2015 RR245 was recently announced, in a highly eccentric orbit in the KBO. From what I understand, the so called "Planet 9" was predicted because these objects tended to be pointed in a particular direction. How is this object pointed relative to the other KBOs?
It was the first thing I thought too, but I would say it won't count in the statistics. The earlier paper by Batygin & Brown was talking about bodies orbiting further out.
2015 RR245 orbits between 33.7 and 129 AU. The "cluster" of bodies considered in the paper have aphelion distances from 150 AU upwards. So I think it would be a mistake to try and fit this new body into the existing figures.
