Are Kepler’s laws purely descriptive, or do they contain causal information? Why?

You may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?

According to Newton, two objects attracted by gravity actually both orbit around their common center of mass. That means: a the Sun is not orbiting because it's too big and too massive compared with Earth b the Sun is not orbiting because it's too far from Earth c the Sun is not orbiting because stars do not orbit d the Sun is orbiting but we can't clearly see it because it's too big and too massive compared with Earth
