abs_magnitude = 6.4mp|2004 VN|112, also written as 2004 VN112, is an Extended Scattered disc object (detached object) since it has perihelion greater than 40 AU and
semi-major axis greater than 200 AU. It never gets closer than 47 AU from the Sun (about the outer edge of the mainKuiper belt ) and averages being more than 300 AU from the Sun. Its large eccentricity strongly suggests that it was gravitationally scattered onto its current orbit. Since all detached objects are outside of the current influence ofNeptune , how it came to have this orbit can not yet be explained. It has only been observed 19 times over 3 oppositions. Evendwarf planet candidate90377 Sedna has only been observed 64 times.cite web

url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=Sedna
accessdate=2008-02-28] Both Sedna and mpl|2000 CR|105 have similar orbits (perihelion greater than 40 AU and semi-major axis greater than 200 AU).References
