Betelgeuse

  • by

Betelgeuse, Alpha Orionis, is the second brightest star in Orion constellation and the ninth brightest star in the sky. It is a supergiant star, distinctly red in colour, located at an approximate distance of 643 light years from Earth. It is an evolved star, one expected to explode as a supernova in a relatively near future.

Betelgeuse is a large, bright, massive star easily found in the sky in the winter months because it is part of a familiar pattern formed by the celestial Hunter. The red supergiant marks one of Orion‘s shoulders, while the hot, bright giant Bellatrix, Gamma Orionis, marks the other.
