(148209) 2000 CR105

{{downsize|title=
'', also written as '(148209) 2000 CR105', is the fourth most distant known object in the solar system after Eris, and Sedna. It circles the sun in a highly eccentric orbit every 3240 years at an average distance of 219 astronomical units (1 AU being about equal to the mean Earth-Sun distance: roughly 150 gigametres).
has a diameter of around 265 km. This small size will probably prevent it from ever qualifying as a dwarf planet.
and Sedna differ from other scattered disc objects in that at their perihelion distances, they are not within the gravitational influence of the planet Neptune. It is something of a mystery how these objects came to be in their current far-flung orbits. One hypothesis posits that they were pulled from their original positions by a passing star or a very distant and as-yet-undiscovered (albeit unlikely) giant planet.
