| Suggested name | Byukachu |
| Planet type | Hot gas giant |
| 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 85°K (-188°C) at night to 525°K (252°C) during the day across the equatorial regions.
A prominent result is the "great yellow spot", a giant storm that is known to have existed for centuries since it was first observed by radar. |
