You would not want to go to school on Pluto because one day on Pluto would be six days on Earth! Pluto is smaller than our moon, barely over 1,300 miles in diameter. It has a tiny moon named Charon which wasn't discovered until 1978. Pluto was discovered by Clyde Tombaugh in 1930. The average temperature on Pluto is -390 degrees F (-234 degrees C). The atmosphere is made up mostly of nitrogen and methane.
Pluto has not been visited by spacecraft once since we realized it was there! But, in 2016, if all goes well, a spacecraft will land on Pluto. It will take the space craft 10 years to reach Pluto. It has a big dish antenna on top, and miniature cameras.
