Fictional info (?) Suggested name Yangleng Planet type Cold planet It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 28°K (-245°C), and has a complex, layered cloud structure with sulfur dioxide thought to make up the lowest clouds, and nitric oxide the uppermost layer of clouds. It is named after the deity Yangleng, the spirit of the sea. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to BD-11 4672, which reoccurs over the so-called synodic period approximately every 70 days. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. In 1887, images from Wayfinder 6 showed Yangleng as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold planets. Wind speeds can reach 117 metres per second.
