According to Steven Hawkings there is approximately 1 blackhole per cubic light-year of space. Apparently these are very small, created during the birth of the universe. Blackholes are actually not as complex as you may think, they are just super-compressed mass. Otherwise blackholes behave exactly the same as any other spacial object. So assuming Steven is correct: : Can someone kindly tell me how far the closest Black Hole is from the Earth? - within 1 light year. : Does it move? - probably. : If it does, how fast? In what direction? - we probably will never know for sure. The likely-hood of ever experiencing a blackhole is so miniscule as to be totally impossible.
