Meteorites, probably the debris of celestial bodies torn apart by collision or near approach range from solid bodies of nickel-iron to rocks similar to those found on the earth. Achondrites, on the other hand, do not contain chondrules and are thought to be fragments of larger asteroids that have been broken up by collisions. Most people think that meteorites are only found in deserts or hot, arid climates. Once you decide on a location, get permission to search it from the owner or the governing body.

A meteorite, such as the Beaver L5 chondrite discovered in a jail in Oklahoma in the 1940s, has an intriguing history. In the same vein as sending a space probe to an asteroid or comet and collecting a sample but infinitely cheaper finding a meteorite whose incoming trajectory is known can reveal fresh information about the structure and composition of a distant region of the solar system.
