Sedna in 3D — live position and orbit

One of the most distant and coldest known objects in the Solar System, journeying on an extremely elongated, multi-millennial orbit that carries it beyond the Kuiper Belt toward the inner edge of the hypothesized Oort Cloud.

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