A red giant is a very big star that weighs about one-half to ten times as much as our Sun. Red giants get their name because they appear to be colored red and they are very large. Many red giants could fit thousands and thousands of suns like ours inside of them. Mira, Aldebaran, Arcturus and Gamma Crucis are red giants.
