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 90.8 AU from the Sun, slowly decreasing in distance until its closest point to the Sun of 38 AU sometime near 2142. Currently the orbit is very uncertain, but it is nevertheless well-known enough to make 2014 UZ224 the third furthest known solar system object from the Sun, after Eris (96.2 AU) and V774104 (~103 AU).
