Pluto’s Secret, an Icy World’s Tale of Discovery by Margaret A. Weitekamp with David DeVorkin lets the cat out of the bag. Dancing around with its moon and other small worlds on the outer edges of the solar system, it watches as the people on Earth try to figure it out. Discovered in 1930 after years of searching, astronomers thought they had found the ninth planet around the sun. Pluto plays in its orbit, laughing at the astronomers. As more powerful telescopes are developed, scientists realize that Pluto is not only different than the other planets; it’s also not alone in its orbit. In 2006, this discovery led astronomers to vote on a definition of a planet, something which had never been done before. Pluto’s secret is revealed. It is not a planet, but the "first example of something new" --and it’s not the only one. Scientists have discovered an entire band of icy worlds around the sun (called the Kuiper Belt), as well as around other stars. As technology evolves, so does our ability to learn more about the Universe.
This children’s book, put out in association with the Smithsonian National Air and Space Museum, does an extraordinary job of piquing the reader’s interest in the solar system. Children will enjoy learning that an 11-year-old girl suggested the name for Pluto. Coupled with Diane Kidd’s charming illustrations, the story will entertain readers of all ages. Facts and photographs follow the story and gives those interested more resources. In 2006 NASA launched the New Horizons spacecraft to conduct a flyby study of Pluto and its moon, Charon. It’s halfway there, and should reach Pluto in 2015. Follow its progress here!
