1817 Katanga, provisional designation 1939 MB, is a stony asteroid in from the inner regions of the asteroid belt. It was discovered by English-born South African astronomer Cyril Jackson at Johannesburg Union Observatory, South Africa on 20 June 1939.[10] It belongs to the small group of asteroids of the Phocaea family and measures about 16 kilometers in diameter, although observations from the Akari satellite gave a much lower size.[3][4][5][6]
The S-type asteroid orbits the Sun at a distance of 1.9–2.8 AU once every 3 years and 8 months (1,334 days). Its eccentric orbit is inclined by 26 degrees to the ecliptic plane.[1] Katanga has a rotation period between 6.3 and 8.5 hours, depending on different measurements[7][8][9] and a relatively high geometric albedo of 0.34,[5][6] despite seemingly inaccurate data from older observations made by the Infrared Astronomical Satellite, IRAS.[4]
The asteroid was named after the Katanga Province, a rich mining region in the Democratic Republic of the Congo, Africa.[2]
