Planetary Atmosphere


Planetary atmosphere refers to the layer of gases that surrounds a planet or a natural satellite. It is held in place by the planet's gravity and is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others depending on the planet. The study of planetary atmospheres involves understanding the composition, structure, and dynamics of the atmosphere. This includes the study of atmospheric pressure, temperature, and density, as well as the interactions between the atmosphere and the planet's surface and surrounding space environment. Planetary atmospheres play a crucial role in determining the habitability of a planet, as they regulate the climate and protect the planet from harmful radiation and solar wind.
