Ritona — trans-Neptunian object, shown live in Cosmoscope, a real-time 3D map of the universe.
A reddish classical KBO out beyond Neptune, one of many siblings on quiet, near-circular paths.
Cosmoscope puts Ritona 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 Ritona 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 Ritona where it was on any past date, or where it will be years from now.
