04. How big can a black hole be? (A K2S Question)
From The Space Library
Scientists believe that some of the largest black holes found in the centers of very large galaxies may contain a billion solar masses. The event horizon for such a large black hole would be about the distance from our Sun to the planet Uranus—about 1,800,000,000 miles.
