Hydrodynamic Escape

(Hydrodynamic Gas Loss)
(ongoing escape of gas particles from atmosphere)

Hydrodynamic Escape (or Hydrodynamic Gas Loss) is loss of part of an Atmosphere due to some molecules reaching escape velocity, i.e., those in the higher-velocity end of the Maxwell-Boltzmann Distribution, the distribution of speeds of the particles making up a gas (the distribution has a range and a peak, and "tails" with fewer and fewer particles moving at faster and slower speeds, but with non-zero probability of reaching any particular speed, e.g., the escape velocity).
