On 14 April, 2010 a huge fireboall was seen over at least seven midwestern US states including Wisconsin, Michigan, Iowa, Minnesota and Illinois etc... Data collected by scientists at NASA's Marshall's Space Flight Center, Huntsville, Ala., indicate the parent body of the fireball was approx 1 meter (3.3 feet) in length and was not associated with the Gamma Virginids meteor shower, which was taking place at the time the fireball entered the atmosphere. Instead, the small space rock more than likely originated from somewhere in the asteroid belt.When the fireball disintegrated high in the atmosphere, it released energy equivalent to the detonation of approx 20 tons of TNT. During a meteorite fall, much of the original rock, called a meteoroid, vaporizes in the atmosphere due to frictional heating as it plunges earthward between seven and 45 miles per second.visit www.ournewplanets.com
