about 1/3 of a neutron star
A black hole's size is determined by its mass, which is the amount of matter it contains. The more mass a black hole has, the larger its size. The size of a black hole is typically measured by its event horizon, which is the point of no return where gravity is so strong that not even light can escape. The event horizon's size is directly related to the mass of the black hole.
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
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.
No.
yes and no depends on size of hole :]
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.
Firstly our sun is too small to become a black hole. Only stars that are a million to a billion times our sun do this, because they burn through their fuel quickly, unlike our sun. A typical black hole has 3 times the mass of our sun
You would have a black hole the size of the combined mass of the two black holes.
The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.
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.
There isn't one. It depends on how much matter the collapsed star (black hole) has gathered.
yes
