    (574372) 2010 JO179 (provisional designation 2010 JO179) is a large, high-order resonant trans-Neptunian object in the outermost regions of the Solar System, approximately 700 kilometers (430 miles) in diameter. [6] Long-term observations suggest that the object is in a meta-stable 5:21 resonance with Neptune. [6] Other sources classify it as a scattered disc object. [4] [5] It is possibly large enough to be a dwarf planet. [6]

    The Minor Planet Center credits the object's first official observation on 10 May 2010 to Pan-STARRS ( F51 ) at Haleakala Observatory, Hawaii, United States. [1] [2] The observations were made by Pan-STARRS'Outer Solar System Survey. [6] There are 4 February 1951 precovery images from the Palomar Observatory Sky Survey, extending the observation arc by approximately 60 years. [1] The precovery images are from the same year the object came to perihelion (closest approach to the Sun).

    2010 JO179 orbits the Sun at a distance of 39.6–118  AU once every 699 years and 5 months (semi-major axis of 78.8 AU). Its orbit has a high eccentricity of 0.50 and an inclination of 32° with respect to the ecliptic. [3]

    Numbering and naming

    This minor planet was numbered by the Minor Planet Center on 10 August 2021, receiving the number (574372) in the minor planet catalog ( M.P.C. 133504). [9] As of 2021, it has not been named. [1]

    Physical characteristics

    Photometry

    Photometric observations of 2010 JO179 gave a monomodal lightcurve with slow rotation period of 30.6 hours, suggesting a rather spherical shape with significant albedo patchiness. An alternative period solution of a bimodal lightcurve is considered less likely. It would double the period and imply an ellipsoidal shape with an axis-ratio of at least 1.58. [6]

    Diameter and albedo

    The object's mean diameter has been estimated to measure 574 and 735 kilometers, with an assumed albedo of 0.09, by Michael Brown and the Johnston's Archive respectively, [4] [8] while the discoverers estimate a diameter of 600–900 kilometers with an estimated albedo of 0.21 to 0.07. [6]
