8373 Stephengould (1992 AB) is an outer main-belt binary asteroid[4] discovered on January 1, 1992 by Carolyn S. Shoemaker and Eugene Merle Shoemaker at Palomar.[1] The asteroid was named after the Harvard paleontologist Stephen 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, after 2938 Hopi.
This is a member of the Griqua family of asteroids that share similar orbital elements.[5] It is one of very few asteroids located in the 2 : 1 mean motion resonance with Jupiter.[6]
The asteroid has a moon orbiting it, discovered in 2010 with an orbital period of 1 day, 10 hours, and 9 minutes.[4]
