This is a straightforward introduction to the planets and the solar system. In the introductory description of life on Earth, readers may be confused by the poorly aligned text and photos; a clearer but simplistic description of the sun and the planets and their moons follows, with large color photographs, illustrations, and captions. A "Build an Alien" drawing activity is included. (c) Copyright 2017. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
