology: Orion was a mighty hunter, the son of Poseidon, who was turned into a constellation. The Orion constellation contains three of the most conspicuous stars in the nighttime sky.
Beta Orionis is the star's Bayer designation. The traditional name Rigel is first recorded in the Alfonsine Tables of 1252. It is derived from the Arabic name Rijl Jauzah al YusrÄ, the left leg (foot) of Jauzah (i.e. rijl meaning leg, foot), which can be traced to the 10th century.
