1106 Cydonia (/saɪˈdoʊniə/), provisional designation 1929 CW, is a Eunomian asteroid from the central regions of the asteroid belt, approximately 13 kilometers (8 miles) in diameter. It was discovered on 5 February 1929, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany.[12] The asteroid was named for the fruit-bearing tree Cydonia (quince).[3] The S-type asteroid has a relatively short rotation period of 2.7 hours.[4]
