*In the Solar System*

One of the largest known bodies beyond Neptune, here for its size, and one of the last big ones to be named - it was 2007 OR10 for a decade after its discovery. It is on a long, steeply tilted orbit that takes it out past 100 AU, it is unusually red for something this far out, and it has a moon, Xiangliu, found in old Hubble frames after the fact. Nothing is going there.

Distances and speed are computed from JPL Horizons trajectories and are true of 2026-09-05, changing at the rate given beside each. The interpolation itself is good to a few kilometres; what ages these figures is the date, not the arithmetic.
