The asteroid was discovered on 1 April 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. DescriptionCarpenter is a member of the Eos family ({{small|606}}), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[3][9]{{rp|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.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] References1. ^1 2 {{cite book |title=Dictionary of Minor Planet Names – (1852) Carpenter |last=Schmadel |first=Lutz D. |publisher=Springer Berlin Heidelberg |pages=148–149 |date=2003 |isbn=978-3-540-29925-7 |doi=10.1007/978-3-540-29925-7_1853 |chapter = (1852) Carpenter}} [1][2][3][4]2. ^1 2 {{Cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
