2023 Asaph, provisional designation 1952 SA, is a dark asteroid from the outer regions of the asteroid belt, approximately 21 kilometers in diameter.[6] It was discovered on 16 September 1952, by astronomers of the Indiana Asteroid Program at Goethe Link Observatory in Indiana, United States.[11]

Orbit and classification

Asaph orbits the Sun in the outer main-belt at a distance of 2.1–3.7 AU once every 4 years and 11 months (1,781 days). Its orbit has an eccentricity of 0.28 and an inclination of 22° with respect to the ecliptic.[1] The asteroid's observation arc begins with its official discovery observation Goethe Link.[11]

Physical characterization

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.09 and 0.1045.[4][5][6][7]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a larger diameter of 25.44 kilometers based on an absolute magnitude of 11.7.[3]
