Solar System Formation

are precious extra-terrestrial samples, natural objects that survive their fall to the Earth from Space. Almost all meteorites are fragments from asteroids that formed at the birth of our solar system. Isotopic dating on chondritic meteorites collected on the Earth’s surface reveal an age of our solar system of ca. 4550 Ma.
