HISTORY OF PLUTO
• It was first discovered as the ninth planet on February 18th, 1930 by astronomer, Tombaugh
• The discovery of Pluto was publicly announced on March 13th, 1930
• The surface temperature of Pluto is an estimated approximate of -360 Fahrenheit
• Pluto is named after the Roman name for the god of the underworld (in Greek mythology, this god’s name is Hades)
• The average distance from Pluto to the Sun is almost 4 billion miles
• It takes approximately 248 Earth years for Pluto to complete a single orbit
• Pluto has the most elliptical and tilted orbit of any of the planets
• When at its closest point to the Sun, it passes inside the orbit of Neptune (the eighth planet)
PLUTO AND CHARON
• James Christy and Robert Harrington discovered Pluto’s only known moon, Charon, in 1978
• Charon was determined to have a diameter of 737 miles to Pluto's 1,428 miles
• It as thought that, together, Charon and Pluto formed a double-planet system – which was ample enough mass to cause wobbles in Uranus’ and Neptune’s orbits
In August 2006, the International Astronomical Union announced that Pluto would no longer be considered a planet, due to new rules that said planets must "clear the neighborhood around its orbit." Since Pluto's oblong orbit overlaps that of Neptune, it was disqualified.

INTERESTING FACTS
• Pluto is named after the Roman god of the underworld (in Greek: Hades)
• No spacecraft has visited Pluto
• Though in July 2015 the spacecraft New Horizons, which was launched in 2006, is scheduled to fly by Pluto on it’s way to the Kuiper Belt.
• Pluto takes the longest time of the eight planets (248 Earth years) to orbit around the sun.
• Pluto spins in the opposite direction as Earth, which means the sun rises in the west and sets in the east.
• It takes about five hours for sunlight to reach Pluto
• In astrology, Pluto is associated with powers of creation/rebirth as well as destruction/death
• The sky is so dark on Pluto that a person would be able to see stars during the day
