Question: Is the composition of meteorites different from that of ordinary rocks?

Joshua Hollowood answered on 9 Oct 2025:

Yes, meteorites are usually different from ordinary rocks you find on Earth. Many meteorites are made from minerals that formed in the early solar system and contain things you almost never see in normal Earth rocks.

Other meteorites are made mostly of metal or rock that has melted and changed inside an asteroid, so they also look different from typical Earth rocks.
