1852 Carpenter, provisional designation 1955 GA, is a main-belt asteroid which was discovered on 1 April 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. It orbits the Sun at a distance of 2.8–3.2 AU every 5.24 years and measures about 23 kilometers in diameter.[1]
The asteroid 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]
