8373 Stephengould (1992 AB) is anouter main-beltbinary asteroid[5] discovered on 1 January 1992 byCarolyn S. Shoemaker andEugene Merle Shoemaker atPalomar Observatory.[1] The asteroid was named after theHarvard paleontologistStephen Jay Gould. The asteroid has a very high inclination, having the second highest inclination of any of the first 10,000 discovered asteroids in the asteroid belt, after2938 Hopi.
Stephengould is one of few strongly unstable asteroids located near the 2:1mean motion resonance with the gas giantJupiter, that corresponds to one of the prominentKirkwood gaps in the asteroid belt.[3]
The asteroid has a moon orbiting it, discovered in 2010 with an orbital period of 1 day, 10 hours, and 9 minutes.[5]
