Did you know that some asteroids have volcanic rocks on their surfaces? Or that others are covered by sedimentary rocks? Or metamorphic rocks? Or that some asteroids have melted and separated into rocky outer layers over an iron core like the Earth? The same processes that made the earth’s crust and rocks also made the rocks and crusts of the asteroids – and the pieces of asteroids we have on earth: the meteorites. Follow the links below to explore the links between asteroids, meteorites and the rocks in your back yard, and take your own pictures of some asteroids!
