Answer To Question 212

A212: A black dwarf is a small, very dense, cold, dead star. It is made mostly of carbon. This dark star is what remains after a red giant star loses its outer layers, forming a planetary nebula and then a white dwarf. The nuclear core of a black dwarf is depleted. Black dwarfs are about the size of the Earth (but tremendously heavier)! Our sun will someday turn into a black dwarf.
