This books contained information about the planet Mercury that was super basic and super easy to read. The solar system diagram, however, could have been better.
A good basic book. It seems that this publisher or book series "First Facts" keep using the same stupid solar system diagram on pages 6-7 as they do in their other planet books. How annoying. I've seen plenty of other, more realistically scaled pictures of the solar system that they could have taken ideas from.
