Corduba (minor planet designation: 365 Corduba) is a very large main-belt asteroid that was discovered by the French astronomer Auguste Charlois on 21 March 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.[6]
