Newly Discovered Tunguska-sized Asteroid Will Pass Closely to the Earth In 2013

Spanish astronomers have discovered the asteroid 2012 DA14 with a diameter of about 50 meters, which will miss the Earth by 26,900 kilometers in 2013.

_The asteroid was discovered by the Spanish Observatorio Astronomico de La Sagra on February 23 and is between 40 and 95 meters in diameter - which is similar in size to the meteorite which hit the Earth in 1908 in Tunguska, Siberia, where large sections of forest were destroyed by it (see picture). The distance of 26,900 for the passing next year on February 15 is about twice the diameter of the Earth and less than the height of geostationary satellites.

Astronomers will continue to refine the asteroid’s orbit and the distance of its future meetings with the Earth.
