The International Astronomical Union has downgraded Pluto!! On Thursday, Aug. 24, the 2006 General Assembly passed six resolutions including one that defines planets and another that defines Pluto as a "dwarf planet", leaving only eight planets in our solar system.
NASA's Solar System Exploration website has been edited to show this change on its Pluto page.
