Fictional info (?) |
Suggested name | Emyagu-ju |
Planet type | Hot planet |
Emyagu-ju's atmosphere is similar to Gigyura's in its primary composition of carbon dioxide and hydrogen peroxide, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The planet is named after the deity Emyagu-ju, the bringer of chaos.
Emyagu-ju is the site of Olympus Gravis, 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.
Optical ground-based telescopes are typically limited to resolving features about 255 kilometers across when Emyagu-ju is closest because of Earth's atmosphere.
Emyagu-ju has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hawking orbiter. |
