Containing star charts, a guide to the constellations, and details about seasons and the movement of the objects we see in the sky, this classic book makes H. A. Rey’s passion for astronomy evident on every page.
Second edition updates concentrate on the planetary and solar system information in the latter part of the book. Facts and figures for each planet have been revised, and new scientific information has been added, such as Pluto’s reclassification as a dwarf planet

From School Library Journal
Grade 4–6—This much-needed update of Rey's classic work (Houghton, 1976) features a cleaner typeface but retains the layout and most of the graphics of the previous edition. Some images, such as the picture of a spaceship, are dated but maintain, along with the small elves who guide readers through the book, all of the original charm. The primary update, featured on the cover, involves the change in Pluto's status; a great touch is the inclusion of definitions for "planet" and "dwarf planet" to help readers understand exactly why there are now only eight planets in our solar system. Statistical data, particularly for sizes and distances between the Sun and the planets, are updated; the planet finder now covers the years 2007 through 2016; and there is a new list of books for further reading. With its enduring appeal, current information, and exceptional sky charts to help find constellations, stars, and planets, this revision should be an essential purchase for all libraries.—Jeffrey A.
