Visually, it is tens of thousands of times brighter than the Sun; most of its radiation is in the ultraviolet, and when this is considered, it is approximately one million times brighter. A supergiant is a very large type of star which is ~10 to 50 solar masses on the Hertzsprung-Russell diagram. ...
