Fictional info (?)
Suggested nameEnen Ewyf'ew
Planet typeHuge 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 60°K (-213°C) at night to 385°K (112°C) during the day across the equatorial regions.

Its north and south poles, therefore, lie where most other planets have their equators.
