Suggested nameYaosyuan
Planet typeLarge hot gas giant
Its orbital period around TOI-4791 of 4.3 earth days is the shortest of all the planets in its solar system.

Yaosyuan is the only habitable planet orbiting TOI-4791 and one of the largest in its solar system. The interior of Yaosyuan is mainly composed of ices and stone. The planet is named after the deity Yaosyuan, the bringer of good fortune.

Yaosyuan is a large hot gas giant and is sometimes called Anjyan'syo's "twin planet" because of their similar size, mass, proximity to TOI-4791, and bulk composition.

The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 meters. In November 2500, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Yaosyuan.

Observations from Earth have shown seasonal change and increased weather activity as Yaosyuan approached its equinox 7 years ago.

The lakes are known for its large primitive herbivores known as "Yezweng". They spend their life hidden in craters by consuming a substance called "Dyiw Wad". The Yezweng are similar to the Endya-swenn but have 5 arms and vary in length from 8 to 17 mm. Yezweng are known to live at temperatures from 120 to 150°C and sometimes electrical shock which is common on this planet.
