A black hole inside our Solar System

For years astronomers have thought that there could be a ninth planet in the solar system known as Planet X

That lies in the icy realm far beyond Neptune, around 150 billion kilometers from the sun and could be 15x bigger than Earth

Even though the idea of Planet X is totally hypothetical, some astronomers think that it might exist

But according to a new research, the Planet X could actually be a primordial Black Hole, only about the size of baseball

Primordial Black holes are predicted to have popped into existence within the first few seconds after big bang

The gravitational disturbances beyond Neptune is more likely to be caused by a primordial Black hole

The existence of such Black holes have never been confirmed

But if primordial Black hole exist in our solar system, it would be a good source of Dark Matter.
