1815 Beethoven, provisional designation 1932 CE1, is a rare-type carbonaceous asteroid from the outer regions of the asteroid belt, approximately 30 kilometers in diameter. It was discovered on 27 January 1932, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany.
In the Tholen classification, Beethoven belongs to the relatively rare group of dark F-type asteroid.[1][3] A rotational lightcurve, obtained by American astronomer Robert Stephens in 2005, gave a rotation period of 54 ± 1 hours, which is a relatively slow spin rate compared to most other asteroids.[4]
This minor planet is named after German composer Ludwig van Beethoven (1770–1827).[2][5]
