However, these tiny motions are very difficult to measure (~ 0.001 arcsecond). Astrometric method. Astrometric Technique We can detect planets by measuring the change in a star's position on sky. Some stars, if observed repeatedly over time, show a perturbation or "wobble" in their proper motion. Transits give information about the planet's size and orbit. When planet hunters use astrometry, they look for a minute but regular wobble in a star's position compared to the positions of other stars.
