Callisto in 3D: live position and orbit

The outermost Galilean moon, heavily cratered and likely hiding a deep salty ocean.

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