    Pluto was discovered by the astronomer Clyde W. Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 when he was comparing photographic plates taken on January 23rd and 29th. After the observatory obtained confirming photographs, the news of the discovery was telegraphed to the Harvard College Observatory on March 13, 1930. The planet was later found on photographs dating back to March 19, 1915. Tombaugh was searching for a "Planet X" to explain discrepancies in the predicted orbit of Neptune.
