(336756) 2010 NV1, provisional designation 2010 NV1, is a highly eccentric planet crossing trans-Neptunian object, approximately 44 kilometers 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[edit]

This 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.[2]

Orbit[edit]

2050 563 AU 4830 yrs

2010 NV1 came to perihelion in December 2010 at a distance of 9.4 AU from the Sun.[1] As of 2016, it is 14 AU from the Sun.[5]

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]

Physical characteristics[edit]

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.[4]

Naming[edit]

As of 2017, this minor planet remains unnamed.[2]

Notes[edit]

  1. ^ a b c d e 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.[6]
