From the reviews: "This delightful book ... is really a breath of fresh air in popular science publishing, taking us back to astronomical basics and starting from the beginning. With the help of very clear diagrams and graphics, the text takes you through fully-worked examples, asking questions about sizes, distances and motions within the Solar System. It then sets about, always with simple, readily available and inexpensive equipment, to show you how to answer those questions for yourself. ... Overall, this is a very worthwhile text ... ."
