| Suggested name | Urenyo-bi |
| Planet type | Hot gas giant |
| When viewed from Daogyabyu, Urenyo-bi 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. Urenyo-bi's atmosphere is similar to Daogyabyu's in its primary composition of xenon and oxygen, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Urenyo-bi, the messenger of love and beauty.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
Urenyo-bi is the site of Ars Mountain, the tallest volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
Urenyo-bi is primarily composed of xenon with a significant part of its mass being oxygen, though oxygen comprises only about a tiny amount of the number of molecules. |
