| Suggested name | Yechyu |
| Planet type | Terrestrial |
| This terrestrial is named after the deity Yechyu, the bringer of the underworld.
Yechyu's axis has the smallest tilt of any of its solar system's 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 125°K (-148°C) at night to 560°K (287°C) during the day across the equatorial regions.
The smooth Borealis basin in the northern hemisphere covers 23 percent of the planet and may be a giant impact feature.
Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
The largest moon is crowded with small earth-like herbivores known as "Woyyuan". They feed only while eating something called Qeng Wob. They are similar to the Aocye Zhwang but have 2 tentacles and vary in length from 50 to 80 cm. Woyyuan can survive temperatures from 30 to 90°C and sometimes the acidic environment which is rare on this planet. |
