Why is Pluto no longer a planet?

What happened??

Jessie B.

Hi Thomas,


Drew answered your question thoroughly and I will elaborate a little on it.  Pluto was no longer considered a planet in 2006.  One easy way to picture why this is the case is because Pluto is smaller than our Moon!  To our understanding, Pluto is just a chunk of rock that is smaller than our Moon and rotates around the Sun differently from the eight planets.  In order to be considered a planet, it must rotate around the Sun in a circle and have significant size.

Planets rotate on their axes and revolve around the sun in elliptical (not circular) See orbhttp://news.nationalgeographic.com/news/2006/08/060824-pluto-planet_2.htmlits.  for reasons why Pluto is no longer considered a full-fledged planet.
 
Percival Lowell (PL) and (u) Clyde Tombaugh (TO) would not be happy to hear the news about Pluto.
