Eros in 3D: live position and orbit

The first asteroid ever orbited and landed on: NASA’s NEAR Shoemaker circled it for a year and touched down on its surface in February 2001.Eros is shown at its real position, computed from NASA/JPL ephemeris data. The view opens on Eros; 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.
