813 Baumeia (prov. designation: A915 WJ or 1915 YR) is a stony background asteroid from the inner regions of the asteroid belt. It was discovered on 28 November 1915, by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany.^[1] The common S-type asteroid has a rotation period of 10.5 hours and measures approximately 12 kilometers (7.5 miles) in diameter. It was named for H. Baum, a German student of astronomy at Heidelberg who was killed in World War I.^[2]
