    1481 Tübingia, provisional designation 1938 DR, is a carbonaceous asteroid from the outer region of the asteroid belt, about 35 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 7 February 1938.[10]

    The dark C-type asteroid orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 3 months (1,913 days). Its orbit shows an eccentricity of 0.05 and is tilted by 4 degrees to the plane of the ecliptic. It has a relatively long rotation period of 24 hours[8] and an albedo in the range of 0.08–0.12 according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7]

    The asteroid was named after Tübingen, city in southern Germany and birthplace of astronomer Johannes Kepler.[2]
