Annotation
An equation is written for the general case of nonstationary gas motion in a spherically symmetric gravitational field. The equation solution corresponding to the steady-state radial flow in the medium is analyzed. It is shown that the characteristic lifetime of a planetary atmosphere depends exponentially on a parameter equl to the ratio of the product of the gravitational acceleration by the planet radius to the atmospheric temperature.
