(336756) 2010 NV1

(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.[lower-alpha 1]

    Discovery

    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]

    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

    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]

    Numbering and naming

    This minor planet was numbered by the Minor Planet Center on 31 August 2012.[7] As of 2018, it has not been named.[2]

    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.[6]
