Best Answer

The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.

The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.

Do medium size stars become black holes true or false?

False. Only the most massive stars will become black holes.


Do medium size stars become black holes?

No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.


Medium size stars become black holes true or false?

False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.


Are black holes the size of stars?

Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.


Are dead stars black holes?

Yes. They get sucked into black holes all the time!


Why all dead big stars do not form black holes?

All dead big stars do not form black holes because sometimes the collapse of the star is stopped at a smaller size before it becomes a black hole.


What force causes extremely high mass stars to turn into black holes instead of nuetron stars?

Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.


Which stars primarily end up as black holes?

The most massive stars become black holes.


Are black holes stars?

No. Black holes are the remnants left behind when the very largest stars die.


What are the stars called when they become black holes?

They are called "black holes".


Where do the stars get sucked into?

Stars can be sucked into black holes.


Do stars ever into black holes?

Yes. When the most massive stars die, their cores collapse to form black holes.
