In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of "dwarf planet." This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.

Answer:

Pluto was not considered a planet because of how small it was, therefore Pluto was removed from the solar system.
