Fictional info (?)
Suggested nameXoxangb Yan
Planet typeLarge cold gas giant
Xoxangb Yan and Yingl'a are large cold gas giants rich in rock. When viewed from Yingl'a, Xoxangb Yan can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. Xoxangb Yan is similar in composition to Yingl'a, and both have different bulk chemical composition from that of the larger large cold gas giants. This planet is named after the deity Xoxangb Yan, the god of prosperity.

The hydrogen has probably photodissociated, and the free methane has been swept into interplanetary space by the solar wind because of the lack of a 2H2O layer.

The largest moon, Yonggew Wenzhyun, has a diameter greater than that of the planet Neptune.
