1039 Sonneberga, provisional designation 1924 TL, is a dark asteroid from the middle region of the asteroid belt, about 35 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 24 November 1924.[9]
The X-type asteroid orbits the Sun at a distance of 2.5–2.8 AU once every 4.39 years (1,603 days). Its orbit shows an eccentricity of 0.06 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 34.2 hours[8] and an geometric albedo of about 0.04, according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7]
The minor planet was named for the city of Sonneberg, Thuringia in Germany and location of the Sonneberg Observatory.[2] It was founded in 1925 by astronomer Cuno Hoffmeister after whom the minor planets 1726 Hoffmeister and 4183 Cuno are named.
