    1712 Angola, provisional designation 1935 KC, is a dark asteroid from the outer main-belt, discovered by English-born South African astronomer Cyril Jackson at Johannesburg Observatory on May 28, 1935.[9] The asteroid measures about 60 kilometers in diameter. Its orbit is tilted by more than 19 degrees towards the ecliptic plane.[1]

    The C-type asteroid orbits the Sun at a distance of 2.7–3.6 AU once every 5 years and 8 months (2,059 days). It has a rotation period of 11.53 hours and an albedo in the range of 0.03–0.05, according to the IRAS, Akari, WISE and NEOWISE surveys.[4][5][6][7]

    It is named after Angola, the state on the southwestern coast of Africa.[2]
