  Lunar dust particles are generated by hypervelocity impacts of interplanetary
micron-meteoroids onto the surface of the Moon, which seriously threatens the
security of explorations. Studying the lunar dust dynamics helps to understand
the origin and migration mechanism of lunar dust, and to provide the
theoretical guidelines for the orbital design of lunar space missions. This
paper reviews previous research on the lunar dust dynamics, including the
interplanetary impactor environment at the Earth-Moon system, the mass
production rate, the initial mass, speed and ejecta angle distributions, the
related space exploration missions, the dynamical model and spatial
distribution of dust particles originating from the lunar surface in the whole
Earth-Moon system.
