The atmosphere in this layer is sufficiently rarified for Satellite s to Orbit the Earth, although they still receive some Atmospheric Drag . Exobase, also called the '''critical level''', the lowest altitude of the exosphere, is defined in one of two ways: # The height above which there are negligible atmospheric collisions between the particles and # The height above which the constituent atoms are on purely ballistic trajectories. The exact altitude at which the exosphere ends and space begins is not well-defined, and attempting to attach a specific value to it is not particularly useful. SEE ALSO EXTERNAL LINK
