All meteorites come from inside our solar system. Most of them are fragments of asteroids that broke apart long ago in the asteroid belt, located between Mars and Jupiter. Such fragments orbit the Sun for some time–often millions of years–before colliding with Earth.
What are meteorites composed of?
Stony meteorites are made up of minerals that contain silicates—material made of silicon and oxygen. They also contain some metal—nickel and iron. There are two major types of stony meteorites: chondrites and achondrites. Chondrites themselves are classified into two major groups: ordinary and carbonaceous.
Are meteor pieces valuable?
Meteorites are heavy, so a quality slice the size of a small dinner plate is worth thousands of dollars. A prime specimen will easily fetch $50/gram while rare examples of lunar and Martian meteorites may sell for $1,000/gram or more — almost forty times the current price of gold!
