A majority of these meteorites comes from collisions in the asteroid belt between Mars and Jupiter.
To solve the problem, we need to study a lot more comets and meteorites.
A meteor that reaches the Earth's surface because it has not been burned up by friction with the atmosphere. Meteorites are believed to be fragments of comets and asteroids. ◇ Meteorites that consist mostly of silicates are called stony meteorites and are classified as either chondrites or achondrites. ◇ Meteorites that consist mostly of iron are called iron meteorites. ◇ Meteorites that consist of a mixture of silicates and iron are called stony-iron meteorites.
Note: Meteorites are bodies that are left over from the time when the planets formed, and therefore give us clues about the formation of the solar system.
