Betelgeuse
Betelgeuse, also called α Orionis, is a large red star in the constellation of Orion.
It is the 10th brightest star in the sky, a red supergiant, and is a vertex of the Winter Triangle. Even though it is the α star of Orion, it is not the brightest. Rigel, also known as β Orionis, is actually brighter.
The name is a contraction of the Arabic Yad al-Jauza`, translated as the "armpit of the central one," indicating its position in the constellation of Orion. Because of its rich reddish color the star has frequently been referred to as the "martial one," and in astrology portends military or civic honors.
