2014 UZ224 is a large trans-Neptunian object orbiting in the scattered disc of the outermost Solar System. As of 2021[update], it is approximately 89.7 AU (13.42 billion km) 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".[6][7]
2014 UZ224 was discovered by a team led by David Gerdes using data collected by the large camera Dark Energy Camera (DECam).[8][9] 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 Chiminigagua in May 2019, 2014 UZ224 may be the largest unnumbered object in the Solar System as of July 2024 (though see 2012 VP113).[10] The earliest known precovery observations of 2014 UZ224 were taken at the Mauna Kea Observatory on 15 October 2006.[4]
