Planetarium: Nine Planets and Counting September 5, 2009

'Nine Planets and Counting' is an original planetarium show created by Sudekum Planetarium at Adventure Science Center. The show not only offers an overview of the entire solar system, it addresses the timely issues the IAU is debating. The show questions the current definition of a planet, discusses the discovery of Pluto and other astronomical objects and explores all the planets in our solar system.
