Did you know that Mercury has a crater 810 miles (1,300 kilometers) wide? Or that that the planets ridges and cliffs formed when its core cooled and shrank millions of years ago? Look inside to learn more about Mercury and its place in the solar system.
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.
