Pluto was discovered in 1930 by Clyde W. Tombaugh. As far back as 1905, Percival Lowell felt that an unknown planet was influencing the orbits of Neptune and Uranus. However, he died without finding the planet. Tombaugh used Lowell’s work to predict the location and was successful in 1930. Pluto’s day is about six earth days, and its year is about 248 earth years. The average temperature is about -342 degrees to -369 degrees Fahrenheit. Pluto is named after the ancient god of the underworld. Pluto was demoted from planet to dwarf planet on August 24, 2006, by the International Astronomical Union. Children can learn more at: Pluto.
