Some meteorites are actual pieces of
the original matter from which the planets were assembled.
Others are fragments of asteroids that grew hot enough to
develop crusts, mantles, and cores. When these extraterrestrial
rocks land on Earth, they provide an extraordinary opportunity
to piece together the history of our Solar System's birth
The Old Woman meteorite, a 2753-kg mass of iron-nickel metal,
stands out against the rounded boulders in the Old Woman Mountains
of San Bernardino County, California, where it was found in
1976. Behind it is Smithsonian scientist Roy S. Clarke, Jr.
