The meteorites below hail from the crusts of different planetary bodies in the inner solar system, but they have much in common. All are a rock type common in Earth's crust: basalt, a mixture of the minerals pyroxene, feldspar and olivine. Basalts are present in the rocky crusts of differentiated planets and asteroids throughout the solar system.

For example, Zagami (top) was blasted from the crust of the planet Mars by an impact about three million years ago. Camel Donga (middle) came from an asteroid, probably Vesta. The terrestrial basalt (bottom) is not a meteorite but basaltic lava from a Caribbean volcano-yet in composition and mineralogy, it is very similar to basaltic meteorites from the crusts of asteroids and other planets.
