 The atmosphere is 120km high, but realistically,​ the density drops off to zero out there, so we can half that to get a reasonable number for a "​dense"​ atmosphere. ​ Assuming an atmosphere of uniform density and an altitude of 60km, what percentage of a square km is this? The atmosphere is 120km high, but realistically,​ the density drops off to zero out there, so we can half that to get a reasonable number for a "​dense"​ atmosphere. ​ Assuming an atmosphere of uniform density and an altitude of 60km, what percentage of a square km is this?
