An atmosphere (New Latin atmosphaera, created in the 17th century from Greek ἀτμός "vapor" and σφαῖρα "sphere") is a layer of gases that may surround a material body of sufficient mass, and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low. Some planets consist mainly of various gases, but only their outer layer is their atmosphere.

    The meeting in the open of two dogs, strangers to each other, is one of the most painful, thrilling, and pregnant of all conceivabale encounters; it is surrounded by an atmosphere of the last canniness, presided over by a constraint for which I have no preciser name; they simply cannot pass each other, their mutual embarrassment is frightful to behold.
    Thomas Mann (1875–1955)

    The life of our city is rich in poetic and marvelous subjects. We are enveloped and steeped as though in an atmosphere of the marvelous; but we do not notice it.
