13000 Year Old Satellite. The Full Story Behind the Black Knight. This satellite was located in space in the 1960. In February 1960 US Navy had detected a dark, tumbling object in an orbit inclined at 79° from the equator with an orbital period of 104.5 minutes. Its orbit was also highly eccentric with an apogee of 1,728 km (1,074 mi) and a perigee of only 216 km (134 mi). At the time the Navy was tracking a fragment of casing from the Discoverer VIII satellite launch which had a very similar orbit.
