A newly found asteroid will pass by Earth at about the distance of the moon's orbit on Monday.
Its name is 2013 EC, and was discovered by the Mount Lemmon Observatory in Arizona on Saturday. It is roughly the size of the space rock that exploded over Russia two and a half weeks ago, measuring somewhere between 10 and 17 meters (33 to 55 feet) wide. The asteroid that sparked the Russian meteor is estimated to have been about 17 meters wide when it entered Earth’s atmosphere.There is no chance this asteroid will hit Earth.
