Have you ever wondered why Pluto is not a planet anymore? After years of astronomers and scientists discovering something about Pluto, they decided to kick it off the solar system. My Astronomy professor has one of the reasons why...meaning the one I am writing is the main reason.
In the words of Dr. Russel J. Lavery, IVC Astronomer.
Pluto is not a Planet anymore because scientists and astronomers 15 years ago have discovered Ice Pellets that look similar to Pluto. Those ice pellets do orbit with Pluto, but if those pellets join Pluto, then we won't tell if the planet is orbiting or not. It does seem that they are orbiting Neptune. Some Pellets are the size of Pluto, however, it is not considered a planet at all.
