365 Corduba is a very large main-belt asteroid that was discovered by the French astronomer Auguste Charlois on March 21, 1893 from Nice. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado during 2007 gave a light curve with a period of 6.551 ± 0.002 hours and a brightness variation of 0.05 in magnitude. This differs somewhat from a 2004 study that gave a period of 6.354 hours, but this difference may be explained by the small magnitude variation which tends to increase the randomizing effect of noise in the data.[3]
