gas balloon
Buoyant sky vessel
A gas balloon is a balloon that achieves lift through a gas lighter than air—typically helium or hydrogen—rather than heated air.
The term distinguishes these from hot air balloons, which rise because warm air is less dense than cool air.
Gas balloons can stay aloft longer since they don't require continuous heating: The gas balloon drifted silently for hours.
