On December 9, the MIT Massachusetts Institute of Technology published this animation, because it more or less illustrates what they have done, the researchers have dedicated themselves to searching for small asteroids, the smallest ever detected in the main asteroid belt that is between Mars and Jupiter, I like the Illustration because it gives us an idea of what we were seeing.
We were seeing large asteroids, but we couldn't see the small ones because they are difficult to capture. What the MIT researchers did was design a better detection method, which managed to identify 138 rocks, from the size of a bus to that of a stadium. football, that is, from a few dozen meters to several hundred meters.
Asteroids larger than 1 km are difficult to collide with the earth; they occur every several tens of thousands of years or every hundred thousand years, but the smaller ones, those measuring tens of meters, do impact the earth more often. perhaps two or three every century, there are known cases such as the 1908 impact in Tunguska Siberia that devastated an immense amount of thousands of square kilometers of forest the 2013 asteroid that disintegrated in the sky over
Chelyabinsk in Russia, was about 14 meters in diameter and the one in Tunguska, there is debate, they say that it would be between 100 to 150 meters in diameter depending on whether it was an asteroid or whether it was a piece of a comet.
And besides, I suppose that in the 20th century there would be some more event that occurred in the ocean, remember that the oceans cover most of the planet and many times we cannot detect what happens there, although this part is improving the issue of detecting asteroids.
Now the international team led by physicists from ME has designed this method and they want to improve it in order to detect smaller asteroids and in this way have a defense plan or at least detection plan in case any of them could come in collision path with the earth, there are many more of them and they are also a more likely risk.
