    Orbit and classification

    2013 GP136 orbits the Sun at a distance of 41.1–268.5 AU once every 1925 years and 4 months (703,239 days). Its orbit has an eccentricity of 0.73 and an inclination of 33° with respect to the ecliptic.[1]

    It was mentioned in a 2016 paper by Malhotra of the Lunar and Planetary Laboratory, at The University of Arizona, Tucson, AZ as a detached object with a perihelion greater than 40 AUs, a 6:1 orbital period ratio with 90377 Sedna, and in a possible 9:1 mean-motion resonance with a hypothetical large Planet Nine.[5]
