On August 24, 2006 the International Astronomers Union, a non-governmental entity, reclassified Pluto giving it the status of Dwarf Planet. This new classification is based on their updated definition of what a planet is. One reason for the change is because the new definition requires that a planet "dominate" its orbit. Pluto's orbit crosses and is dominated by Neptune. Furthermore, scientists are discovering that the region of Pluto's orbit, which is known as the Kuiper Belt, is similar to the asteroid belt. There are many Pluto-like objects in that region, including one named Eris which is larger than Pluto. This means Pluto is more like an asteroid than it is like a planet. | On August 24, 2006 the International Astronomers Union, a non-governmental entity, reclassified Pluto giving it the status of Dwarf Planet.
