planetary atmosphere  

Définition

  • An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam', and σφαῖρα (sphaîra) 'sphere') is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Atmosphere)
