(248835) 2006 SX368 /əˈkɪr./, also known as 2006 SX368, is a centaur orbiting in the outer Solar System between Saturn and Neptune. It was discovered on September 30, 2006 by A. C. Becker, A. W. Puckett and J. Kubica.

Orbit[edit]

Centaurs have short dynamical lives due to strong interactions with the giant planets. The orbit of 2006 SX368 is unusually eccentric — near the perihelion it comes under influence of Uranus, while at the aphelion it travels slightly beyond the orbit of Neptune.[3]

Physical characteristics[edit]

In 2010, thermal flux from 2006 SX368 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 kilometres (43 mi) to 80 kilometres (50 mi).[3]
