magnetosheath
The region between a planet's magnetopause
and the bow shock caused by the solar
wind. Within the magnetosheath, the magnetic field is turbulent, distorted,
weaker than the magnetospheric field, and deflected from an orientation
in the outer magnetosheath, which is similar to that of the interplanetary
magnetic field, to a draped orientation near the magnetopause. The particles
in the magnetosheath come from the shocked solar wind and have a density
that typically decreases from the bow shock to the magnetopause but always
remains higher than the magnetospheric plasma density. The Sun's magnetosheath
is known as the heliosheath.
