 is a trans-Neptunian object and possible dwarf planet orbiting in the scattered disc of the outermost Solar System. , it is approximately 89.7 AU from the Sun, and will slowly decrease in distance until it reaches its perihelion of 38 AU in 2142. The discoverers have nicknamed it "DeeDee" for "Distant Dwarf".

was discovered by a team led by David Gerdes using data collected by the large camera Dark Energy Camera (DECam).
