2000 CR105 is the third most distant known object in the solar system after 2003 UB313 and 90377 Sedna. It circles the sun in a highly eccentric orbit every 3175 years at an average distance of 224 astronomical units (1 A.U. being equal to the mean earth-sun distance of about 150 million kilometers). 2000 CR105 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 theory states that they were pulled from their original positions by a passing star or a very distant and undiscovered giant planet. 2003 UB313 (also written 2003 UB313) is a trans-Neptunian object (TNO) which California astronomers at Mount Palomar observatory describe as definitely bigger than the planet Pluto. ... 90377 Sedna is a trans-Neptunian object, discovered by Michael Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale University) on November 14, 2003. ...

The comet known as 2000CR105 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 (1 A.U. being equal to the mean earth-sun distance of about 150 million kilometers).
2000CR105 and Sedna differ from other Scattered Disk objects in that at their perihelion distances are not within the gravitational influence of the planet Neptune.
