This month marks the fifth anniversary of the "demotion" of Pluto from our solar system. On this week's KPR Presents, Pluto: from its 1930 discovery by Kansan Clyde Tombaugh to its 2006 declassification by the International Astronomical Union. This week's show also features humorous songs, essays, and a comedy sketch about Pluto from the Right Between the Ears archives.
