New evidence found for Planet 9

A small team of planetary scientists from the California Institute of Technology, Université Côte d'Azur and Southwest Research Institute reports possible new evidence of Planet 9.

The work involved tracking the movements of long-period objects that cross Neptune's orbit and exhibit irregular movements during their journey. They used these observations to create multiple computer simulations, each depicting different scenarios.

The research team found that the most plausible explanation for the behavior of the objects was interference from gravity exerted by a large distant planet. Unfortunately, the simulations were not of the type that would allow the research team to identify the location of the planet.
