Rhea — moon orbiting Saturn, shown live in Cosmoscope, a real-time 3D map of the universe.
A quiet, heavily cratered ice world — possibly with the only ring system ever suspected around a moon.
Cosmoscope puts Rhea 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 Rhea 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 Rhea where it was on any past date, or where it will be years from now.
