Io in 3D — live position and orbit

The innermost Galilean moon, shaped by intense volcanic activity driven by Jupiter tides.

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