[[File:Betelgeuse NASA ESA.jpg|right|thumb|Betelgeuse, an example of a red giant star]]
A '''red giant''' is an enormous, highly luminous star, typically tens to hundreds the times the diameter of our own [[sun]], that represents the late stages of the [[stellar evolution]] of a main sequence [[star]]. It is typically between 0.5 and 6 solar masses.. <ref>The Cambridge Atlas of Astronomy (2nd ed.). Cambridge University Press. 1988. pp. 255. ISBN 0-521-36360-8.</ref>
