Asteroid named 2009 DD45 diameter of about 21 to 47 meters, flying over our planet to 13h44 on two thirds in GMT (6h44 by now Hanoi). The distance between the Earth is approximately 72,000 km, with one fifth the distance between the globe and the moon.

Scientists from the Siding Spring Survey, the program searches objects near the Earth in Australia, see it from 29 / 2. Then center of the asteroid International Astronomical Union has confirmed the presence of meteorites and classified it into objects in the solar system.

As data center asteroid before 2009, the object appears DD45 bay Monitoring Earth is an asteroid with a diameter of about 6 meters. This way our planet about 6500 km in March 2004.
In 1908, an asteroid the size equivalent to 2009 DD45 has exploded over Siberia in the Russian sky. With the power of the atomic bomb in 1000 that the U.S. threw the city of Hiroshima (Japan) in 1945, it fell 80 million trees in an area 2,000 km square area near the Tunguska River.

Many experts assert the asteroid the size of approximately 2009 DD45 can generate the equivalent power of 15 million tons of TNT explosives on the planet and if they are green. However, the extent of destruction of 2009 DD45 depends on the type of material makes it and tilt angle between the line of its flight and ground.
