1111 Reinmuthia (prov. designation: 1927 CO) is a very elongated asteroid from the background population, located in the outer region of the asteroid belt. It was discovered on 11 February 1927, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[3] The F-type asteroid (FX) has a short rotation period of 4.02 hours and measures approximately 40 kilometers (25 miles) in diameter.[7] It was later named in honor of Karl Reinmuth, the discoverer himself.[2]
