    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).
