(15807) 1994 GV9 (provisional designation1994 GV9) is atrans-Neptunian object from the classicalKuiper belt located in the outermost region of theSolar System. Thecubewano belongs to the orbitally unexcitedcold population.[6] It was discovered on 15 April 1994, by astronomersDavid Jewitt andJun Chen at theMauna Kea Observatories, nearHilo, Hawaii.
As of 2018[update], it is 43.3AU from the Sun.[7] Currently, the closest approach possible to Neptune (MOID) is 11.2 AU (1.68 billion km).[1] Very little is known about the object. Based on the brightness and distance, it is estimated to be between 100 and 150 km in diameter depending on thealbedo.
1994 GV9 is the secondcubewano to be given an officialMinor Planet Center catalog number.[2] The first cubewano is15760 Albion.
