Why is Pluto not considerred a planet anymore?

Answer 1

In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet. It was downgraded because it did not meet the three criteria the IAU uses to define a full-sized planet. Pluto meets all the criteria except one: it hasnâ??t cleared its neighboring region of other objects.

Pluto is not considered a planet anymore because in 2006 the International Astronomical Union redefined the criteria for what constitutes a planet.
