(15807) 1994 GV9, also written (15807) 1994 GV9, is a trans-Neptunian object of the cubewano class. It is an "orbitally unexcited" cold member of the Classical Kuiper belt.[3] It was discovered on April 15, 1994, by David C. Jewitt and Jun Chen at the Observatories at Mauna Kea, near Hilo. As of 2018[update], it is 43.3 AU from the Sun.[7] Currently, the closest approach possible to Neptune (MOID) is 11.2 AU (1.68 billion km).[5] Very little is known about the object. Based on the brightness and distance, it is estimated to be between 100–150 km in diameter depending on the albedo.
(15807) 1994 GV9 is the second cubewano to be given an official Minor Planet Center catalog number.[2] The first cubewano is 15760 Albion.
