Meteorites 
Meteorites, the physical rocky materials left after an interstellar body
impacts with earth. Before this body flying through space actually strikes the ground it is referred to
as a meteoroid. These meteoroids finds consist of bits and pieces of
our solar system, coming from a variety of locations; asteroids, comets, and other planets being the most common of these
origins.
These meteoroids travel through space until they
are trapped by the gravitational pull of a system, or in this case Earth. They begin their decent to earth’s
surface and soon encounter the immense resistance of the friction of earth’s atmosphere. Earth’s atmosphere
may seem like it is not “solid” enough to offer up a large resisting force. In comparison to the non-existent presence of an atmosphere in the upper thermosphere and
exosphere it is a relative great leap.
It is hard for scientists to discover many
meteorites in most parts of the world, as their stony appearance conceals them in their surrounding. But
there have been thousands of meteorites discovered in the Antarctic region,
not being able to hide on the frozen layers of snow and ice. Which is vital to the research or these
space rocks.
