This is a book aimed at children but one that is just as interesting for adults. It is, after all, about the solar system, and we can never learn too much about that.
It's a relatively quick read - probably an hour or so - but that shouldn't devalue it in any way. The information that it does contain is concise and to the point, capturing any child's imagination while laying foundations for future more detailed learning. It's up to date, too, for example Pluto is classified not as a planet, but as a 'dwarf planet, a fairly recent announcement relatively speaking. Each planet is described in brief but always useful detail, and there are mentions of meteorites, comets, asteroids, failed planets and more. There are four pages of projects for children to try, some parent-teacher notes, a glossary of various terms, and a simple quiz to see if the child has taken any notice!
If a child has yet to read anything about outer space and in particular our solar system, then this book is a great place to start. Suitable for 6 years old and up - with no limit really, because once again regardless of your age there will be something in here to make you think.
