Head of the American National Space Agency Jim Brydenstein made an alarming statement that alarmed many earthlings.
The official warned that humanity should prepare for a destructive asteroid falling onto our planet. Hypothetical the threat, according to the director of NASA, is real, and many of us they don’t even know what danger can lurk all life on the ground.
Brydenstein reminded the world of Chelyabinsk a meteorite that thundered on February 15, 2013 over Russia. The specialist notes that the diameter of this celestial body was only about 20 meters, however, when entering the atmosphere of our planet, it exploded with a power 30 times the nuclear power the “Baby” bomb dropped on Hiroshima.
According to the American, the Chelyabinsk meteorite has become unique only that it exploded over the cities, causing noticeable destruction. Similar bodies of cosmic origin, they say, fall to Earth often enough, and, fortunately, tend to burn over the oceans and uninhabited parts of land.
However, computer simulations performed by scientists NASA shows that at least once every 60 years, meteorites will be appear over settlements, and 20 meters is far from the limit for their possible diameter. Just remember the fall Tunguska meteorite June 30, 1908 and a meteorite fall in Brazil on August 13, 1930. The diameter of the latter was at all from one to one and a half kilometers.

If such objects collapse on densely populated continents, victims will be disastrous. So, the 140-meter asteroid should be enough to destroy a middle European country.
Brydenstein calls on all states of the world to rally in the face of possible threat. However, what needs to be done to counter it, the head of NASA did not explain. Even if in advance detect “space wanderers” flying to Earth, escape from they will still be impossible. Destruction of asteroids by nuclear warheads, the installation of some colossal shields are for now pure fiction.
By the way, one of the most dangerous asteroids – 2007 FT3 at 340 meters in diameter, which can collide with our planet in early October of this year. So what can we oppose him? ..
