Neptune is the smallest gas giant in the Sol System and the last planet before the Kuiper belt worlds.
It is classified as a frozen N-Class world. Neptune has a total of 14 moons as well as a small ring system.
There are 8 floating cities within the atmosphere of this world, much like Uranus.
Its largest moon,Triton, is a minor human colony.
Like the other gas giants, Neptune's atmorphere is composed largely of hydrogen. Near the core, pressures reach nearly 100 thousand times Earth's.
Its core is composed of water ice and some other unknown metals. Note that the pressure at the core creates a temperature of up 80 degrees Kelvin.
