Meteorites from asteroids and even from other planets help scientists understand all planets in our solar system, particularly the processes taking place deep inside. Although no one has ever been to the center of Earth, we know from meteorites that Earth has a center, or core, made of nickel and iron metal.
Some meteorites contain grains of dust (“stardust”) that were produced by stars before the formation of our Solar System. Studies of these presolar grains can increase our understanding of star formation and evolution
