Here is the classic ""asteroid destroys Earth"" scenario. The momentum of the asteroid is beyond the forces that even thermonuclear bombs might apply to stop its approach. Assuming that you can apply only modest forces, where might they best be applied to result in a new acceleration that will, as they say, ""save the world""? Draw an arrow to show the best location on the asteroid to apply force so that it avoids hitting Earth.

The celestial entities are roaming around the free space, as the different planets has a level of gravity which it imposes on other free roaming objects inside the solar system or more over inside the universe.

As these celestial entities hold greater significance in shaping the whole system having a number of the planets and stars. The asteroids are considered as the belt of rocks or the large entities having masses equivalent to mountains.

While, some of these celestial entities lose there track and get lost out of there normal track inside the solar system. The pull of gravity pushes these celestial entities to come closer towards the planets.However, in the past there were a number of asteroids which caused some of the most catastrophic events that we ever know.
The asteroids are required to be avoided by any habitable place inside the universe but however lets say, we have an asteroid coming closer towards itself which will result in the catastrophic events on the target planet.
But, lets say that an asteroid is faced by the planet in a more specific direction then the asteroid will have to act on a more specific target or point of collision to cause some of the catastrophic events on the planet's surface. As the living beings are greatly damaged by the impact of the asteroids.
The point a which the center of mass, m of the planet is placed is considered to be the point at which the planet will feel more impact.
