THE PLUTO DEBATE

The Pluto Debate: The International Astronomical Union Defines a Planet Microgame

by Anthony Crider

Science isn't Usually Done by a Vote
In this game, students play one of nine astronomers arguing the definition of a planet at a 1999 debate in New York City and a 2006 meeting of the International Astronomical Union. During this game, students will do the following:

  • Compare the history of Pluto’s discovery to that of the asteroid Ceres
  • Describe the properties of the Kuiper Belt and its members
  • Plot the orbital and physical properties of planets, asteroids, and comets
  • Debate the necessity and value of scientific classifications
