910 Anneliese (prov. designation: A919 EC or 1919 FB) is a dark background asteroid, approximately 48 kilometers (30 miles) in diameter, located in the outer regions of the asteroid belt. It was discovered on 1 March 1919, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The carbonaceous C-type asteroid (Ch) has a rotation period of 11.3 hours and is likely spherical in shape. It was named by German astronomer Julius Dick after his friend "Anneliese".[3]
Anneliese is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.[5][6] It orbits the Sun in the outer asteroid belt at a distance of 2.5–3.4 AU once every 5.00 years (1,828 days; semi-major axis of 2.93 AU). Its orbit has an eccentricity of 0.15 and an inclination of 9° with respect to the ecliptic.[4] The body's observation arc begins at Heidelberg Observatory on 19 March 1919, or 18 days after its official discovery observation.[1]
Naming
This minor planet was named after "Anneliese", an acquaintance of the German astronomer Julius Dick from the Babelsberg Observatory, who suggested the asteroid's name. The naming was also mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 88).[3]
