DeeDee — trans-Neptunian object, shown live in Cosmoscope, a real-time 3D map of the universe.
“Distant Dwarf” — a faint, far-flung world so remote its light takes over twelve hours to reach us.
Cosmoscope puts DeeDee 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 DeeDee 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 DeeDee where it was on any past date, or where it will be years from now.
