​The Great Red Spot

​A giant storm that works its way around Jupiter.

​

​As a gas giant, Jupiter is mostly made of atmosphere-like material so the storm can be three times the size of Earth!

​

​

​Saturn is light!

​Being a gas giant, Saturn is already not very dense.

​

BUT the fact that it's made up of a lot of helium (think about party balloons) makes it even less dense than some of the other gas giants.
