Hygiea in 3D — live position and orbit

The fourth-largest asteroid. In 2019 it was found to be nearly spherical, so round it may qualify as the smallest dwarf planet in the Solar System.

Hygiea is shown at its real position, computed from NASA/JPL ephemeris data. The view opens on Hygiea; 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.
