2023 Asaph, provisional designation 1952 SA, is a carbonaceous asteroid in the outer regions of the main-belt, about 21 kilometers in diameter.[6] It was discovered on September 16, 1952 by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[10]
The asteroid orbits the Sun at a distance of 2.1–3.7 AU once every 4 years and 10 months (1,782 days) and its relatively eccentric orbit is tilted by 22 degrees to the plane of the ecliptic.[1] Depending on different observations, it takes between 3.9 and 9.2 hours to rotate once around its axis. The C-type asteroid has a geometric albedo of nearly 0.10.[4][5]
It was named in memory of Asaph Hall (1829–1907), who discovered the Martian satellites, Phobos and Deimos.[2]
