(31-33) Pluto was found in 1930. It used to be the ninth planet in the solar system until the IAU（國際天文聯盟）changed it on August 24, 2006.Many astronomers argued about whether to call Pluto a planet or not. Some thought that it was too small to be called a planet—it is evensmaller than the moon. So, at a meeting in 2006, the astronomers decided to take Pluto off the list of planets in our solar system. Pluto is nolonger a planet in our solar system. It was plutoed. Pluto is farther from the sun than the eight planets. If you stood on Pluto, the sun would look just like a bright star in the sky. Plutois so far away from the sun that it gets little of the sun’s heat and takes 247 Earth years just to orbit the sun once.Now, there are only eight planets in the solar system. But if you are a fan of Pluto, don't worry. Astronomers sometimes change the rules.Perhaps they will change their mind at the next meeting. Who knows?
