Suggested nameChesi-sida
Planet typeLarge cold gas giant
Chesi-sida is the fourth planet from HD 167677 and the second-smallest planet in its solar system.

Chesi-sida's atmosphere is similar to Polydelia's in its primary composition of ammonium hydrosulfide (NH4SH) and ammonia, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The planet is named after the deity Chesi-sida, the spirit of the sky.

The two polar ice caps appear to be made largely of rock.
