The Pluto Files

November 3, 2008
From Pluto's 1930 discovery to the emotional reaction worldwide to its demotion from planetary status, astrophysicist, science popularizer and Hayden Planetarium director deGrasse Tyson (Death by Black Hole
) offers a lighthearted look at the planet. Astronomical calculations predicted the presence of a “mysterious and distant Planet X” decades before Clyde Tombaugh spotted it in 1930. DeGrasse Tyson speculates on why straw polls show Pluto to be the favorite planet of American elementary school students (for one, “Pluto sounds the most like a punch line to a hilarious joke”). But Pluto's rock and ice composition, backward rotation and problematic orbit raised suspicions. As the question of Pluto's nature was being debated by scientists, the newly constructed Rose Center for Earth and Space at the Hayden Planetarium quietly but definitively relegated Pluto to the icy realm of Kuiper Belt Objects (cold, distant leftovers from the solar system's formation), raising a firestorm. Astronomers discussed and argued and finally created an official definition of what makes a planet. This account, if a bit Tyson-centric, presents the medicine of hard science with a sugarcoating of lightness and humor. 35 color and 10 b&w illus.

When astronomers stripped Pluto of its "planethood" in 2006, it set off a surprisingly passionate debate. As director of the Hayden Planetarium in New York City, Neil deGrasse Tyson was at the center of the dispute, and he tells his side of the story with wit and humility in this audio. Mirron Willis doesn't sound entirely comfortable with the scientific language (despite a number of credits as an actor and narrator in sci-fi), but he does a fine job conveying the audiobook's humor, including the letters from children who are angry that Tyson helped to demote their favorite planet. It's unclear why the publisher elected to include the glossary and the other appendices that don't work well in audio, except perhaps to pad out a very brief recording. D.B.

Many blame astrophysicist and Hayden Planetarium director Tyson ("Death by Black Hole") for the International Astronomy Union's demotion of Pluto to a dwarf planet in 2006. Here, he tells his tale while exploring the history of planet classification and Americans' fervid interest in Pluto's status. At first, actor/narrator Mirron Willis's ("Basketball Jones") reading is a bit slow, but he relaxes more as the story progresses to a discussion of our love affair with Pluto; he successfully gets Tyson's often tongue-and-cheek tone across to the listener. An enjoyable title on a topic having broad appeal.
