(336756) 2010 NV1
Trans-Neptunian object
From Wikipedia, the free encyclopedia
(336756) 2010 NV1 (provisional designation 2010 NV1) is a highly eccentric planet crossing trans-Neptunian object, also classified as a centaur and damocloid, approximately 52 kilometers (32 miles) in diameter. It is on a retrograde cometary orbit. It has a barycentric semi-major axis (average distance from the Sun) of approximately 286 AU.[a]

Discovery
2010 NV1 was discovered on 1 July 2010, by NASA's space-based Wide-field Infrared Survey Explorer (WISE). It was first observed by the Mount Lemmon Survey in 2009, extending the body's observation arc by 8 months prior to its official discovery observation by WISE.[1]

2010 NV1 orbits the Sun at a distance of 9.4â547.2 AU once every 4643 years and 5 months (1,696,004 days; semi-major axis of 278.33 AU). Its orbit has an eccentricity of 0.97 and an inclination of 141° with respect to the ecliptic.[2] It came to perihelion in December 2010 at a distance of 9.4 AU from the Sun.[2] As of 2021[update], it is 21.3 AU from the Sun.[8] It will not be 50 AU from the Sun until late 2044. After leaving the planetary region of the Solar System, 2010 NV1 will have a barycentric aphelion of 563 AU with an orbital period of 4830 years. In a 10 million year integration of the orbit, the nominal (best-fit) orbit and both 3-sigma clones remain outside 7.7AU (qmin) from the Sun.[3]
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 31 August 2012 (M.P.C. 80287).[10] As of 2025[update], it has not been named.[1]
Physical characteristics
Notes
- Given the orbital eccentricity of this object, different epochs can generate quite different heliocentric unperturbed two-body best-fit solutions to the semi-major axis and orbital period. For objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. Using JPL Horizons, the barycentric semi-major axis is approximately 286 AU.[9]
