Uni — trans-Neptunian object, shown live in Cosmoscope, a real-time 3D map of the universe.
A Kuiper Belt riddle: it and its moon are so under-dense they appear to be mostly porous ice and rubble.
Cosmoscope puts Uni 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 Uni 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 Uni where it was on any past date, or where it will be years from now.
