    1031 Arctica, provisional designation 1924 RR, is a dark asteroid and slow rotator from the outer region of the asteroid belt, about 75 kilometers in diameter. It was discovered by Soviet−Russian astronomer Sergey Belyavsky at Simeiz Observatory on the Crimean peninsula on 6 June 1924.[10]

    The dark C-type asteroid is classified as a rather rare CX-subtype in the Tholen taxonomic classification scheme (also see list of CX-type asteroids). It orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 4 months (1,944 days). Its orbit is tilted by 18 degrees to the plane of the ecliptic and shows an eccentricity of 0.06. It has a long rotation period of 51 hours[8][9] and an albedo of 0.04–0.05, according to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5][6][7]

    The minor planet is named for the Arctic Sea,[2] located in the Northern Hemisphere and the smallest and shallowest of the world's five major oceanic divisions.
