2018 AG37

2018 AG37 (nicknamed FarFarOut) is a distant trans-Neptunian object that was discovered 132.2 ± 1.5 AU (19.78 ± 0.22 billion km) from the Sun, farther than any other currently observable known object in the Solar System. Imaged in January 2018 during a search for the hypothetical Planet Nine, the confirmation of this object was announced in a press release in February 2021 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo. The object was nicknamed "FarFarOut" to emphasize its distance from the Sun. With an estimated diameter of 400 km (250 mi), it is near the lower limit for a dwarf planet candidate.
