Notes

39 pages : illustrations (chiefly colour). Published in association with the Smithsonian National Air and Space Museum Summary: People have been baffled, bewildered, and even outraged by the fact that Pluto is no longer called a planet. Through artwork and an entertaining dialogue format, this book explains why this is so. Providing a history of the small, icy world from its discovery and naming to its recent reclassification, this book presents a look at how scientists organise and class our solar system as they gain new insights into how it works and what types of things exist within it.
