Abstract : It is shown that the density of a planetary exosphere can be derived from the Boltzmann equation, provided the equation is modified to take into account the escape component. The solution is obtained through a perturbation method; the zeroth order solution is the barometric formula, which applies when escape is negligible. The solution gives only the total density (ballistic plus bound orbits). (Author)
