what happens when an asteroid come to the earth what are the some of the precautions that can do to lessen the adverse effect from the impact​

Sagot :

Answer:

Defending the Earth from dangerous asteroid and comet impacts takes five steps, all of which need to happen concurrently.

1.Find

FindIf we don’t know an asteroid is there, we can’t prevent its impact. The further ahead of an impact we find a threatening asteroid, the more options exist to change its orbit so it won’t hit the Earth.

2. Track

We need to track it – get lots of telescopic observations over days, months, and years, each of which helps us refine the predicted orbit of the asteroid.

3.Characterize

To both understand specific asteroids in case we need to deflect them, and to more broadly understand the asteroid population, we need to characterize the asteroids.

4.Deflect

There are a variety of possible asteroid deflection techniques in various states of readiness, but all need more development and testing.

5.Coordinate and Educate

When you deflect an asteroid, as you move the target point off the Earth, you move it across the Earth first, so an asteroid targeting London might need to have its target point cross, say, Moscow on its way to getting it off the Earth.
