1359 Prieska, provisional designation 1935 OC, is a rare-type carbonaceous asteroid from the outer region of the asteroid belt, approximately 50 kilometers in diameter. It was discovered on 22 July 1935, by English-born South-African astronomer Cyril Jackson at Johannesburg Observatory in South Africa.[9]

Prieska is a dark C-type asteroid and classified as a rather rare CX:-subtype in the Tholen taxonomy (also see list of CX-type asteroids). It orbits orbits the Sun at a distance of 2.9–3.3 AU once every 5 years and 6 months (2,012 days). Its orbit has an eccentricity of 0.07 and an inclination of 11° with respect to the ecliptic.[1] In 1903, Prieska was first identified as A903 UE at Heidelberg Observatory, extending the body's observation arc by 32 years prior to its official discovery at Johannesburg.[9]

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Prieska measures between 36.45 and 65.86 kilometers in diameter, and its surface has an albedo between 0.03 and 0.07.[4][5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0494 and a diameter of 52.07 kilometers, based on an absolute magnitude of 10.3.[3] As of 2017, the body's rotation period remains unknown.[3]

This minor planet was named for the South African town of Prieska, located on the south bank of the Orange River, in the province of the Northern Cape.[2] Naming citation was first mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 123).[2]
