ASTEROID'S ATTACK

The asteroid impact that hit the surface of the earth resulted in a very severe impact. While the asteriod's orbit located between Mars and Jupiter remains a potential threat to the earth. We know that in the asteroid belt so many celestial bodies that are tens of times the size of the earth even some hundreds of times the size of the earth.
The impact of an asteroid that hit the Bering Sea region caused a tsunami wave. Ecosystem destruction also occurs due to the impact of this space rock. Ruins of buildings and fatalities are estimated to be very large. Given the size of the asteroid which is 10 times the size of the earth with speeds reaching 560 km / h, it is able to make large waves and on the land where it falls formed a giant hole. Nearly all buildings affected by the fall of the asteroid are level with the ground.
Since the incident took place off the east coast of Russia a few years ago, a giant explosion occurred above the Bering Sea when an asteroid with a circumference of about ten meters exploded with explosive energy ten times greater than the bomb dropped on Hiroshima.
These celestial bodies can be a threat because so far we have never had a record of when asteroids hit the earth. It is almost certain that we do not yet have the technology that predicts the asterisks. Fortunately, the fall of an asteroid or meteor is more like a place so that the risk of casualties is smaller. However, we still need to be aware of various types of celestial objects that fall and penetrate our atmosphere.
Space objects often escape from these belts, causing new debris to enter into an orbit across the planets. The inner solar system is filled with debris, ranging from small dust spots to comets and asteroids several kilometers in diameter.
Now researchers have begun to direct research into asteroid space into the earth. Joint efforts have been made to look for potentially dangerous objects that can hit Earth. The result is the identification of thousands of asteroids near the Earth with a height of several thousand kilometers. Once found, the orbits of these objects can be determined, and the path is predicted to the future, to see whether the impact of the collision is possible or not. The longer time we have in observing the object given, the better the prediction that is produced

there are a number of alternatives that are being developed to reduce the impact of the asteroid attack.

1. diverts the orbit of the asteroid
   2 destroy the asteroid while still approaching the Earth's atmosphere
   pulling the asteroid back into its orbit so it doesn't come out of the original orbit.
   i hope you accept my thought

thank you @xpilar
