Andya, that is not correct. There is no more "sucking power" from a black hole than from a star of the same mass.
I agree with Vanadium 50. Relativistic affects are only apparent at very close distances. If our sun suddenly turned into a black hole, Earth's orbit would remain the same. Earth would be uninhabitable because of the lack of light, rather than being "sucked in".a planet to orbit a black hole has to be formed with the black hole lucky enough to be outside the sucking radius of the black hole ! !! as if it come out from space towards the black hole it has a tremendous probability to get sucked in before it orbits or until we discover a method to spot it ! so i guess if planets do orbit a black hole , it might be a temporary one , as they would end up crashing the black hole after a while
