| Suggested name | Youxyao |
| Planet type | Huge cold gas giant |
| Youxyao is similar in composition to Mweisei, and both have different bulk chemical composition from that of the larger huge cold gas giants. For this reason, scientists often classify Youxyao and Mweisei as "huge cold gas giants" to distinguish them from the other planets. The planet is named after the deity Youxyao, the goddess of the sea.
It has the densest atmosphere of the two huge cold gas giants, consisting partly of hydrogen chloride.
The rotational period and seasonal cycles of Youxyao are likewise similar to those of Earth, as is the tilt that produces the seasons. Youxyao is the site of Celestium Mons, the most active volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system. |
