    The total number of new-style designations assigned by the Minor Planet Center (and its predecessors) is 1111087. The following table lists the number of new-style minor-planet provisional designations assigned in each year, as well as the number of omitted and deleted designations and the number of designations identified with numbered minor planets, comets and natural satellites. Also given are the number of designations involved in unnumbered identifications (Unn.) and the number of designations that are principal designations (Prin.). Beyond these columns is a half-monthly breakdown of the yearly total of assigned designations. The data are complete through the latest batch of Minor Planet Circulars.
