3043 San Diego, provisional designation 1982 SA, is a stony Hungaria asteroid and slow rotator from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter.
It was discovered by American astronomer
Eleanor Helin on 30 September 1982, at the U.S. Palomar Observatory in California, and named for the city of San Diego.[2][3]
Classification and orbit
The bright
Crimea–Nauchnij in 1974, extending the asteroid's observation arc by 8 years prior to its discovery.[3]
Slow rotator
San Diego is a
U=0).[8] This previously published period was only preliminary and is now considered wrong upon re-examination.[4]
Diameter and albedo
According to the survey carried out by the
NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, San Diego measures 4.8 and 5.0 kilometers in diameter and its surface has an albedo of 0.25 and 0.28, respectively,[6][7] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.30 – a compromise value between 0.4 and 0.2, corresponding to the Hungaria asteroids both as family and orbital group – and calculates a diameter of 4.6 kilometers with an absolute magnitude of 13.7.[4]
