atmosfäärikaotust
Atmosfäärikaotust, sometimes referred to as atmospheric escape, is the process by which atmospheric gases escape from a planet's or moon's atmosphere and enter outer space. This phenomenon is driven by the kinetic energy of gas molecules within the atmosphere. If a molecule's velocity exceeds the gravitational escape velocity of the celestial body at its altitude, it can escape. Several factors influence the rate of atmospheric escape, including the body's mass and radius, its atmospheric temperature, and the composition of the atmosphere.
The primary mechanisms of atmospheric escape are Jeans escape and hydrodynamic escape. Jeans escape, named after
Atmospheric escape plays a significant role in the evolution of planetary atmospheres. Over geological timescales, it
