if you type:
orbit view into the console, you will see orbital simulation details

if you type
orbit debug you will enable debug keys. Using the numpad up/down, you can change latitude, and left/right will change your longitude, which will change how the sun rises and sets.

Note now the sun will be positioned based on the position of your planet in its stellar system - so that means the motion of the sun will be based on your position using Kepler's Laws of Planetary Motion.
