The meteor is falling and the world is going to end

"The meteor is falling and the world is going to end"

                    

                  This is the news that comes out every year in December. The earth is about to collapse. Is this true?

                These are the paths of asteroid meteorites that threaten the Earth. It has over 1400 meteorites that are more than 140 meters in diameter. But the trajectory shows that none of them will hit the earth in the next 100 years.

             Make a computer model of the asteroid's size, position, and course of motion, and see when and where it will arrive. Based on this, we can accurately trace the impact even hundreds of years later. It was made by NASA 15 billion years ago, all of the dinosaurs had died after a similar meteor crash On February 15, 2013, the fall asteroid at Chelyabinsk, Russia, was only about 20 meters in size.

          It was about 19 km / s faster than the speed of the meteorite! The reason why they are so fast is because they are so hot and blasted up into the atmosphere.

The blast here isn't really the villain. Instead the villain is the shockwaves that followed the explosion

 However, there are no meteorites that could threaten us in the near future.
