Webbelow Earth’s escape velocity of 10.8 km/sec at the exobase. Yet hydrogen atoms still manage to escape because many move faster than average. This loss of particles from … WebThe dominant escape mechanism for atmospheric escape tends to be thermal, where the highest energy, hottest molecules/atoms in the atmosphere manage to reach escape velocity. Having a fairly deep gravity will like the Earth's precludes this happening for all but the very lightest gasses, like hydrogen and helium.

WebOr, the gas velocity must be less than 22.4 km/s, since Earth's escape velocity is 11.2 km/s. We could calculate a temperature at which an average hydrogen molecule would have a velocity of 22.4 km/s: v average (H 2) 22.4 x 10 5 cm/s = [ 3 x (1.38 x 10-16 gm cm 2 s-2 K-1) x T / (2 x 1.67 x 10-24 gm) ] 0.5 Earth Atmospheric escape of hydrogen on Earth is due to charge exchange escape (~60–90%), Jeans escape (~10–40%), and polar wind escape (~10–15%), currently losing about 3 kg/s of hydrogen. The Earth additionally loses approximately 50 g/s of helium primarily through polar wind escape.
