Simulation of a system for protecting earth from asteroid hazard by gravitational spacetug or solar sail

摘要

The present work is devoted two of the methods of protecting the Earth from asteroid's danger, namely, the use of the gravitational spacetug or solar sail. The mathematical model of control movement asteroid, solar sail or spacetug and Earth taking into account the gravity perturbation from all bodies including in system and the real position of celestial bodies. A software package the simulation and visualization of the trajectories is designed. The obtained simulation results confirm the possibility of the deviation of the asteroid from a dangerous trajectory by the use of modern spacecraft.
