Considered a detached object,Jewitt, David Morbidelli, Alessandro Rauer, Heike 2007 Trans-Neptunian Objects and Comets Saas-Fee Advanced Course 35 Swiss Society for Astrophysics and Astronomy Berlin Springer 978-3-540-71957-1 86Lykawka, Patryk Sofia Mukai, Tadashi July 2007 Dynamical classification of trans-Neptunian objects: Probing their origin, evolution, and interrelation Icarus 189 1 213–232 10.1016/j.icarus.2007.01.001 2007Icar..189..213L it orbits the Sun in a highly eccentric orbit every 3,305 years at an average distance of 222 astronomical units (AU). Description Mike Brown's website lists it with a diameter of 327 km mi based on an assumed albedo of 0.04. The albedo is expected to be low because the object has a blue (neutral) color. However, if the albedo is higher, the object could easily be half that size. 2000 CR 105 and Sedna differ from scattered-disc objects in that they are not within the gravitational influence of the planet Neptune even at their perihelion distances (closest approaches to the Sun). It is something of a mystery as to how these objects came to be in their current, far-flung orbits. Several hypotheses have been put forward: They were pulled from their original positions by a passing star.Scott J. Kenyon Benjamin C.

Matese Daniel P. Whitmire Jack J. Lissauer Jack J. Lissauer A wide-binary solar companion as a possible origin of Sedna-like objects Earth, Moon, and Planets 97 459 2005 They were pulled from their original positions by an undiscovered companion star orbiting the Sun such as Nemesis. They were captured from another planetary system during a close encounter early in the Sun's history. According to Kenyon and Bromley, there is a 15% probability that a star like the Sun had an early close encounter and a 1% probability that outer planetary exchanges would have happened. 2000 CR 105 is estimated to be 2–3 times more likely to be a captured planetary object than Sedna. 2000 CR 105 is the first object discovered in the Solar System to have a semi-major axis exceeding 150 AU, a perihelion beyond Neptune, and an argument of perihelion of 340 55 °. It may be influenced by Planet Nine. See also Planets beyond Neptune List of Solar System objects by greatest aphelion References 25em Marc W. Buie Marc W.
