Astronomers have long speculated in regards to the existence of "Planet 9", a super-Earth-sized planet in the outer regions of our solar system. It has been hypothesized as evidence for the unusual cluster form of asteroids as well as comet orbits out beyond Neptune. The planet, if it does not exist, would likely be 5 times the size of Earth also orbits around the sun at 250 times the distance. Being so far away, we have not been able to catch a glimpse of it yet. The mysterious, hidden planet is, in fact, only a hypothesis at this point and there have been other explanations for the unusual paths taken by objects like asteroids. Now there is a new theory that states that a black hole. A primordial black hole to be more specific. Primordial black holes are hypothetical black holes that originated after the Big Bang. In comparison with other black holes, a PBH is old and small. Their existence has been difficult to prove as authors James Unwin and Jakub Scholtz speculated to Gizmodo, this primordial black hole might be the scale of a bowling ball. The black hole is so small for Unwin and Scholtz to include a 1:1 diagram it in their paper. But, the new paper suggests the strange orbits in the outer regions of our solar system might be the results of one of these primordial black holes. A bowling ball-sized black hole of the outer reaches of the solar system is an outlandish concept; however, at this point, it is no much less plausible than the existence of a super Earth-sized planet. Each situation can be equally thrilling for astronomers.
