magnetosphere is the region of
space surrounding an
astronomical object in which
charged particles are controlled by that object's
magnetic field. Near the surface of many astronomical objects, the
magnetic field resembles that of a
dipole. Farther away from the surface, the field lines can be significantly distorted by the flow of electrically conducting plasma emitted from a nearby star (e.g. the
solar wind from the Sun).
