| Suggested name | Daiya |
| Planet type | Hot gas giant |
| In English, Daiya is often referred to as the "white planet" because the carbonyl sulfide prevalent on its surface gives it a slight white appearance that is distinctive among the astronomical bodies visible to the naked eye.
When viewed from Kanu Jin, Daiya can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. Daiya's atmosphere is similar to Kanu Jin's in its primary composition of carbon dioxide and carbonyl sulfide, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This planet is named after the deity Daiya, the demon of fear.
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 110°K (-163°C) at night to 630°K (357°C) during the day across the equatorial regions.
Liquid water cannot exist on the surface of Daiya due to low atmospheric pressure, which is less than 5 percent of Earth's, except at the highest elevations for short periods.
A prominent result is the "great orange spot", a giant storm that is known to have existed for centuries since it was first seen by telescope. |
