Satellite Catalog Number
From Wikipedia, the free encyclopedia
The Satellite Catalog Number (also known as NORAD Catalog Number, NASA catalog number, USSPACECOM object number or simply Catalog number and similar variants) is a sequential 5-digit number assigned by USSPACECOM to all Earth orbiting satellites in order of identification. Before USSPACECOM, the catalog was maintained by NORAD. The first catalogued object, catalog number 00001, is the Sputnik 1 launch vehicle.
A search of the NSSDC Master Catalog at the end of October 2010 listed 6,578 satellites launched into orbit since 1957, the latest being Chang'e 2, on 1 October 2010.[1]
