NASA warns, that the asteroid 2009 BD will sweep today at a distance of 345,000 kilometers from Earth, ie inside the orbit of the Moon, which happens rarely. The diameter of the asteroid 2009 BD is 10 meters, velocity will be 11.2 kilometers per second. Despite this small size of asteroid 2009 BD, researchers from NASA estimated, that in the event of a fall to Earth releasing energy, equivalent to the explosion of 7.8 tons of TNT. Asteroid 2009 BD is asteroid, moving around the Sun almost in tandem with Earth (see a photo). Orbit of asteroid 2009 BD is almost identical to Earth's orbit. Earth's gravity could capture asteroids before they begin delineate a giant spiral around the Earth. At the moment, little is known about the asteroid 2009 BD, despite the fact, that the asteroid 2009 BD was on 25 January 2009 at a distance of 644,000 kilometers from Earth. Eventually it will be possible to trace the orbit of asteroid 2009 BD with greater accuracy. Four known asteroids, which becomes a temporary "Moons": 2003 YN107, 2004 GU9, 2001 GO2, 2002 AA29. All they can routinely come closer to Earth.
