Abstract

The study of Planet Nine has received a lot of attention of late. Recently it has been proposed that Planet Nine could be a Primordial Black Hole (PBH) lurking in our solar system. Earlier it was suggested by the present authors that Planet Nine could be degenerate object constituted mostly of dark matter (DM) particles, having their own distinct characteristic properties which were elaborated upon. Here we do a comparative study on whether the Planet Nine is a PBH or a DM Object, which would be relevant for future observations.
