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.
