1203 Nanna, provisional designation 1931 TA, is a dark and eccentric asteroid from the outer region of the asteroid belt, about 35 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 5 October 1931.[10]
The carbonaceous C-type asteroid orbits the Sun at a distance of 2.2–3.6 AU once every 4 years and 11 months (1,792 days). Its orbit shows an eccentricity of 0.25 and is tilted by 6 degrees to the plane of the ecliptic. It has a rotation period of about 18 hours[7] and an albedo in the range of 0.03–0.06, according to the surveys carried out by IRAS, Akari, and WISE/NEOWISE.[4][5][6]
The minor planet was named after Anna Risi, a model in several paintings by German classicist painter Anselm Feuerbach. [2]
