Why pluto is a dwarf planet

According to the lattest definition of a planet by the International Astronomical Union (IAU), a planet is a body in near circular orbit around a star which is big enough for the force of gravity to make it round and should not take more than 200 years to revolve around the sun. Pluto takes 248 years to revolve around the sun and so it is disqualified to be a planet. Also it is too small to be called as a planet.
A dwarf planet orbits the sun just like other planets, but it is smaller. A dwarf planet is so small it cannot clear other objects out of its path. So Pluto and objects like it are now called dwarf planets.
