1130 Skuld, provisional designation 1929 RC, is a stony asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered on 2 September 1929 by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany.[10] The body was independently discovered by astronomers and fellow countrymen Arnold Schwassmann and Arno Wachmann at the Hamburger Bergedorf Observatory ten nights later.[2]
The asteroid is a member of the Flora family, a large group of rocky S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,215 days). Its orbit shows a notable eccentricity of 0.20 and is tilted by 2 degrees to the plane of the ecliptic. It has a rotation period of 4.8 hours[lower-alpha 1][9] and an albedo in the range of 0.20 to 0.30, according to the surveys carried out by the Japanese Akari satellite, the Wide-field Infrared Survey Explorer, and subsequent NEOWISE mission.[4][5][6] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24, which is typical for a stony asteroid.
The minor planet was named after Skuld, one of the three Norns in Norse mythology.[2]
