1852 Carpenter

1852 Carpenter, provisional designation 1955 GA, is an Eoan asteroid from the outer regions of the asteroid belt, approximately 20 kilometers in diameter. The asteroid was discovered on 1 April 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.

Description

Carpenter is a core member of the Eos family (606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[3][4][7]: 23  It orbits the Sun in the outer main-belt at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,913 days). Its orbit has an eccentricity of 0.06 and an inclination of 11° with respect to the ecliptic.[5]

This minor planet was named after American astronomer Edwin Francis Carpenter (1898–1963), second director of the Steward Observatory who researched spectroscopic binaries and interacting galaxies. He played a major role in enabling the construction of the Kitt Peak National Observatory.[2] The official naming citation was published by the Minor Planet Center on 1 April 1980 (M.P.C. 5282).[8]
