It is one a small number of detached objects with perihelion distances of 30 AUs or more, and semi-major axes of 200 AU or more.[1] Such objects can not reach such orbits without some perturbing object, which lead to the speculation of Planet Nine.
A search of SDSS images of the region 2003 SS422 would have been in 2001 turned up no conclusive detections of the asteroid, indicating it is either much dimmer than expected, or on a very different orbit.
