Hydra in 3D — live position and orbit

Pluto's outermost known moon, the fastest tumbler of the small moons, spinning once roughly every 10 hours.

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