Astrometry
Astrometry is the branch of astronomy that involves measuring the positions and movements of celestial objects such as stars and planets. It encompasses the precise determination of the positions, distances, and motions of celestial bodies, as well as the study of their physical and chemical properties. Astronomers use astrometry to track the paths of objects in the sky, map out the structure of the universe, and study the dynamics of galaxies and star systems.
