Meteroite

Once thought to be a sign of impending doom, most meteorites are debris left by a comet or asteroid that is orbiting the sun, but some come from the Moon or Mars.

One of the two daggers buried with King Tutankhamen was made out of meteorite.

In 1961, the International Astronomical Union defined a meteoroid as "a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom".

Most of these extra terrestrial objects burn up in Earth's atmosphere. Only the 500 that reach the ground annually are known as meteorites.

The Ensisheim Meteorite, the oldest meteorite with a known date of impact, struck the earth around noon in a wheat field outside the village of Ensisheim, Alsace, France on November 7, 1492. The fall of the meteorite through the Earth's atmosphere was observed as a fireball for a distance of up to 93 miles (150 kms) from where it eventually landed. The meteorite can still be seen in Ensisheim's museum, the sixteenth-century Musée de la Régence.

The Hodges Meteorite crashed through a roof of a home in Sylacauga, Alabama, United States on November 30, 1954. It hit Ann Hodges who was taking an afternoon nap, striking her on the thigh, leaving a huge pineapple-shaped bruise. The event was the only documented case of a human being hit by a rock from space.



The largest individual meteorite ever found is the Hoba meteorite in southwest Africa, which has a mass of about 54,000 kg and mostly consists of iron.

The town of Nordlingen in Germany was built unknowingly in a meteorite crater. It's stone buildings contain thousands of tons of micro-diamonds.

Earth is hit by six tons of meteorites every day.


Peridots are the only gems that have been found in meteorites.
