Astronomers take virtual plunge into black hole - CNN.com: "Anyone worried about Earth being swallowed by a black hole should also be relieved to know the closest one astronomers know about is 3,000 light years away, which McClintock called a 'super, super, super safe' distance. He added that we wouldn't be sucked in even if the sun, which is only 8 light minutes away from Earth, were suddenly replaced by a black hole of the same mass."
