It's smaller than any other planet -- even smaller than Earth's moon.
It's dense and rocky, like the terrestrial planets (Mercury, Venus, Earth and Mars). However, its nearest neighbors are the gaseous Jovian planets (Jupiter, Saturn, Uranus and Neptune). For this reason, many scientists believe that Pluto originated elsewhere in space and got caught in the sun's gravity. Some astronomers once theorized that Pluto used to be one of Neptune's moons.
Pluto's orbit is erratic. The planets in our solar system all orbit the sun in a relatively flat plane. Pluto, however, orbits the sun at a 17-degree angle to this plane. In addition, its orbit is exceptionally elliptical and crosses Neptune's orbit.
One of its moons, Charon, is about half Pluto's size. Some astronomers have recommended that the two objects be treated as a binary system rather than a planet and satellite.

Hey,
Your answer,
› Pluto, the ninth body after Neptune, isn't considered as a planet anymore because it is too small to be termed as a planet, even smaller than Earth's moon Luna.
› The second reason could be that it disturbs other planet's orbit with its own, which is truly not a thing that a planet must do.
>> Hope it'll work for you!
