Meteorites from Antarctica
In 1969, the Japanese discovered concentrations of meteorites in
Antarctica. Most of these meteorites have fallen onto the ice sheet in the
last one million years |

Meteors and
meteor showers meteoroids strike the Earth's atmosphere at high
relative speeds they leave visible trails created when the intense heat
caused by friction vaporizes them. These are called meteors |

Meteorites from
New England meteoritical learn about meteorites, the term meteor comes from the Greek meteoron,
meaning phenomenon in the sky. It is used to describe the streak of light
produced as matter in the solar system falls into Earth's atmosphere
creating temporary incandescence resulting from atmospheric friction |
Meteors and
meteorites What we are witnessing when we see a shooting star is a small
piece of interplanetary matter, called a meteor, entering the Earth's
atmosphere and 'burning up' at a height of about 100 km, ... |

Asteroids (minor planets) and comets are remnant material from the process
of formation of the Solar System and the initial development of the planets |
New
England meteoritical services meteorites falling from the heavens have
mystified people for thousands of years, but it is only within the past
two hundred years that scientists have come to accept the fact that stones
do indeed fall from the sky and that they represent fragments of other
bodies in our solar system |

Terrestrial Impact
Sites impact craters are geologic structures formed when a large
meteoroid, asteroid or comet smashes into a planet or a satellite. All the
inner bodies in our solar system have been heavily bombarded by meteoroids
throughout their history |
