Here's a table of information on the classification of black holes. Let's look at the largest, most massive, black hole that is still classified as a "Micro black hole." It has the same mass as the moon, 7.35x10²² kg, and a diameter of 0.1 mm. Let's say you are "standing" on this black hole. What is the value of the acceleration of gravity, g, on the surface of the black hole (at your feet)? What is the value of the acceleration of gravity, g, at the top of your head (1.7 m from surface of the black hole)?

Black hole Classifications
