Earth: Our Planet in Space, by Seymour Simon

Excellent arial photographs of the planets and our earth's geography. This non-fictional picture book puts the planets and our earth's surfaces into proper perspective in relation to each other. It also gives readers straightforward and interesting explanations of the facts governing what we see in the photos. It's a good launchpad for further scientific reading. Great to read to a younger audience (ages 5-8), too.
