      Black holes can be all different sizes. There are micro black holes (also called primordial black holes) that are really quite tiny, stellar mass black holes that are between 10 and 100 times the mass of our Sun, and the types of black holes that are in the very centre of galaxies, which are millions or even billions of times more massive than our Sun. A black hole that weighed as much as our Sun would only have a size of about 6 KM across. This is much smaller than our Sun.
