NASA has released the images of the huge asteroid that passed near earth just last week. These images were generated by NASA's Goldstone Solar System Radar on the night of February 15 to February 16, 2013. They consist of 73 frames looped together. The asteroid, which is half the size of a football field, passed closer to Earth than any other known object of its size last Friday, the same day an unrelated and much smaller space rock blazed over central Russia, creating shock waves that shattered windows and injured 1,200 people. Asteroid DA14 blazed past the planet at about 8 miles (13 km) per second. At that speed, an object of similar size on a collision course with Earth would strike with the force of about 2.4 million tons of dynamite, the equivalent of hundreds of Hiroshima-type bombs.
