    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. [1]

    Orbital evolution
    Epoch Aphelion [lower-alpha 1] Orbital period
    1950561 AU4820 yrs
    2050563 AU4830 yrs

    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. [2] It came to perihelion in December 2010 at a distance of 9.4 AU from the Sun. [2] As of 2021, 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 2021, it has not been named. [1]

    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. [5] More recent published data gives an diameter of 52.2±4.5 kilometers with an albedo of 0.042. [4] [6]

    Notes

    1. 1 2 3 4 5 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.
