- A predicted consequence of Planet Nine is that a second set of confined objects should also exist. These objects are forced into positions at right angles to Planet Nine and into orbits that are perpendicular to the plane of the solar system. Five known objects (blue) fit this prediction precisely. http://mediaassets.caltech.edu/documents/45-p9_kbo_extras_orbits_2_.jpg 42 comments space
