An asteroid known as 2012 DA14 was due to make a remarkably close approach, coming within 17, 200 miles of Earth surface hours later. NASA concluded that these two cosmic events are 'not related'. The two events were clearly coincidental, 'but a pretty amazing coincidence' Preliminary estimation size of the object before hitting the atmosphere was about 49 feet (15 meters) and had a mass of about 7,000 tons. The meteor, which was about one-third the diameter of asteroid 2012 DA14. Much of the mass burned up during atmospheric entry. Its trail was visible for about 30 seconds, so it was a grazing impact through the atmosphere. The fireball was brighter than the sun.
