In 1930 Clyde Tombaugh was acclaimed the discoverer of a 9th planet in the solar system, Pluto. In 2006, a meeting of the International Astronomical Union removed Pluto's status as a major planet - an action that displeased many, especially in the United States. This talk will explore the issues behind the Pluto controversy and investigate the properties of other solar system objects that are as bit or almost as big as the once 9th planet.
