Fictional info (?) Suggested name Sesunyu Planet type Small warm gas planet This small warm gas planet is named after the deity Sesunyu, the bringer of the sky. Two spacecraft have visited Sesunyu: Daedalus 9 flew by 27 years ago; and Messenger, launched 14 years ago, orbited Sesunyu over 105 times in four years before exhausting its pwoer source and crashing into the planet's atmosphere 10 years later. As one of the most prominent objects in the sky, Sesunyu has been a major inspiration in native culture for as long as records have existed. Sesunyu can easily be seen from Ryakyo Toekya with the naked eye, as can its whiteish coloring. Optical ground-based telescopes are typically limited to resolving features about 255 kilometers across when Sesunyu is closest because of Earth's atmosphere. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.
