Once believed to be the ninth planet, Pluto was discovered at the Lowell Observatory in Flagstaff, AZ, by astronomer Clyde W. Tombaugh. Tombaugh discovered the tiny, dwarf planet using a new astronomic technique of photographic plates combined with a blink microscope. Pluto was given the Roman name for the god of the underworld in Greek mythology, due to its surface temperature of -218 ° C. More than six billion kilometres away from the sun, it takes Pluto approximately 248 years to complete one orbit. Pluto's only known moon, Charon, has a diameter of a mere 1186 kilometres. In 2006, it was announced that Pluto would no longer be considered a planet due to the fact that its orbit crosses into the orbit of planet Neptune. c2cbe90a755142d7b6f72a3ef66d6d0a Mon, 18 Feb 2019 16:33:45 +0000 This Day in History: Pluto Is Discovered February 18, 1930.
