Help positioning the sun behind a part everytime player moves

Help and Feedback Scripting Support
#1

Im making a space themed game and i want to make a system that positions the roblox sun(the sun thats in the skybox) behind a part so it will make it so the skybox sun is always behind the part from wherever you are
here is an example of how it should work but i dont have the script i just show it by moving the sun by hand

it seems like i can move the skybox sun using clock time and geographic latitude where clock time is for up and down movement and geographiclat is for sideways movement
the current problem is i dont know how to make it like the calculations for it
