813 Baumeia
813 Baumeia (prov. designation: or ) 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. The common S-type asteroid has a rotation period of 10.5 hours and measures approximately in diameter. It was named for H. Baum, a German student of astronomy at Heidelberg who was killed in World War I. Orbit and classification Baumeia is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the inner main-belt at a distance of 2.2–2.3 AU once every 3 years and 4 months (1,211 days; semi-major axis of 2.22 AU). Its orbit has an eccentricity of 0.03 and an inclination of 6° with respect to the ecliptic. The body's observation arc begins with its first observation as at Heidelberg on 4 April 1907, more than 8 years prior to its official discovery observation. Naming This minor planet was named im memory of H. Baum, a German astronomy student at Heidelberg University who was in World War I. The naming was published in the
