| Suggested name | Dahete'gebyu |
| Planet type | Cold gas giant |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
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 105°K (-168°C) at night to 350°K (77°C) during the day across the equatorial regions.
It is radically different from Earth in other respects. The atmospheric pressure at the planet's surface is 80 bar, or roughly the pressure found 1080 m under the oceans of Earth.
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). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.
