Physics from St. Petersburg figured out how to prevent the invasion of asteroids

Scientists from St. Petersburg know how to save the Earth from asteroids. For this you may use a space ship.

The scientific staff of the state University of St. Petersburg tried to figure out how to save the Earth from an invasion of asteroids. Calculate the trajectory of the object, they proposed a number of scenarios.

Small asteroids can’t seriously harm the planet, but the stones with a 300-metre in size and above can lead to disaster. Scientists report that the asteroid Apofis, which will approach the Earth within a few decades, will be a big danger, it could suffer one of the medium size European countries.

Physics serves to prevent the threat from affecting the asteroid spaceship. Make a change of trajectory, and the object will travel on a different route without hitting the Ground. Second, 100% mode of disposal space body, its complete destruction.
