Dwarf Planets of Our Solar System (Infographic)  by Karl Tate  In 2006 the organization responsible for classifying celestial bodies, the International Astronomical Union, decided that a new class of objects was needed.

Some astronomers expect there may be as many as 50 dwarf planets in the solar system.
