Haumea in 3D: live position and orbit

It spins in under 4 hours, the fastest of any large body in the Solar System, which has stretched it into an egg shape. In 2017 it became the first trans-Neptunian object found to have a ring.

Haumea is shown at its real position, computed from NASA/JPL ephemeris data. The view opens on Haumea; you can travel in time, switch between the educational overview and the true-scale voyage, and compare it with every other body of the solar system.
