| Suggested name | Ohon |
| Planet type | Huge cold 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 110°K (-163°C) at night to 595°K (322°C) during the day across the equatorial regions.
Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). |
