How far away is the closest Black Hole?
We really can't "see" a black hole. What we "look" for is a high
concentration of x-ray emmissions. Some of these places (possibly
black holes) are a cluster called M15 approx. 35,000 light years away.
The most popular one is Cygnus X-1 which is an eclipsing binary star
system approx. 10,000 light years away - the closest I know of.
