9963 Sandage, provisional designation 1992 AN, is a stony Phocaea asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter.
It was discovered by American astronomer
Eleanor Helin at the Palomar Observatory in California on 9 January 1992, and later named after American astronomer Allan Sandage.[2][10]
Orbit and classification
Sandage is a
Crimea–Nauchnij in 1976, the body's observation arc begins at the German Karl Schwarzschild Observatory in 1989, or 3 years prior to its official discovery observation at Palomar.[10]
Physical characteristics

Two rotational
Diameter and albedo
According to the survey carried out by the
albedo of 0.16,[5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.23 – derived from the family's largest member and namesake, 25 Phocaea – and calculates a diameter of 5.5 kilometers with an absolute magnitude of 13.53.[3]
