2011 QF99 - Motion next 1 kyr

Short-term Animation showing the motion of 2011 QF99, as seen from above the north pole of the Solar System. The video initially shows the position of Uranus and 2011 QF99 at the time of discovery and then shows their motion for the next 1 kyr. The dotted lines are the average orbits of the planets. The left panel is in the stationary reference frame, while the right panel is in the "Uranian co-rotating frame", which spins at the same rate as Uranus, cancelling out the motion of Uranus and thus showing the motion of 2011 QF99 relative to a video of the motion over kyr, see this other video:
