Is Pluto a Planet?

I think Pluto is a planet because when you look in a astronomy map of all the planets and stars you see all the planets including Pluto. Another reason why i think Pluto is a planet is because it was once a moon of Neptune and had drifted apart and was classified as an official planet in 1999. Also when you watch tv shows such as Sailor Moon, they show all the planets including Pluto.
