1119 Euboea (/juːˈbiːə/; prov. designation: 1927 UB) is a background asteroid from the central region of the asteroid belt. It was discovered on 27 October 1927, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[3] The asteroid has a rotation period of 11.4 hours and measures approximately 30 kilometers (19 miles) in diameter. It was named for the Greek island of Euboea.[2]
