Best way to give the impression that a circle + texture is rotating

Hi everyone!

I want to generate "fake" 3D planets, something like (minus the clouds/moons/asteroids):

(Image from the game planetarium.)

I think using shaders could be the right way to do that.
It's the first time I'm going to use shaders and I wonder if you could help me by pointing myself to some lectures or tutorials.

Thanks for any help!

If it were me and the surfaces of the planets remain the same I would just use a simple looping animation instead. At least, that's just what I would do.
