A newly found asteroid, named 2013 EC will pass just inside the orbit of the Moon on March 4, 2013 at 07:35 UTC. Asteroid 2013 EC is big about 8-17 meters , just about the size of the space rock that exploded over Russia on February 15, 2013. It was discovered by the Mt. Lemmon Observatory in Arizona on March 2, 2013.
2013 EC will come within 396,000 kilometers from Earth, (246,000 miles, or around 1.0 lunar distances, 0.0026 AU), inside the orbit of the Moon. 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). There is no danger of collision with our planet.
On February 28, 2013 another newly discovered space rock - Asteroid 2013 EB, flew the same distance - 1LD from our planet. Its size was estimated about 16 meters.
Gianluca Masi from the Virtual Telescope Project had a live view of the asteroid when it was about twice the distance of the Moon, and a replay of that webcast is available below.
