Definitions for "(24952) 1997 QJ4"
QJf, also written as 1997 QJ4 is as plutino, so it has a 2:3 resonance with Neptune, similar to Pluto. It has a perihelion (closest approach to the Sun) at 30.463 AU and an aphelion (farthest approach from the Sun) at 48.038 AU, so it is in a relatively eccentric orbit. It has a diameter of 139 km, so it is unlikely to be classified as a dwarf planet.
