923 Herluga (prov. designation: A919 SK or 1919 GB) is a three-body resonant background asteroid, approximately 34 kilometers (21 miles) in diameter, located in the central region of the asteroid belt. It was discovered on 30 September 1919, by astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[1] The carbonaceous C-type asteroid has a rotation period of 19.7 hours. It was named "Herluga", a common German female name unrelated to the discoverer's contemporaries, that was taken from the almanac Lahrer Hinkender Bote.[2][3]
