A Prime Planet 9 Candidate Has Been Identified

Astronomers have scoured existing solar system astronomy data from two different collaborations, twenty-three years apart, to identify a single candidate for Planet 9 using the properties that previous studies have determined it should have. 

Further observation will be needed to determine if this candidate is actually Planet 9 or not, as they have only two point in time observations from twenty-three years apart to go on. But, they now know precisely where to look for it.

Previous comparison of the two yielded no candidates
