'''Gas Giants''' are worlds composed largely of gases, that surround a solid core.{{Fn|1}} Their gasses are harvested by both the [[Imperium]]{{Fn|2}} and [[Tau Empire]]{{Fn|3}} through the use of their ships. The Imperium will also place permanent installations in the orbits of Gas Giants to make it easier to harvest and refine their gasses.{{Fn|4}} [[TyranidsTyranid]] [[hive fleet]]s also do minor harvesting of gas giants and comet clouds.{{Fn|9}} Some Gas Giants have breathable upper atmospheres, which allows the Imperium to use [[Anti-grav]] [[Mining Platform]]s and its atmospheric aircraft.{{Fn|5}}
