| Suggested name | Rwan |
| Planet type | Cold planet |
| This planet is named after the deity Rwan, the demon of the sky.
Two spacecraft have visited Rwan: Wayfinder 9 flew by 29 years ago; and Messenger, launched 11 years ago, orbited Rwan over 95 times in four years before exhausting its reactor and crashing into the planet's atmosphere 7 years later.
Two of Rwan's moons, Yuanlye and Chaoch-wangj, are are quite oddly shaped.
Optical ground-based telescopes are typically limited to resolving features about 420 kilometers across when Rwan is closest because of Nenxyang's atmosphere.
The Rwan system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. |
