Seeing Umbriel in real time

Cosmoscope puts Umbriel at its true position in the solar system, computed from JPL-derived ephemeris and updated continuously. Open the live 3D view to see, in real time, how far Umbriel is from the Sun and from Earth right now, how many minutes or hours light takes to cross that gap, and how fast it is moving along its orbit. Scrub the timeline to place Umbriel where it was on any past date, or where it will be years from now.
