Abstract
The paper considers the asteroids approach to the Earth, for which collisions with our planet in the XXI century are possible. Close encounters on trajectories leading to collisions can often be found more than on nominal trajectories. Close encounters provide an opportunity to use the effect of a gravitational maneuver to prevent an asteroid from collisions with the Earth. As a result, the deflection of the asteroid can be carried out by the impact which is by several decimal orders less. Such an impact can be basically implemented using modern space technology. The asteroids approach to the Earth also helps to detect these asteroids, to refine their orbits from observations and to predict the characteristics of their possible collisions with the Earth in the future. In this paper, we consider the approach on the trajectories leading to collisions with the Earth for dangerous asteroids 2008 EX5, 2015 RN35, Apophis, which we have studied in detail.
