    Can there be a planet near black holes?

    From Wikipedia: "A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it."

    See: http://en.wikipedia.org/wiki/Black_hole

    So nothing too close can survive very long right? But I believe stars have fairly recently been observed in fast orbits around the black hole at the center of our Milky Way galaxy.. See the link below for an illustration. Only an expert could tell you if a planet in one of those systems could survive also, but my guess is this would be as close as a planet could get that wasn't being draw in to its destruction. Hope this helps. 😉

    It would be interesting to know whether there are PSR B1620−26 b satellites?
