Solution

The first act to save the earth can be attacking the asteroid with the help of missile. A missile can break an asteroid into smaller pieces.
The second way is to change the path of an advancing asteroid. For changing the path of the asteroid, spaceship or missile can be used to push the asteroid aside. Space shuttle fitted with mirrors can be used. so that the reflected sunrays from such mirror can be bombarded on the asteroid. This will create the pressure on the asteroid and its advancing path can be changed.
By use of laser rays. the surface of asteroid can be subjected to evaporation. This will create change in the mass of asteroid. We can also send extra material on the asteroid from the earth. Such change in the mass of asteroid changes the orbit and the path of the asteroid.
By placing a space shuttle in vicinity of this asteroid, the gravitational force could be created. This can also change the speed and path of the asteroid. Astronomy and astrophysics are so much advanced now that even if such threat exists in future, we can easily protect our earth inhabitants well in advance.
