(164121) 2003 YT1, provisional designation 2003 YT1, is a bright asteroid and synchronous binary system on a highly eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 2 kilometers (1.2 miles) in diameter. It was discovered on 18 December 2003, by astronomers with the Catalina Sky Survey at the Catalina Station near Tucson, Arizona, in the United States.[1] The V-type asteroid has a short rotation period of 2.3 hours.[12] Its 210-meter sized minor-planet moon was discovered at Arecibo Observatory in May 2004.[3][4]
