Most people are familiar with the term "shooting star". Actually, it is not a star shooting across the sky, but a small piece of solid matter called a meteoroid colliding with the atmosphere.


As the meteoroid enters the Earth's atmosphere, the friction created by its incoming velocity causes its surface to heat up, and the brilliant flash of light records the passage of a meteor. Should the object survive this firey plunge through the atmosphere and hit the ground, it then becomes a meteorite.


Most meteorites are fragments of asteroids that broke apart long ago in the asteroid belt, located between Mars and Jupiter. Such fragments orbit the Sun for some time - millions of years - before colliding with Earth. Very few meteorites come from Mars and our Moon, some might even come from a Comet.



(German version)
Die meisten Leute kennen das Wort «Sternschnuppe». Diese Objekte sind aber keinesfalls Sterne, sondern kleine Stücke, Meteoriden genannt und sie kollidieren mit der Erdatmosphäre.

Durch die hohe Geschwindigkeit und die Reibung in der Atmosphäre beginnen sie zu glühen und sie können - obwohl meist sehr klein - weithin gesehen werden. Falls Teile davon die Reise durch die Atmosphäre überstehen und die Erde erreichen, nennt man sie Meteorite.

Die meisten Meteorite sind Fragmente, die vor langer Zeit im Asteriodengürtel - zwischen Mars und Jupiter - auseinander gebrochen sind. Die Fragmente umkreisen die Sonne während Millionen von Jahren bis sie eines Tages auf unsere Erde stürzen. Einige wenige Meteoriten stammen von Mars und Erdmond.

50000 years ago an iron meteorite - about 30 m in diameter - struck the Earth. The resulting explosion created a crater 1500 m in diameter and 180 m deep.
This crater is called «Barringer Meteorite Crater» or «Meteor Crater».
Meteorites that survived the impact had been found around the crater and are called «Canyon Diablo» meteorites.
