How is the star Betelgeuse different from the sun? Betelgeuse is a supergiant red star that is nearing its end of life. The sun is a relatively small main sequence star in the middle of its life. It is believed that Betelgeu â¦ se is only 10 million years old, and that it has evolved so rapidly because of its extremely high mass - it is one of the largest stars we know of - and its demise as a type II supernova is predicted within only the next 1 million years.
