The fate of sub-micron circumplanetary dust grains II: Multipolar fields

► Planetary magnetic fields affect the orbits of Kepler-launched dust grains. ► We explore the dynamics of grains at Jupiter, Saturn, Uranus, Neptune and Earth. ► Non-zero launch impulses have little effect on orbital stability. ► Lorentz resonances can destabilize motions causing negative grains to escape. ► We explore the sensitivity of dust grain orbits to time-variable charging.
