Fictional info (?) Suggested name Hanangk Planet type Cold planet Hanangk has been known to astronomers since antiquity. Hanangk is similar in composition to Yangd, and both have different bulk chemical composition from that of the larger cold planets. Hanangk's atmosphere is similar to Yangd's in its primary composition of hydrogen deuteride (HD) and ozone, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Hanangk, the goddess of chaos. The smooth Borealis basin in the northern hemisphere covers 26 percent of the planet and may be a giant impact feature.
