Purple planet has a small atmospheric effet out in space, but a strong atmospheric effect on the ground. Lime planet has a strong effect in space and on the ground. The red ball has a script which sets its airFrictionMult to the sum of two functions, one being the function for Purple planet's atmosphere, the other being for Lime planet. These functions have an identical structure, with slightly different numbers:
pos0, pos1: the positions of the planets
atm0, atm1: the atmospheric strength at 1 m above the limit radius
lim0, lim1: an arbitrary radius at which atmospheric strength approaches infinity, being under said radius can cause extreme behavior
_mult: the replacement airFrictionMult for the red circle
