[10] In April 2008, a rotational lightcurve of Katanga was obtained from photometric observations by American astronomer Brian D. Warner at his Palmer Divide Observatory in Colorado.
[9] The quality of this result supersedes two periods previously obtained by astronomers Stefano Sposetti and Glenn Malcolm in May and June 2001, respectively (U=2/2).
[7][8] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Katanga measures between 9.76 and 15.90 kilometers in diameter, and its surface has an albedo between 0.133 and 0.353.
[4][5][6] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.242 and a diameter of 16.28 kilometers with an absolute magnitude of 11.1.
[3] This minor planet was named after the Katanga Province, a rich mining region in the Democratic Republic of the Congo in Central Africa.
