2009 Isaac Asimov Memorial Debate: From Planets to Plutoids

Tuesday, March 10, 2009

When the International Astronomical Union's 2006 vote reclassified Pluto as a dwarf planet, controversy followed over this most beloved object in the solar system. Recent discoveries of icy Kuiper belt objects and hot Exoplanets have forced scientists to re-think previous classification schemes and their associated nomenclature.

Join Moderator Neil deGrasse Tyson, the Frederick P. Rose Director of the Hayden Planetarium, and his panel of experts as they discuss and debate the ideas that drive our understanding of the solar system.
