Mercury in 3D — live position and orbit

The smallest planet and the closest to the Sun. With no atmosphere, it swings from +430 °C by day to -180 °C at night.

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