The International Astronomical Union has decided there are only 8 planets in the Solar System, mainly because Pluto is too small to stand out from the rest of the rubble. This National Geographic article explains neatly why Pluto does not meet solar standards to be called a full planet. It is instead considered to be a dwarf planet cousin to around 40 other dwarf planets in our solar system.
