The collision of space objects is normal and has been around since the birth of the solar system. In the birth of the solar system. There are countless collisions between objects, even if the world is already born. It also collided with a large object until the crust broke away. And become our moon. This is the theory of the moon. There are also theories of evolution, life on earth And the great extinction .... all come from the Impact event anyway.
Impact event starts with a normal collision. And it happens every day before. That is the collision of the meteorite itself. The collision of the meteorite is a collision with a random occurrence completely. There are no more areas to hit. And the collision occurs during the day and night, as well as the same in this image recorded during 1993 - 2013.
How much energy does a meteorite have? The energy of this meteorite is very severe because the two main variables are the meteorite mass. This is very high in the tens of thousands of tons and the velocity of the atmosphere is very high. 50 - 70 km / sec This makes the energy of it very high. But most of this energy is not. Relay down to earth on earth Because it burned in the floor before I lost it. This energy. Transmitted in the form of air blast, the characteristics of this air blast we are familiar. Well, from the explosion of various types of explosions, it can create shock waves that have a lot of power to destroy things. In case of this meteorite will occur in a very high position, about 50 - 80 km above the Earth. Or simply say, the energy of the meteorite. It's like we took several kilos Several megabytes go to the sky at an altitude of 80 km above the earth.
This table shows the energy of the meteorite produced. Show the equivalent amount of TNT.
