Asteroid Strikes Sudan
Last year scientists spotted an asteroid falling to earth. The asteroid was only spotted a day before it struck the Sudanese desert, so the asteroid was not found until now. When the asteroid entered earth's atmosphere it was about 80 tons and the size of a car. The asteroid was broken down by earth's atmosphere and disintegrated about 23 miles over the Sudanese desert. The asteroid's collision with earth released about 1 to 2 kilotons of TNT. Scientists combing the desert in Sudan have found over 280 pieces of asteroid, weighing 10 pounds in total. The asteroid found was of a rare breed known as Ureilites, which are break offs from larger asteroids. The larger mass that the asteroid striking earth was once a member of actually was large enough to have geological processes. This asteroid is significant because scientists can analyze the elements and makeup of it to better understand where asteroids come from; containing some of the most primitive materials left over from our solar system's creation./
