has disposition location of overlaps site outer space astronomical body magnetosphere Magentospheres are generated by the motion of active hot iron and nickle or metallic planetary cores or by the interactions of plasma in stars.. The magnetic field near the surface of many astronomical bodies resembles that of a dipole. The field lines farther away from the surface can be significantly distorted by the flow of electrically conducting plasma emitted from a nearby star. The structure and behaviour of magnetospheres depend on numerous variables, including the type of astronomical body which generates it, the period of the object's spin, the properties of the axis about which the object spins, the axis of the magnetic dipole, and the magnitude and direction of the flow of stellar wind. A site in which charged particles are influenced by an astronomical body's magnetic field. The original definition referenced astronomical objects, however, the text suggests that reference to an astronomical body is more accurate. cosmic ray shielding disposition
