It takes about 13.99 billion years for a galaxy to form.
Each individual object (such as a star) revolves around the galactic center according to the laws of celestial mechanics. As a result, the objects closer to the center of the galaxy take less time for a complete revolution than the objects further out; the galaxy rotation is differential, meaning it does not rotate as if it were a solid object.
