    1035 Amata, provisional designation 1924 SW, is a large, carbonaceous asteroid from the outer region of the asteroid belt, about 51 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany on 29 September 1924.[12]

    The C-type asteroid orbits the Sun at a distance of 2.5–3.8 AU once every 5 years and 7 months (2,042 days). Its orbit shows an eccentricity of 0.19 and an inclination of 18 degrees from the plane of the ecliptic.[1]

    In 2002, a photometric light-curve analysis by American amateur astronomer Robert Stevens at the Santana Observatory (646) in California rendered a rotation period of 9.081±0.001 hours with a brightness amplitude of 0.44 in magnitude (U=3).[9] In the same month, another observation was made at the Oakley Observatory in the U.S. state of Indiana and gave a very similar period of 9.05±0.01 hours and a variation in brightness of 0.32 in magnitude (U=2).[10]

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's WISE with its subsequent NEOWISE mission, the asteroid has a low albedo in the range of 0.038 to 0.052 and a diameter between 50.7 and 62.2 kilometers.[4][5][6][7][8] The Collaborative Asteroid Lightcurve Link derived a diameter of 50.7 kilometers and an albedo of 0.057.[3]

    The asteroid was possibly named after Amata from Roman mythology, wife of King Latinus and a character in Virgil's Aeneid. She is also the mother of Lavinia, the wife of Aeneas, after whom 1172 Äneas, one of the largest Jupiter trojans, is named.[2]
