Near-Earth asteroid 2011 MD passed only 12,000 kilometers (7,500 miles) above the Earth's surface on Monday June 27 at about 9:30 EDT. The asteroid was discovered by the LINEAR near-Earth object discovery team observing from Socorro, New Mexico. This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicated there is no chance it will actually strike Earth. If a rocky asteroid the size of 2011 MD were to enter Earth's atmosphere, it would be expected to burn up high in the atmosphere and cause no damage to Earth's surface.
