Meteorites are the remnants of meteors from outer space that have survived the corridor of fire through Earth's atmosphere and landed on our planet. Rare, and bearing secrets about the formation of our Universe, these 'treasures from space' have fascinated people ever since they were first identified in the late 18th century as extraterrestrial arrivals. This jam-packed book by enthusiast and collector Ronnie McKenzie introduces the topic in straightforward language and is richly illustrated with some 200 photographs and diagrams. It discusses how to identify meteorites, where they come from and where they have landed on Earth, the many different types, and how to set about collecting them. It also dispels some of the myths about these stones, and presents some infamous meteorite scams. A handy basic guide for those new to the topic, and for anyone interested in entering the field of meteorite collecting.
