| Suggested name | Wanwang |
| Planet type | Hot planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 28°K (-245°C), and has a complex, layered cloud structure with nitrogen thought to make up the lowest clouds, and formaldehyde the uppermost layer of clouds.
As seen relative to the fixed stars, it rotates on its axis exactly two times for every two revolutions it makes around HD 46375 A. |
