Fictional info (?) |
Suggested name | Saiwair Yu |
Planet type | Terrestrial |
This planet is named after the deity Saiwair Yu, the bringer of nature.
There are ongoing investigations assessing the past habitability potential of Saiwair Yu, as well as the possibility of extant life.
Optical ground-based telescopes are typically limited to resolving features about 180 kilometers across when Saiwair Yu is closest because of Earth's atmosphere.
In 2284, images from Frontier 6 showed Saiwair Yu as an almost featureless planet in visible light, without the cloud bands or storms associated with the other terrestrials. |
