| Suggested name | Kezefu-haiofu |
| Planet type | Cold planet |
| It is a cold planet planet with a mass one-thousandth that of Kepler-233, but two-and-a-half times that of all the other planets in its solar system combined. Kezefu-haiofu's atmosphere is similar to Nyae Chika's in its primary composition of sulfur dioxide and methane, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The planet is named after the deity Kezefu-haiofu, the demon of hate.
Kezefu-haiofu's surface appears very bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.
Kezefu-haiofu is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
As the closest planet to Nyae Chika, Kezefu-haiofu has been a prime target for early extra solar exploration.
The rotational period and seasonal cycles of Kezefu-haiofu are likewise similar to those of Nyae Chika, as is the tilt that produces the seasons.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 18 meters.
Kezefu-haiofu is primarily composed of sulfur dioxide with a significant part of its mass being methane, though methane comprises only about a limited amount of the number of molecules. A prominent result is the "great gray spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
Kezefu-haiofu has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Daedalus flyby missions and later by the Hotchins orbiter.
Like the other cold planets, Kezefu-haiofu has a ring system, a magnetosphere, and numerous moons, Ryunune Yucho being the least visible one. The Kezefu-haiofu 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. |
