Eris in 3D — live position and orbit

More massive than Pluto. Its discovery in 2005 forced astronomers to define what a planet is, and cost Pluto its status. It roams up to three times farther from the Sun than Pluto.

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