Named 2013 EC, the asteroid is about the size of the space rock that exploded over Russia two and a half weeks ago, somewhere between 10-17 meters wide (the Russian meteorite is estimated to be about 15 meters wide when it entered Earth’s atmosphere). 2013 EC was discovered by the Mt. Lemmon Observatory in Arizona on March 2. . There is no chance this asteroid will hit Earth.
2013 EC will come within 396,000 kilometers from Earth, (246,000 miles, or around 1.0 lunar distances, 0.0026 AU.
The Moon’s distance from the Earth varies between 363,104 km (225,622 miles) at perigee (closest) and 406,696 km (252,088 miles) at apogee (most distant point).
