1818 Brahms, provisional designation Template:Mp, is an asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 15 August 1939, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany.[1] The asteroid was named after composer Johannes Brahms.[2]
Orbit and classification
Brahms orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 2 months (1,163 days). Its orbit has an eccentricity of 0.18 and an inclination of 3° with respect to the ecliptic.[3] Brahms was first identified as Template:Mp at the discovering observatory in 1904, extending the body's observation arc by 35 years prior to its official discovery observation.[1]
Physical characteristics
As of 2017, Brahms effective size, albedo and spectral type, as well as its rotation period and shape remain unknown. Based on a magnitude-to-diameter conversion, its generic diameter is between 5 and 11 kilometer for an absolute magnitude of 13.8, and an assumed albedo in the range of 0.05 to 0.25.[4] Since asteroids in the inner main-belt are typically of stony rather than carbonaceous composition, with albedos of 0.20 or higher, BrahmsTemplate:'s diameter can be estimate to measure around 6 kilometers, as the higher its albedo (reflectivity), the lower the body's diameter at a constant absolute magnitude (brightness).[4]
Naming
This minor planet is named for the German composer Johannes Brahms (1833–1897).[2] The official Template:MoMP was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3935Script error: No such module "Check for unknown parameters".).[5]
