Why did the scientists cancel 'the Pluto' among the nine planets?

Answer 1

it was too small

Answer 2

Something about how in order to be considered a planet, the celestial body has to orbit the Sun in a circular path ( well it is more like an ellipse), called a revolution. Pluto doesn't. I think I read somewhere that Pluto could have been one of Saturn's moons. But every someodd years Pluto and Neptune switch places somehow (I am not too clear about this part). So now as we know it, Pluto is not considered a planet


P.S. Zac has got the answer you seek ^_^

Answer 3

Pluto's planetary status has been tenuous ever since its discovery in 1930, due to its small size, icy composition and odd orbit. To be called a planet, a celestial body must be in orbit around a star while not itself being a star.

It must be large enough in mass for its own gravity to pull it into a nearly spherical shape and have cleared the neighbourhood around its orbit.
Pluto was disqualified because its oblong orbit overlaps with Neptune's. It will now be be known as a dwarf planet.
