(24952) 1997 QJ4, also written as 1997 QJ4, is a plutino and as such, it is trapped in a 2:3 mean-motion resonance with Neptune. It was discovered on 28 August 1997 by Jane X. Luu, Chad Trujillo, David C. Jewitt and K. Berney. This object 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 moves in a relatively eccentric orbit (0.224). It has an estimated diameter of 139 km; therefore, it is unlikely to be classified as a dwarf planet.
