The Gas Giants

The next in row four planets are not solid; although very large they only have solid core of silicon, nickel, and iron and thick atmosphere composed mostly of hydrogen and helium.

They all have names from the ancient Greek primordial gods:

• Jupiter; from god Zeus
• Saturn; from god Cronus
• Uranus; from god Uranus
• Neptune; from god Poseidon

Furthermore, the last two, Uranus and Neptune also called ice giants as they are mostly composed of water, ammonia and methane ices.
