This review is for the whole series.
I bought this and two other series of children's books on planets to help teach my students how to do research during our astronomy unit. This was the middle of the three series in terms of how much I liked it. There are no actual pictures in this series, only illustrations. And while the illustrations are done well, I don't think anything can beat real images.
As for the factual information, there's not a lot here. Basics are covered, and one or two fun facts, but no real depth.
