\"meteor-crater1\"Kamil crater, at only about 150 feet wide and 50 feet deep, may not break any size records–but what the Egyptian crater lacks in range it makes up for with cleanliness. In an paper<\/a> published yesterday in Science<\/em>, researchers say that its “pristine” impact, spotted in 2009 during a Google Earth<\/a> survey, makes the crater an ideal model to understand similar impacts.<\/p>

The best place to see a clean crater? Rocky or icy planets without an atmosphere. Earth’s weather quickly erodes a crater’s structures, making it difficult to determine how exactly a meteorite struck. The Kamil crater, study leader Luigi Folco says, has avoided this fate:<\/p>

“This crater is really a kind of beauty because it’s so well-preserved that it will tell us a lot about small-scale meteorite impacts on the Earth’s crust…. It’s so nice. It’s so neat. There is something extraordinary about it.” [Space.com<\/a>]<\/p><\/blockquote>

<\/span>\"meteor-crater2\"The crater rises above its desert surroundings, <\/em>and during visits to the site over the past two years researchers have collected around 5,000 iron meteorites (the dark rocks pictured at right). They estimate that the original meteorite weighed between 5 and 10 tons and smacked the site at 7,800 miles per hour, giving the crater its characteristics, including “rays” that are visible in satellite photos<\/a>.<\/p>

These rays, which emanate from the impact site like spokes from the hub of a wheel, are what drew researchers’ attention to the crater, says Folco. While such “rayed craters” are common on the moon and other airless bodies of the solar system, they are exceedingly rare on Earth because erosion and other geological processes quickly erase such evidence.

Researchers estimate that the site is relatively young, only about 5,000 years old, given that it must have struck at a time when Egypt’s deserts were in their current arid state.<\/p>
