1443 Ruppina

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.〔 It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 29 December 1937.〔
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〔 and an albedo of 0.18–021, based on observations by the Akari and WISE/NEOWISE missions.〔〔 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.〔
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.〔
