2000 CR105

The comet known as 2000 CR105 is the second most distant known object in the solar system after 90377 Sedna. It circles the sun in a highly eccentric orbit every 3175 years at an average distance of 224 astronomical units (equal to the earth sun distance or about 150 million kilometers). 2000 CR105 and Sedna differ from other Scattered Disk objects in that at their perihelion distances 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 theory states that they were pulled from their original positions by a passing star or a very distant and undiscovered giant planet.
