# Haumea

*In the Solar System*

A dwarf planet shaped like a rugby ball, and it is spinning that turned it into one: it turns once every four hours, faster than anything else its size, almost certainly after a collision that also gave it two moons and a family of fragments on similar orbits. It was the first body out here found to have a ring, in 2017; Quaoar turned out to have two of its own in 2023, so the ring is no longer unique, only early. The figure this map draws it at is a single radius for a body that is roughly 2,100 by 1,680 by 1,070 km, which is a simplification the shape itself contradicts.

| | |
| --- | --- |
| Radius | 780 km |
| Around the equator | 4,901 km |
| Mass | 4.01 x 10^21 kg |
| Compared with the Earth | 0.001 × |
| From the Sun | 7,444,150,384 km (-39,573 km/d) |
| From the Earth | 7,530,132,950 km (+1,632,693 km/d) |
| A signal takes | 6 h 59 m |

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.
