  | Full Text Reviews: School Library Journal - 10/01/2014 Gr 3–6—Revised and updated, this edition takes readers on a journey through the solar system with upgraded photos, content, and glossary from its predecessors (1992, 2007). While much of the content remains the same as the previous edition, small details have been adjusted, such as Jupiter's clouds, which are no longer "mostly hydrogen gas, not water droplets like clouds on Earth" but are now simply "frozen ammonia droplets." Although these details may be nearly imperceptible to young readers, what will stand out are the captivating photographs. The images, many of which are from NASA, are remarkably crisp and more detailed than before, giving a nod to changes in imaging technology in the past decade. As stated in the author's note, Simon uses comparisons to help readers comprehend the scale of these celestial masses ("If Earth were the size of a basketball, the sun would be as big as a basketball court."). He does not return the favor for specific calculations, though, thus leaving readers to grapple with the meaning of "the crust, which ranges from 5 to 30 miles deep" and "the mantle, an 1,800-mile-thick layer of heavy rock." Furthermore, some words do not appear in the glossary, such as typhoon and asteroid, and the unexplained transition from "800 degrees Fahrenheit" to "-300°F" may confuse some readers. However, the brief overview of the solar system and the spacecraft sent to explore it make this title a worthwhile consideration for school and public libraries.—Meaghan Darling, Plainsboro Public Library, NJ - Copyright 2014 Publishers Weekly, Library Journal and/or School Library Journal used with permission.
