問題詳情

(三)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 even smaller than the moon. So, at a meeting in 2006, the astronomers decided to take Pluto off the list of planets in our solar system.　　Now, there are 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?phpOCF1fQ
