Need help making a skybox material

I’ve been trying to make a day and night cycle with a custom skysphere and material. I managed to figure out how to transition night and day with a lerp, I also have a color to change the sky color. It all works with a variable called Time of Day which transitions day and night skys.

My questions are how do you render a moon/sun texture on a material for the custom skysphere?, also I want it to move depending on the time of day variable, another question is how can I get rid of the light coming from the sun on the skysphere? Example: Screenshot by Lightshot, another question how can I get clouds to render with the skybox texture and make it move, change density etc? my final question is how can I make an orange color appear at the horizon when it hits around sunset or sunrise with my time of day variable?

Does anyone have any ideas?
