Q: When is a planet not a planet?
Scientists have argued for years over the answer to this question. And central to their debate has been Pluto, the tiny orb circling the Sun at the outermost reaches of our solar system. Then on August 24, 2006, a group of astronomers made a big announcement: Pluto could no longer be considered a planet.
    
This fascinating and breathtaking audiobook explains in simple terms how advancements in technology have changed our understanding of the universe–and exactly how and why the number of planets in our solar system went from nine to eight.

      Elaine Scott's book does more than explain the demotion of Pluto to dwarf planet--it places the evolution of our understanding of the solar system on a historical time line. Pete Larkin's narration is accessible to young listeners. His pace is comfortable--not so fast that youngsters will get lost nor so slow that they'll disengage. The weakness of the production is the sci-fi-sounding musical interludes that introduce "Space Facts"--mini-biographies of scientific pioneers such as Ptolmey and Kepler. These occur often enough to significantly disrupt the flow of the material. The glossary explains the language of astronomers in terms that 7-12-year-old students can understand. N.E.M.
