A meteor crater found in Egypt

Kamil crater was originally discovered in February during a survey of satellite imagery in Google Earth. Researchers assess the crater was formed in the last few thousand years.

Italian-Egyptian team that discovered the crater was found with a hole 45 meters to 16 meters dalamanan. The team also collected thousands of pieces of space rock that littered the surrounding desert.

Based on their calculations, the team assessing an iron meteorite with a width of 1.3 meters with a weight of 5 to 10 tons. Velocity is estimated to exceed 3.5 kilometers per second.

No data how many meteors this size that has been hit the earth. But scientists think that the threat could potentially reach tens of thousands.

The model will be shown an iron meteor about the size it is usually broken in small pieces before on earth.

Conversely, the existence of a new crater had shown that 35% of this giant iron can actually survive as a whole, and thus have a greater destructive force.

Estimating the fall of the meteor harmful to the earth is not an exact science, because only 176 craters have been discovered so far, according to database resources managed by the University of New Brunswick in Canada.

Most models based on the number of craters on the moon, which is almost no atmosphere and did not experience erosion processes such as the earth.

"The model predicts that about a thousand to ten thousand craters should have been formed [the earth] in a million years," said study co-author Luigi Folco, a scientist at the University of Siena in Italy.

"The reasons why are rarely seen because the earth experienced a high degree of weathering, craters are usually easily eroded or buried
