(336756) 2010 NV₁ (provisional designation 2010 NV₁) is a highly eccentric planet crossing trans-Neptunian object, also classified as 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.

Discovery

2010 NV₁ trans-Neptunian object 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.

Orbit and classification

2010 NV₁ orbits the Sun at a distance of 9.4–547.2 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. It came to perihelion in December 2010 at a distance of 9.4 AU from the Sun. As of 2021, it is 21.3 AU from the Sun. 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 (q_min) from the Sun.

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 31 August 2012 (M.P.C. 80287). As of 2021, it has not been named.

Physical characteristics

According to the surveys carried out by the NEOWISE mission, 2010 NV₁ measures 44.2 kilometers in diameter and its surface has a low albedo of 0.057. More recent published data gives an diameter of 52.2±4.5 kilometers with an albedo of 0.042.

Notes

1. ^ 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.
