The planets in our solar system are a constant source of wonder for young readers. In an update of her first popular edition, Gibbons depicts each planet in a full-colour spread and explores the latest scientific findings and information. Gibbons discusses what a planet is, a history of the planets' discoveries, an astronomer's role in space exploration, and how to use a telescope. Once again Gibbons provides a colourful, accessible, and now updated account of these heavenly bodies.
