With the exception of the innermost planet Mercury (which possesses a surface-bounded exosphere, similar to that observed on the Moon), all the planets in the solar system (and a few planetary satellites) are surrounded by detectable atmospheres. All the planets with atmospheres absorb ultraviolet...

This thin layer of air makes life on earth possible. Planets such as Mars with a smaller mass and consequently a weaker gravitational attraction have a more tenuous atmosphere than ours, while yet smaller heavenly bodies such as our moon cannot retain a gaseous shell at all. This is in ...
Aims. We present a self-consistent interior–atmosphere model to constrain the volatile mass fraction, surface pressure, and temperature of rocky planets with water and CO2 atmospheres. The parameters obtained in our analysis can be used to predict observations in emission spectroscopy and photometry ...
atmosphere [Gr.,=sphere of air], the mixture of gases surrounding a celestial body with sufficient gravity to maintain it. Although some details about the atmospheres of other planets and satellites are known, only the earth's atmosphere has been well studied, the science of which is called ...
