Near-optimal deflection of earth-approaching asteroids

Research output: Contribution to journalArticlepeer-review


The process of optimizing the deflection of dangerous asteroids is addressed. It is demonstrated that a near-optimal determination of the direction in which impulse should be applied to the asteroid, as well as the resulting deflection, can be found without any explicit optimization. The method is easily applied to the true, three-dimensional geometry of the problem.
