1443 Ruppina, provisional designation 1937 YG, is a carbonaceous asteroid from the outer region of the asteroid belt, about 17 kilometers in diameter, while others derive a much larger size of 32 kilometers.[3] It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 29 December 1937.[10]
The asteroid orbits the Sun at a distance of 2.7–3.1 AU once every 5 years (1,838 days). Its orbit shows an eccentricity of 0.06 and is tilted by 2 degrees to the plane of the ecliptic. It has a rotation period of 5.9 hours[8] and an albedo of 0.18–021, based on observations by the Akari and WISE/NEOWISE missions.[5][6] The Collaborative Asteroid Lightcurve Link (CALL) considers the body to be a much darker C-type asteroid with an albedo of only 0.05, which consequently leads to a much higher derived figure for its diameter.[3]
The asteroid is named after the city of Ruppin, Germany, the birthplace of astronomer Martin Ebell, who proposed the name and after whom the minor planet 1205 Ebella is named.[2]
