It was discovered by astronomers with the Canada–France Ecliptic Plane Survey at Mauna Kea Observatories, Hawaii, when it was near aphelion on 31 August 2003. Orbit and classification thumb|left|220px|Orbital diagram of 2003 QX 113 2003 QX 113 orbits the Sun at a distance of 37.7–62.2 AU once every 353 years and 1 month (128,966 days; semi-major axis of 49.96 AU). Its orbit has an eccentricity of 0.25 and an inclination of 7° with respect to the ecliptic. 2003 QX 113 last came to perihelion around 1882, moving away from the Sun ever since and is currently about 60.5 AU from the Sun, and will reach its aphelion around 2058. It is classified as a scattered disc object, or "near-scattered" object in the classification of the Deep Ecliptic Survey, that still gravitationally interacts with Neptune (30.1 AU) due to its relatively low perihelion of 37.7 AU, contrary to the extended-scattered/detached objects and sednoids which never approach Neptune as close. It has also been described as a "detached classical belt object" by the discovering Canada–France Ecliptic Plane Survey (CFEPS), that are objects with a semi-major axis beyond the 2:1 mean-motion resonance (i.e. beyond the twotino population at 47.8 AU) and with an eccentricity larger than 0.24.4 It was the furthest object discovered in the CFEPS.8 Physical characteristics Based on a generic magnitude-to-diameter conversion, 2003 QX 113 measures approximately 423 km mi off 2 us in diameter, for an assumed albedo of 0.9 and a magnitude of 5.1. 2021, no rotational lightcurve for this object has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown. See also (148209) 2000 CR 105 References 30em 2017-10-23 last obs.
