Nitpick: Dwarf planets are not a type of planet, but in fact a wholly separate category.

From Wikipedia: "In 2006 the concept was adopted by the International Astronomical Union (IAU) as a category of sub-planetary objects, part of a three-way recategorization of bodies orbiting the Sun: planets, dwarf planets and small Solar System bodies. […] Since 2006 the IAU and perhaps the majority of astronomers have excluded them from the roster of planets."
