Overview of (24952) 1997 QJ4
(24952) 1997 QJ4 is a plutino, a type of trans-Neptunian object that is part of a 2:3 mean-motion resonance with Neptune. This celestial body was discovered on August 28, 1997, by a team of astronomers including Jane X. Luu, Chad Trujillo, David C. Jewitt, and K. Berney.
Orbit and Characteristics
The orbit of (24952) 1997 QJ4 is relatively eccentric, with a perihelion (closest approach to the Sun) at 30.463 AU and an aphelion (farthest approach from the Sun) at 48.038 AU, resulting in an eccentricity of 0.224. The estimated diameter of this object is approximately 139 km, which makes it unlikely to achieve classification as a dwarf planet.
Scientific Significance
This object is important for the study of the trans-Neptunian region and provides insights into the dynamics of objects influenced by larger bodies such as Neptune.
