Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away. Scientists reported Friday that this black hole is 10 times more massive than our sun. And it's three times closer than the previous record-holder. It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun.
