The NAAP Atmospheric Retention Module explores some of the elements that go into the retention or loss of an atmosphere by a planet. The Maxwell-Boltzmann velocity distribution and escape velocity are introduced.

First time users of NAAP materials should read the NAAP Modules – General Overview page.
