DeeDee — trans-Neptunian object, explore its interactive 3D model in Cosmoscope.
Explore DeeDee in a live 3D Solar System. Follow its calculated motion and inspect real astronomical data, distances and orbital facts.
“Distant Dwarf” — a faint, far-flung world so remote its light takes over twelve hours to reach us.
Cosmoscope places DeeDee in the Solar System using astronomical ephemeris or orbital elements, updated for the simulation time. Explore its calculated motion, distance and orbital facts in the interactive 3D view. Accuracy depends on the orbital model and its valid time range.
