1818 Brahms, provisional designation 1939 PE, 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. [4] The asteroid was named after composer Johannes Brahms. [2]
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. [1] Brahms was first identified as A904 RE at the discovering observatory in 1904, extending the body's observation arc by 35 years prior to its official discovery observation. [4]
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. [3] Since asteroids in the inner main-belt are typically of stony rather than carbonaceous composition, with albedos of 0.20 or higher, Brahms'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). [3]
This minor planet is named for the German composer Johannes Brahms (1833–1897). [2] The official naming citation was published by the Minor Planet Center on 20 February 1976 ( M.P.C. 3935). [5]
