. Planetary scientists from Colombia have calculated the probability of falling asteroids throughout the Land and came to the conclusion that such danger threatens the Equatorial countries of Africa, Asia and America and the North of Russia and Europe, said in an article posted in the electronic library arXiv.org

«Over the last century humanity has witnessed the fall of two major falls of meteorites of the Chelyabinsk and Tunguska meteorite. Unlike other disasters of this kind, which certainly occurred in earlier historical periods, these of a celestial body exploded over sea and over land, and they were watched by hundreds of people, some of whom even became their victims. What is most interesting, their epicenters are separated by only 2,300 kilometers,» says Jorge Zuluaga (Jorge Zuluaga) from the University of Antioquia in Medellin (Colombia)

In the last few decades, scientists around the world actively monitor the near-earth asteroids and hold a kind of cosmic «census» among them, trying to understand how dangerous they are for humanity. Asteroids in near-earth space there are so many that astronomers had to create a special scale to assess how likely they fall to the Ground.

By far the most popular and used two of these scales – the Palermo and Turin, created within the walls of MIT and the jet propulsion Laboratory of NASA. Both of these scales cityat the probability of the asteroid and the force of his explosion, but do not show, what will be the consequences of his landing.

According to Zuluaga, a small distance between the points of fall of the Tunguska meteorite and the Chelyabinsk fireball caused him to think not only about the frequency of falling of large meteorites and their implications, but also on what point on the Earth’s surface is more exposed to such danger.

The earth, as the scientist, is not the only inhabitant of the Solar system – it is surrounded by other planets and many small and large asteroids are distributed across space is not random. For this reason, «visitors from space» will be more likely to visit those corners of the Earth, which are now «watching» on the already known places of a congestion of small celestial bodies.

Following this idea, Zuluaga and his colleague Mario Scarcia (Mario Sucerquia) has created a unique computer model of the Solar system, in which the role asteroids played a kind of «rays of light» moving from Earth in the direction of clusters of real celestial bodies, and not Vice versa. This approach, as noted by the astronomer allowed us significantly to speed up the calculations and to hold them at a relatively modest supercomputer.

Using this model, Sparkia Zuluaga and counted how often an asteroid the size of Tunguska or Chelyabinsk meteorite should fall on the Ground and identified the hazardous and safe areas on its surface.

Overall, as scholars have noted, least of all such disasters will threaten the Equatorial and tropical regions of the world – Southeast Asia, Central Africa and South America, and more likely to affect polar and temperate latitudes of Europe, Russia and Canada. On the other hand, the position of the «hotbeds of the danger of meteorites» will be constantly shifting as time progresses, so that each region of the planet may become a victim of space rock.

Interestingly, these calculations indicate that neither of the Chelyabinsk meteor, the Tunguska nor his cousin were not in the same «hub» in that moment, when they fell to the Ground. This suggests that a small distance between the points of their fall was a coincidence, not a pattern, as originally suspected Zuluaga, and that the fall of a large asteroid does not necessarily occur where the likelihood of such a catastrophe the maximum in the current time.
