It 'was caused by a small meteorite and' able to penetrate the Earth's atmosphere
They called and Kamil crater was caused by a meteorite that despite its small size it is able to penetrate the Earth's atmosphere, creating a crater nearly the whole measuring 45 meters in diameter.
To describe in Science this crater discovered in southern Egypt is an Egyptian-Italian research team coordinated by Italy with Luigi Folco of the National Museum, University of Siena. Contrary to what some models, Fulk said, this crater "shows us that even small metallic meteorites, in this case with a diameter of 1.3 meters, can enter the Earth's atmosphere without breaking" and this, according to the study, represents a danger previously underestimated.
Identified thanks to Google Earth images, the crater, says the expert, is characterized by the distribution of debris in the form of rays, which makes it unique because how these structures are clearly visible only on planetary bodies in the solar system devoid of atmosphere, on Earth, but these structures have been eroded by weather. The radial distribution of the debris remained intact due to young age of the crater which scientists would be formed after the Egyptian Sahara iperaridità came into being about 5000 years ago.
"The extraordinary conservation of the crater - said Fulk - allows us to study the effects of a meteorite impact due to the nature and size of this risk and to assess the impact of these celestial bodies." Unlike non-metallic meteorites that tend to explode in midair, it would seem, he adds, that the metallic meteorites does not frantumino in 35% of cases, falling on the Earth whole.
