The Earth hitting after 35% meteorites enter atmosphere does not break


A small impact crater discovered in the Egyptian desert could change the calculations of risk of impact on our planet, according to a recent study. The Kamil crater, one of the best preserved of those found on the Earth, was discovered in February during a survey of satellite images with Google Earth. It is believed that the crater was formed in the last two thousand years. 
The Italian and Egyptian crater found recently visited and studied the hole 45 meters wide by 16 deep. They also collected thousands of pieces of space rocks scattered in the surrounding desert. Based on the calculations, the team believes that a solid iron meteorite, almost intact, between 5,000 and 10,000 kilos crashed into the desert at speeds in excess of 3.5 kilometers per second.

An asteroid impact with Earth of Consequences


Geological studies conducted over the last decades have shown us that our planet has undergone a similar meteoric bombardment suffered by the Moon, and even more intense. In fact, due to its greater gravity, the impact rate on Earth is 1.5 times higher than our natural satellite. 


The size range of objects striking bodies is between a few meters to others of several kilometers across, and producing very different effects of different factors: the diameter of the shock, their speed, their density, the place to occur impact either on sea or land, etc.. An example of this was the "Tunguska Event" which little impact (June 30, 1908) has gone unnoticed, because it took place on a spot on the planet virtually underpopulated. What would have happened if the case occurred on an urban or densely populated area?
