2181 Fogelin (prov. designation: 1942 YA) is an Eunomia asteroid from the central regions of the asteroid belt, approximately 11 kilometers (7 miles) in diameter. It was discovered on 28 December 1942, by Germany astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[1] In 1980, it was named for Eric S. Fogelin an assistant at the Minor Planet Center.[1] The likely elongated S-type asteroid has a rotation period of 14.07 hours.[3]
