Clyde Tombaugh discovered Pluto on 18 February, 1930. Pluto is named after the Greek god of the underworld, a name it got after the naming of the planet was opened up as a competition. Tombaugh discovered Pluto during a systematic search for a new planet, imaginatively called 'Planet X', which Percival Lowell thought was causing Neptune to stray off course. Tombaugh took slides of the region the new planet was thought to be in, in pairs. He then had the painstaking task of comparing the pairs of slides to see if anything had moved against the background of stars.
