摘要: This paper provides an estimate of the average number density dust particles accumulated around Mars. As investigated earlier, submicron-sized grains (a < 1 μm) are perturbed by electromagnetic forces and solar radiation pressure so that they do not stay close to Keplerian orbit ejecting satellite. The lifetime these in vicinity Mars ranges from a few days hundred days. Their trajectories contained approximately spherical volume. For larger (1 μm ≲ 7 μm), is major loss mechanism fill disklike corresponding due this perturbation tens half Martian year. Dust with ≳ have relatively stable forming disk/torus Mars, their determined collisions satellite since its orbit. Despite short large volume which contains trajectories, comparable whose size between 50 μm. fact thought dominate escaping particles. We conclude sizes 0.5 will be most abundant environment.
