(248835) 2006 SX368

' (provisional designation ') is a centaur, approximately 75 km in diameter, orbiting in the outer Solar System between Saturn and Neptune. It was discovered on 16 September 2006, by American astronomers Andrew Becker, Andrew Puckett, and Jeremy Kubica at Apache Point Observatory in Sunspot, New Mexico.

Orbit and classification
Centaurs are dynamically unstable due to strong interactions with the giant planets. The orbit of is unusually eccentric — near its perihelion, it comes under the influence of Uranus, while at the aphelion it travels slightly beyond the orbit of Neptune.

It orbits the Sun at a distance of 11.9–32.0 AU once every 103 years and 2 months (37,683 days; semi-major axis of 22.0 AU). Its orbit has an eccentricity of 0.46 and an inclination of 36° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at Apache Point in September 2006.

Physical characteristics
In 2010, thermal flux from in the far-infrared was measured by the Herschel Space Telescope. As a result, its equivalent size was estimated to lie within a range from 70 km to 80 km.
