Anything can turn into a black hole if it is collapsed hard enough, even you. They are mainly formed from collapsed matter of stars. Thousands and possibly even millions are traveling through our galaxy right now. And if one enters our solar system, it’s over. Black holes are insanely large as the largest black hole phoenix A* is 66,000,000,00 solar masses. Once something crosses the event horizon,
there is no escape…ever. Once you’re in the center of the black hole, you are crushed into infinite density. Truly a scary thing.
