3674 Erbisbühl, provisional designation 1963 RH, is an stony asteroid and one of the largest Mars-crossers from the innermost regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by German astronomer Cuno Hoffmeister at his Sonneberg Observatory in Eastern Germany, on 13 September 1963.[7]
The stony S-type asteroid is classified as an Sk-subtype in the SMASS taxonomic scheme. It orbits the Sun at a distance of 1.5–3.2 AU once every 3 years and 8 months (1,325 days). Its orbit shows a high eccentricity of 0.38 and an inclination of 21 degrees from the plane of the ecliptic.[1]
A photometric light-curve analysis at the U.S. Antelope Hills Observatory in 2003, rendered a rotation period of 11.28±0.01 hours with a brightness amplitude of 0.40 in magnitude.[5] According to the survey carried out by the Japanese Akari satellite, the asteroid has a high albedo of 0.249 with a corresponding diameter of 10.3 kilometers,[4] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.20 and calculates a diameter of 11.8 kilometers.[3]
The minor planet was named for the mountain on which the Sonneberg Observatory is located (also see 1039 Sonneberga). The discoverer, Cuno Hoffmeister, who founded the observatory, lived and worked there for many decades.[2]
