Until recently, one of the closest orbiting each other pairs of supermassive blackholes was found in NGC 7727. That pair is about 89 million light-years away from Earth. Those black holes are only 1,600 light-years apart from each other. Another pair in OJ 287, about 3.5 billion light-years from Earth, are only separated by about 0.3 light years. Now scientists have discovered a pair orbiting each other at a distance of 200 AU to 2,000 AU apart, about 0.003 to 0.03 light years.
