Once the proud out ermost planet of the Solar System, Pluto has been consigned to the status of a small-town telephone number after the world's paramount astronomical body tore up its membership of the cosmic A-list. The enigmatic, icy world spotted in 1930 has been given the official moniker of 134340 Pluto and lumped among 136,562 asteroid and other small bodies by the Minor Planet Centre (MPC), part of the Paris-headquartered International Astronomical Union.
