Immediately make a reservation that the asteroids that spin in our The solar system and pose a certain danger to the earth, much more than they are shown by Laboratory staff NASA’s jet movement, you just need to understand: this model developing, it demonstrates only known (open) near-Earth asteroids, not all available.
For example, at the beginning of the video you can see how many asteroids were discovered by astrophysicists of the Earth at the beginning of 1999, then – on the beginning of 2009, and finally – at the moment. Moreover, purely near-Earth space objects are marked in blue, including while yellow are the “pebbles” of the asteroid belt between Jupiter and Mars. Notice how much is open in two decades new asteroids: in 1999 they can be almost recounted, and today is some kind of huge bee swarm spinning near our “blue ball”. Scary, isn’t it?
However, astrophysicists themselves assure us that the chances of a collision Earth with serious space objects is not as large as seem at first glance, even though many asteroids we are not even known. At the same time, other scientists are sure that Earthlings are practically defenseless against the cosmic threat. For instance, ESA Detlef Koscchny, head of the near-Earth objects department says about this:
Despite the seeming swarm of open (visible on this video) of asteroids, there are actually one hundred times more, moreover, most of them have diameters from 100 meters to several kilometers. However, the greatest danger is just more small space objects that we don’t even have about representations, and they, nevertheless, are capable of destruction (in event of a fall to Earth) commensurate with disasters on a scale middle European country.
