In this paper, the method of changing the trajectories of hazardous asteroids with orbits known for

some years to be on a possible collision course with the Earth is considered. The method relies on the use of

small asteroids (asteroidprojectiles) directed at hazardous celestial bodies by giving the projectile a suffi

ciently small velocity impulse ensuring the Earth gravity assist. As a result, the asteroidprojectile vector can

be controllably changed over a wide range. Apophis is considered as an example of the target asteroid. The

technical feasibility of this method is discussed. It is noted that despite the potential use of this elegant

method, its practical implementation requires further research and development.
