Question

Black hole in solar masses

Answer 1

By comparison, the Earth is about 6,400 km in radius. So, the black hole is about 210 times smaller than the Earth by radius, or almost 10 million times smaller by volume. However, this black hole is 10 times as massive as the Sun, which in turn is about 330,000 times heavier than the Earth.Stellar-mass black holes are typically in the range of 10 to 100 solar masses, while the supermassive black holes at the centers of galaxies can be millions or billions of solar masses. The supermassive black hole at the center of the Milky Way, Sagittarius A*, is 4.3 million solar masses

Answer 2

The more likely mass is 5–10 solar masses. There is observational evidence for two other types of black holes, which are much more massive than stellar black holes. They are intermediate-mass black holes (in the centre of globular clusters) and supermassive black holes in the centre of the Milky Way and other galaxies.
