Neptune - "The eighth satellite in the Sol system, Neptune is a gaseous planet composed primarily of hydrogen and helium, with traces of hydrocarbons and nitrogen. It has a mass of 1.0243×1026 kg, and it is the densest planet in its system. It is host to exceedingly severe storm systems visible from space, with windspeeds that nearly break the sound barrier. Neptune also has 13 satellites, and its smallest moon is believed to actually be a space station. Its notably blue hue is due to traces of methane gases in its upper atmosphere, the remnant of a failed terraforming experiment by Yakashians. The surrounding planets are noticeably void of any advanced lifeforms, with the sole exception of several cetacean species that inhabit the salt oceans of Gaia."
