(307463) 2002 VU130 (provisional designation 2002 VU130) is a trans-Neptunian object, located in the circumstellar disc of the Kuiper belt in the outermost region of the Solar System. The resonant trans-Neptunian object belongs to the population of plutinos and measures approximately 253 kilometers (160 miles) in diameter. It was discovered on 7 November 2002, by American astronomer Marc Buie at the Kitt Peak Observatory near Tucson, Arizona. The object has not been named yet.[1]

Orbit and classification

[edit]

2002 VU130 is a plutino, a population of objects in the Kuiper belt that stay in a 2:3 resonance with Neptune.[4][5] A large part of the inner Kuiper belt is formed by objects belonging to this population which is named after its largest member, Pluto. 2002 VU130 orbits the Sun at a distance of 30.9–47.1 AU once every 243 years and 9 months (89,021 days; semi-major axis of 39.02 AU). Its orbit has an eccentricity of 0.21 and an inclination of 1° with respect to the ecliptic.[3] The body's observation arc begins with its official discovery observation on 7 November 2002.[1] It is currently approaching the Sun at 39.428 AU,[7] with its perihelion-passage projected to occur in June 2076.[3]

Numbering and naming

[edit]

This minor planet was numbered by the Minor Planet Center on 10 December 2011 (M.P.C. 77418).[8] As of 2021, it has not been named.[1] If named, it will follow the already established scheme of naming these objects after mythological entities associated with the underworld.

Physical characteristics

[edit]

Diameter and albedo

[edit]

Observations with Herschel's PACS instrument were published in 2011. For 2002 VU130, the measurements gave a mean-diameter of 252.9+33.6
−31.3
 km
with an unusually high albedo of 0.179+0.202
−0.103
and an absolute magnitude of 5.47±0.83.[6] This result has been adopted in Johnston's Archive, giving a rounded diameter of 253 kilometers (160 miles),[5] while Mike Brown estimates as similar one of 260 km with an albedo of 0.18 and an absolute magnitude of 5.5.[9]
