1959 T. Gold in Jrnl. Geophysical Res. 64 1219/1 The region above the ionosphere in which the magnetic field of the earth has a dominant control over the motions of gas and fast charged particles..is known to extend out to a distance of the order of 10 earth radii; it may appropriately be called the magnetosphere.
