A grapefruit-sized black hole may be hiding in our solar system BGR

The hunt for the ever-elusive Planet Nine has taken scientists down some very strange roads. The idea that a planet exists in the outer reaches of our solar system and can t be easily seen has been floating around for some time, and observations of other objects in the area suggest that there s something big generating a gravitational pull. The easiest explanation would be a planet, but it s not the only possibility.

Now, scientists from Harvard University in partnership with the Black Hole Initiative want to test the theory that the object that appears to be lurking on our system s edge is actually a black hole. Yep, you read that correctly; there may be a black hole lurking right in our cosmic back yard.
