Astrometric methods look for minute changes in a star's position against a background of many other stars. Some stars, if observed repeatedly over time, show a perturbation or "wobble" in their proper motion. Since the sun has more mass the center will be much closer to the sun, but the sun still must move around this center, even though it will be an extremely small orbit.
