Caltech astronomer and planet killer Mike Brown claims he has found evidence of a potential planet in the Kuiper Belt roughly 100 billion miles from Earth, reports The Daily Beast.

He explained to the publication that the object is possibly “six times more massive than the Earth and the fifth largest planet in our solar system.”.
