It has a very strong gravitational force, even light also can't escape from the gravitational force of the black hole. I have told you about this in my post called 'Nuclear fusion in stars' or you may see this video to know more about how a black hole is formed . Where Is Our Nearest Black Hole? The closest black hole we know is V616 Monocerotis , also known as V616 Mon . It's located about 3,000 light years away, and has between 9-13 times the mass of the Sun .
