Does anyone know if there is a mathematic relationship between the mass/diameter of a planet and its exosphere?

Two answers...
First, if *every* planet had the same amount of atmospheric pressure at it's surface, then you'd see a definite relationship... As it is, it's complicated by the density of gases, molecules, pressures, and even things like proximity to it's star - a hotter atmosphere reaches into space more so than a cooler one.
