Astrometry is a branch of astronomy that focuses on measuring the positions and movements of celestial objects. This scientific discipline helps astronomers determine the distances to stars and planets, as well as their orbits and trajectories. By accurately tracking these movements, researchers can better understand the structure and dynamics of the universe. The techniques used in astrometry involve precise observations of stars and other celestial bodies, often utilizing telescopes and advanced imaging technology. One of the key goals of astrometry is to create detailed star catalogs, which serve as essential references for various astronomical studies, including the search for exoplanets and the study of galaxies.
