This simulation shows the proposed ninth planet of the solar system, as detailed in 'Evidence for a Distant Giant Planet in the Solar System' by Konstantin Batygin and Michael E Brown, and featured in many media articles in late January 2016. The Kuiper Belt objects 2012 VP113, 2013 RF98, 2004 VN112, 2010 GB174, 2007 TG422, and Sedna are included.
You can run the simulation to watch the motions of the proposed ninth planet and the Kuiper Belt objects. If you want to significantly speed up the simulation, you can remove the inner planets. Since different computers run at different speeds, you may need to edit the evolution time step to get the simulation to run at an acceptable rate.
