ResumoThe consequences of the assumption that the magnetosphere of Jupiter corotates with the planet are examined. It is found convenient to divide the magnetosphere into two regions. The inner region is qualitatively similar to the magnetosphere of the Earth provided that the ratio of the scale height to the radius of Jupiter is much less than 112. The outer region is dominated by rotational effects. It is expected to be slightly flattened, with a density falling off as Br−1. The velocity distribution of the plasma becomes increasingly anisotropic with increasing distance. The corotating magnetosphere breaks up as a result of electrostatic microinstabilities at 7–8 radii, well inside the boundary with the solar wind.
