Fictional info (?)
Suggested nameNyin Qyan
Planet typeHuge cold gas giant
As seen from @STARNAME, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.

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 145°K (-128°C) at night to 1190°K (917°C) during the day across the equatorial regions.

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.
