Is sun rotating around world or is world rotating around sun ?

It depends actually. Where did you define your origin ? Assume that I defined origin of universe as myself my position will be (0,0,0). So any rotation transformation will not change my position. It means all of the other object will turn around myself. Ofcourse it is intuitive to chose sun as origin in first sense , but it is not necessary , same transformations could be applied without chosing sun as an origin. There could be some standart system , than we can represent any position in universe by 3 coordinates. We can easily calculate using its distance and angle. That is actually what OPENGL is doing
