Styx in 3D: live position and orbit

The smallest and innermost of Pluto’s four small moons, tumbling chaotically under the combined pull of Pluto and Charon.

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