Lunar meteorites are achondrites that crashed to Earth from the Moon, while Martian achondrites crashed to Earth from our neighbor planet, Mars. Astronomers think carbonaceous chondrites formed far away from the sun as the early solar system developed. They differ in their amount of iron-nickel metal and what they reveal about the early solar system. Meteorites are all shapes and sizes and come in many colors. Meteoroids are what we call space rocks that range in size from dust grains to small asteroids. The groups indicate the meteorites quantity of iron. The extinction of most life on Earth 65 million years ago is a good example of that.

Dont expect to find meteorites after a meteor shower. Streak Test: Scratch your specimen on a ceramic tile. Most achondrites form from the brittle outer layers of asteroids, which are similar to Earths crust. But how do we know? Meteorites. The primitive achondrite group, for instance, has a very similar mineral composition to chondrites. There are three basic types of meteorites, the irons, stony, and the stony-irons. Similarly, the weathering of Earth rocks can make some resemble meteorites. Some meteoroids are rocky, while others are metallic, or combinations of rock and metal.
