Damped movement

I would like to rotate a smaller sphere around a larger sphere. so far no problem.

When the larger sphere moves the smaller sphere should react on this movement, something like a rubber band or delay to the movement of the larger sphere.

perhaps you must implement a sort of “spring”.
or use a physics engine to avoid rewriting code, something like ofxBullet, ofxMSAPhysics.

joint example ofxbullet:
