Meet “DeeDee”, a Distant Dwarf in the Outer Solar System
Located 92 AU from the Sun, DeeDee is the second most distant trans-Neptunian object known — only the dwarf planet Eris is further away. Discovered in the Dark Energy Survey, which is being carried out at CTIO, DeeDee is petite, with a diameter ¼ that of Pluto. DeeDee was discovered by an international team, including NOAO astronomers Alistair Walker and Tim Abbott.
