of 43.5 AU). Its orbit has an eccentricity of 0.03 and an inclination of 13 ° with respect to the ecliptic. It orbits slightly outside a 3:5 resonance with Neptune, taking 16 years (5.5% of its orbit) longer to orbit the Sun than a body in 3:5 resonance. Precovery observations exist dating back to 2006 in SDSS data.
