Meteorites are most likely debris ejected from the sun and moon
|
|
|
Meteorites come from bodies in space that formed along with the planets and some are thought to have similar compositions to Earth’s layers
|
|
|
Meteorites come form bodies in space that formed near Earth and are thought to have the same composition as Earth.
|
|
|
Meteorites formed far outside the solar system at the same time that Earth formed

Detailed explanation-1: -The scientific interest in asteroids is due largely to their status as the remnant debris from the inner solar system formation process. Because some of these objects can collide with the Earth, asteroids are also important for having significantly modified the Earth’s biosphere in the past.
Detailed explanation-2: -When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
Detailed explanation-3: -The most important clues about the early stages of the solar system come from meteorites. Some are older than the formation of the Earth. They reveal how smaller bodies coalesced to form planets, and how our own planet developed after it had formed.
Detailed explanation-4: -NASA’s missions to study these “non-planets” help us understand how planets including Earth formed, locate hazards from incoming objects and think about the future of exploration.
