@Kaagan: The sun has a diameter of 1 392 684 km. If the sun was a black hole, it would be about 3 km, and Saggitarius A* has 4 000 000 times the mass of the sun, therefore it would have a diameter of 12 000 000 km.
Still less than earth's orbit, d = 2 r = 150 000 000 km.

idk about this. black holes are incredibly dense(a singularity or the maximum denseness something can be). The super massive black hole in the center of our galaxy, is smaller than our sun.
