The radius of the event horizon of a black hole with the mass of the Sun would be about 3 kilometers, about the same size as your city, town or village. If the Earth could be compressed into a black hole, the radius of its event horizon would be 1/330,000 of this, because the mass of the Earth is 1/330,000 times the mass of the Sun. ... 30,000,000 . ... 20,000 . ... Black hole event horizon . ... MYTH: All stars collapse to become black holes upon their death. ... MYTH: Black holes are very dense. ...
