Dwarf planet

A dwarf planet is a type of heavenly body of the solar system somewhere between a planet and a small body (comets, asteroids and trans-neptunian objects). The term was adopted in 2006 by the International Astronomical Union in order to clarify the classification of objects orbiting the sun. Today, five objects are recognised as dwarf planets: Eris, Pluto, Makemake, Haumea and Ceres.
