2014 UZ224 is a trans-Neptunian object and possible dwarf planet orbiting in the scattered disc of the outermost Solar System.

[7][8] 2014 UZ224 was discovered by a team led by David Gerdes using data collected by the large camera Dark Energy Camera (DECam).

[9][10] It has a diameter of ~635 km (395 mi) and reflects just 13 percent of the sunlight that hits it.

[3][2] Since the numbering of (532037) 2013 FY27 in May 2019, 2014 UZ224 may be the largest unnumbered object in the Solar System as of July 2024 (though see 2012 VP113).

[4] The earliest known precovery observations of 2014 UZ224 were taken at the Mauna Kea Observatory on 15 October 2006.
