Its still a planet to me, and always will be.
Are you refferring to Pluto?
Pluto’s diameter is 2,377 km... By comparison our moon's diameter is about 3,474 km. Yes, our moon is larger than little Pluto. Hard to call it much of a planet when you think about that.
If you call Pluto a planet then there are 1000's of other bodies in orbit around our sun that would also qualify as planets. When Pluto was discovered they could barely detect it with the telescopes of the day. Now with modern ones they have found many more out there that, like Pluto are really too small to be a real planet.
