Meteorites, primordial space rocks that fall through the sky and strike the Earth's surface. Science has been able to analyse a small amount of these extraterrestrial gems forming parts of our solar system, which evolved over 4.5 billion years. Cataloguing pieces of planet and asteroids which have fallen to Earth. We can only with confidence claim to know where a handful of the estimated 50,000 - 75,000 falls to our terrestrial home, each year derive, namely the planets we have visited!
The most productive places to find meteorites are open flat regions, like the Sahara desert, where meteorites blackened on the outside by their fiery passage through the atmosphere stick out among the light coloured sand. With thousands of miles of ground to cover, finding them is a huge task.
