While supermassive black holes reside at the centers of most, if not all, large galaxies, including our Milky Way, galaxies themselves do not orbit these black holes. Instead, the stars, gas, and dust within a galaxy orbit the center of mass of the galaxy, which includes the black hole and other matter. These orbits form the characteristic spiral, elliptical, or irregular shapes of galaxies.

Galactic structures are held together by the gravitational forces exerted by the collective mass of all the stars, gas, and dark matter within them. The presence of a supermassive black hole at the center of a galaxy can influence the dynamics near the galactic core but does not directly cause the entire galaxy to orbit around it.

It's important to note that the study of galactic dynamics and the role of supermassive black holes is an ongoing area of research, and our understanding may evolve as we continue to make observations and gain insights into the intricate structures and behaviors of galaxies.
