There is no "average" mass for black holes throughout the entire universe. Black holes range greatly in mass, depending on how they were formed, and how long they have existed if you take Hawking Radiation into account. Mass can be anywhere between a couple hundred protons, such as those created by cosmic rays striking Earth's atmosphere, or an enormous mass such as those in the center of almost every spiral galaxy.

The relevant magnitude for black holes is their mass. This can vary from a few solar masses (the smallest-known stellar black holes) to about 20 billion solar masses (the largest-known supermassive black hole).

Can a black hole get to the size of a planet?

A black hole can definitely get to the size of a planet. The width of the largest known supermassive black hole is thought to be over ten times the size of the entire orbit of Neptune around our Sun.

Does a medium size star become black holes?

The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.


What would happen if two black hole were to merge into each other?

What is the minimum and maximum size of the black hole?

There isn't one. It depends on how much matter the collapsed star (black hole) has gathered.


Is an Intermediate-mass black hole a type of black hole?

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.


Does the sucking of masses increase the size of a black hole?

yes
