(24952) 1997 QJf, also written as 1997 QJ4 is a 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. It was discovered on 1997-08-28 by Jane X. Luu, Chad Trujillo, David C. Jewitt and K. Berney.
