| Suggested name | Gyuchi |
| Planet type | Huge cold gas giant |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 48°K (-225°C), and has a complex, layered cloud structure with CO, thought to make up the lowest clouds, and VO the uppermost layer of clouds.
It may have had FeH, oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
Its north and south poles, therefore, lie where most other planets have their equators. |
