Considered a detached object, it orbits the Sun in a highly eccentric orbit every 3305 years at an average distance of 222 astronomical units (AU).Mike Brown's website lists it as a possible dwarf planet with a diameter of 328 kilometres (204 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.(148209) 2000 CR105 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. They were pulled from their original positions by a very distant, and as-yet-undiscovered (albeit unlikely), giant planet. They were pulled from their original positions by an undiscovered companion star orbiting the Sun. 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. (148209) 2000 CR105 is estimated to be 2–3 times more likely to be a captured planetary object than Sedna.(148209) 2000 CR105 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 is one of five objects known with a semi-major axis greater than 100 AU and perihelion beyond 42 AU. It may be influenced by Planet Nine."@en }
