2010 KZ39 orbits the Sun at a distance of 42.9–47.8 AU once every 305 years and 3 months (111,504 days), similar to Makemake, Chaos and other bodies that circle the Sun in 6:11 resonance to Neptune. Its orbit has an eccentricity of 0.05 and an inclination of 26° with respect to the ecliptic.
Using the best-fit values for its orbit, it is expected to come to perihelion in 2109.[4] It has been observed 28 times over 3 oppositions and has an uncertainty parameter of 5.[1] As of 2016, is 46.1 AU from the Sun.[11] The body's spectral type as well as its rotation period remain unknown.
Brown assumes an albedo of 0.09 and magnitude of 4.5, resulting in an estimated diameter of 574 kilometers.[10] However, because the albedo is unknown and it a currently estimated absolute magnitude of 4.03±0.01,[9] its diameter could easily fall between 414 and 933 km[8] for an assumed albedo between 0.25 and 0.05, respectively.
