Comments for Space
Space by Carole Stott was originally published in the "Worldwise" series in the 1990s and is now part of DK Publishing's "Eye Wonder" series.
Space is a solid introduction to astronomy. The book covers things like rotation (a planet's day) and revolution (a planet's year), the different kinds of stars, differences of scale of the planets and so forth. Each new subject is expanded upon across a two page spread.
The book is designed for ages 4 to 8 and it is interesting enough to read in one sitting but is solid enough to be used as a reference book for looking up facts.
The cover I'm displaying is from the old "Worldwise" series but if you follow the link it will take you to the more recent "Eye Wonder" series.
