I'm trying to solve a problem related to the solar wind pressure at jupiter but I'm stuck at calculating the density. It is stated that the solar wind has a density of 5 [itex]cm^{-3}[/tex] and a speed of 400 km/s at the orbit of the Earth, and that it should be assumed that it propagates with constant velocity. Is the density of the solar wind at jupiter just

[tex]\rho_J = \rho_E \frac{S_E}{S_J}[/tex]

where S is the surface area of a sphere centered on the Sun?
