Triton

Triton is one of the largest moons that is apart of the Neptune system. It is one of the coldest worlds in the Solar System. Its surface temperature is near Absolute Zero. Triton has ice geysers which literally blows ice into the depths of space. Oddly enough, this moon is one of the least populated Neptunian worlds because of the lower classes that lives there and the economic demand for ice for other worlds that are very hot like Io. This world is also home to many scientists who tries to study the layers of Triton and what makes it very cold compared to many other worlds in the Solar System. Most of the populace on Triton are scientists who are there to investigate new subject matters and are conduct experiments.
