The newest book from science writer, Elaine Scott, introduces young readers to New Horizons, the space ship that NASA built to explore Pluto and the fringes of our solar system.

Scientists decide that Pluto is no longer a planet and roams the science museum to ask the other inhabitants--such as a dinosaur, a germ, and the Earth--why scientists decide to change things.

"The reclassification of Pluto in 2006 not only decreased the number of planets in our solar system by one but also introduced the new category of dwarf planet. Readers will come to understand what separates a dwarf planet from a planet, or for that matter from any of the other bodies found within the solar system. They'll learn about Pluto itself, as well as its fellow dwarf planets, Ceres, Makemake, Haumea, and Eris"--Provided by publisher.
