EARTH (NBC33) — A newly discovered asteroid came within 7,500 miles of Earth this afternoon.
The asteroid, 2011 MD, passed by Earth at around noon on Monday. It was between 15 and 60 feet in diameter.
An event like this happens once every six years according to the Jet Propulsion Laboratory.
A smaller asteroid actually struck Earth back in 2008.
