'Recent' meteor impact

This is an aerial photograph of the best preserved meteorite crater on earth. This is due to the fact that this meteorite hit the earth in a dry area that we now call Arizona. It struck the earth 50,000 years ago which is very recent geologically. At the time of impact the meteorite created a crater 210 meters deep and 1200 meters across. The meteorite itself was 46 meters across. The impact would have created winds of 1,000 kms per hour and was the same a 40 Hiroshima nuclear bombs so all the plants and animals within 5 kms would have been destroyed.

Many meteorite impacts have shaped the earth and all other objects in space. It is thought that the dinosaurs were effected and eventually went extinct due to a large meteor impact 65 million years ago. Now many meteorites hit the earth every day but most of them burn up in our atmosphere, the same atmosphere were are wrecking with all our pollution.
