Suggested nameNosa Gu
Planet typeCold gas giant
Orbiting within Xozo Sulu Da's orbit, Nosa Gu is an inferior planet and never appears to venture far from Kepler-539; its maximum angular distance from Kepler-539 (elongation) is 55 degrees.

Nosa Gu has been known to astronomers since antiquity. Nosa Gu's atmosphere is similar to Xozo Sulu Da's in its primary composition of carbon dioxide and ammonium hydrosulfide (NH4SH), but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The planet is named after the deity Nosa Gu, the god of destruction.

The smooth Borealis basin in the northern hemisphere covers 26 percent of the planet and may be a giant impact feature.

Its apparent magnitude reaches -3, which is surpassed only by Xozo Sulu Da, Uboh-ituv'u, and Kepler-539.
