Atmosphere

An atmosphere was a collection of gases that surrounded a celestial body with sufficient mass, and therefore enough to cause gravitational attraction. Examples included planets, moons, and large asteroids. Almost all species in the galaxy required a form of atmosphere to breathe. Humans, as well as most other species, were known to breathe oxygen.

Moisture farms used vaporators to draw water from a planet's atmosphere.

The planet Quarzite had a strong atmospheric pressure that was capable of crushing starships and flattening beings.
