In 2006 the International Astronomical Union redefined planets and thereby disqualified Pluto under one of the criteria. A planet has to evidence hydrostatic equilibrium - basically, be large enough or have enough gravity to form into a spheroidal shape; it has to be in orbit around the Sun (and not for example, another planet), and it has to have cleared a significant fraction of its orbit - which Pluto has not. Hence it was demoted to a minor or dwarf planet (specifically, a Plutino).
