| Suggested name | Hehyu |
| Planet type | Cold planet |
| This cold planet is named after the deity Hehyu, the demon of dreams.
Hehyu's surface appears slightly bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.
Hehyu is by far the hottest planet in its solar system, with a mean surface temperature of 761°K (488°C).
Its apparent magnitude reaches -3, which is surpassed only by Ryabyu'ha, Gyuseyo'pa, and Kepler-862. Optical ground-based telescopes are typically limited to resolving features about 195 kilometers across when Hehyu is closest because of Ryabyu'ha's atmosphere.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. |
