Description:
Orion's Belt is an asterism in the constellation of Orion The Hunter. Other names include, the Three Kings, the Three Sisters and for Spanish speakers "Las Tres Marias" To the naked eye the three bright stars are nearly equally spaced in a line, spanning an angular size of ~140′ (2.3°). In spite of their spot-like appearance, only Alnilam is a single star; Alnitak is a triple star system, and Mintaka a hextuple. Each of the three owe their luminosity to the presence of one or more blue super giants. The brightest as viewed from Earth is Alnilam, followed by Alnitak and Mintaka. Together, the 10 stars of the three systems has a combined luminosity of nearly one million times (~970,000) that of the Sun's.
