2023 Asaph
2023 Asaph, provisional designation 1952 SA, is a carbonaceous asteroid in the outer regions of the main-belt, about 21 kilometers in diameter.〔 It was discovered on September 16, 1952 by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn in the U.S state of Indiana.〔 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.〔 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.〔〔
It was named in memory of Asaph Hall (1829–1907), who discovered the Martian satellites, Phobos and Deimos.〔
