    2014 UZ224 is a trans-Neptunian object (TNO) and possible dwarf planet orbiting in the scattered disc. As of October 10, 2016, it is approximately 91.6 AU from the Sun, and will slowly decrease in distance until it reaches its perihelion of 38 AU sometime near 2142. Currently 2014 UZ224 is the third furthest known observable Solar System object from the Sun, after Eris (96.2 AU) and V774104 (~103 AU). In the media it has been nicknamed DeeDee for Distant Dwarf.[3][4]

    2014 UZ224 was discovered using the Dark Energy Camera (DECam).[5][6]
