Ukrainian scientists discovered a large asteroid in late 2013 that could possibly strike the Earth on Aug. 26, 2032. If such a collision occurred, it would strike with a force 50 times greater than the largest atomic bomb.
The object, named TV135, is 1,300 feet or nearly a quarter of a mile wide. The impact of such an object would cause damage over an area of 100,000 square miles. However, the actual chance of TV135 striking Earth is only estimated at 1 in 63,000. On the Torino Scale, which is used to categorize the impact hazard of near-Earth objects, TV135 rates a 1 out of 10, which means a very small risk, but greater than zero.
