1359 Prieska, provisional designation 1935 OC, is a rare-type carbonaceous asteroid from the outer region of the asteroid belt, about 52 kilometers in diameter. It was discovered by English-born South-African astronomer Cyril Jackson at the Union Observatory, Johannesburg, on 22 July 1935.[5]
The dark C-type asteroid is classified as a rather rare CX-subtype in the Tholen taxonomy (also see list of CX-type asteroids). It orbits the Sun at a distance of 2.9–3.3 AU once every 5 years and 6 months (2,017 days). Its orbit shows an eccentricity of 0.07 and is tilted by 11 degrees to the plane of the ecliptic. According to the survey carried out by the Wide-field Infrared Survey Explorer, it has an albedo of 0.04, while the Collaborative Asteroid Lightcurve Link derives a slighly larger value of 0.05.[3][4] The body's rotation period remains unknown.
The minor planet was named in honour of Prieska, a town on the south bank of the Orange River, in the province of the Northern Cape, in western South Africa.[2]
