Orbit and classification. orbits the Sun at a distance of 50.2–158.9 AU once every 1069 years; semi-major axis of 104.53 AU. Its orbit has an eccentricity of 0.52 and an inclination of 43.16° with respect to the ecliptic. On the other hand, this TNO is not an extreme trans-Neptunian object as these objects generally have higher perihelia and/or higher eccentricities. Instead, it is located in a virtually unpopulated region at a perihelion of 50 AU and an eccentricity of 0.5 "(see adjunct images, where the grid crosses at q50 AU and "e"0.5)" The Kozai mechanism  is capable of transferring orbital eccentricity to a higher inclination. It can be speculated that this dynamical phenomenon also affected the orbit of . If this was the case, and the object had once belonged to the extreme detached disc objects – which have eccentricities above 0.8 and semi-major axes of at least 250 AU, for a perihelion of 50 AU – the Kozai effect would have slowly decreased s aphelion from over 450 AU to currently 159 AU while increasing its inclination. seems to belong to the same group as . Physical characteristics. Diameter and albedo. Based on an absolute magnitude of  5.4, and an assumed astronomical albedo of 0.9, which is a standard default value adopted for trans-Neptunian objects by Johnston's archive, "" measures approximately in diameter. The body's color, rotation period, pole and shape remain unknown.
