| Suggested name | Kichi |
| Planet type | Small hot gas planet |
| In English, Kichi is often referred to as the "white planet" because the ozone prevalent on its surface gives it a dark white appearance that is distinctive among the astronomical bodies visible to the naked eye.
The planet is named after the deity Kichi, the goddess of fear.
At this time it may appear as a bright star-like object, but is often far more difficult to observe than Yuya-myafu'ge.
Kichi is gravitationally locked with NGTS-4 in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 130°K (-143°C) at night to 945°K (672°C) during the day across the equatorial regions.
Kichi 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 Yuya-myafu'ge, Kichi has been a prime target for early extra solar exploration.
The smooth Borealis basin in the northern hemisphere covers 15 percent of the planet and may be a giant impact feature.
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 9 meters.
Surrounding Kichi is a thin planetary ring system and a powerful magnetosphere.
Observations from Earth have shown seasonal change and increased weather activity as Kichi approached its equinox 4 years ago. |
