An aerostat (From Greek ??ρ aer (air) + στατ?? statos (standing) through French) is a craft that remains aloft primarily through the use of buoyant lighter than air gases, which impart lift to a vehicle with nearly the same overall density as air. Aerostats include free balloons, airships, and moored balloons.
