Written by the author of Curious George, this hefty guide to stars, constellations, and planets in the night sky was first published in 1952 and revised several times, though the current book is evidently the first to be called the second edition. A star on the jacket proclaims "updated star and solar system information." Inside, additions include an introductory note on Pluto, which explains the difference between a planet and a dwarf planet, as well as a paragraph on the Kuiper Belt. Information on the solar system and the asteroid belt has been revised in the light of Pluto's reclassification. In addition, the planetary tables have been updated through 2016. The bibliography was not updated, however, and it includes no books from the last 10 years. Still, the new edition is recommended to replace old ones in astronomy collections.

Each of these new editions, which had previously been updated with information about Pluto, features a "bonus online planet locator." Both are fascinating books, full of scientific information, charts and diagrams, and lively illustrations. The "Planet Finder" charts in both are updated through 2026. Glos., ind.
