2014 UZ224 is a trans-Neptunian object and possible dwarf planet orbiting in the scattered disc of the outermost Solar System. As of 2021, 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".

2014 UZ224 was discovered by a team led by David Gerdes using data collected by the large camera Dark Energy Camera (DECam). It has a diameter of ~635 km (395 mi) and reflects just 13 percent of the sunlight that hits it. 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). The earliest known precovery observations of 2014 UZ224 were taken at the Mauna Kea Observatory on 15 October 2006.

Orbit

It orbits the Sun once every approximately 1,100 years and is the second farthest object from the Sun with a stable orbit. Its perihelion is almost as close as Pluto’s aphelion and will reach it on the 22nd of May in 2142.

Numbering and naming

As of 2024, this minor planet has neither been numbered nor named by the Minor Planet Center.
