Astrometry is the branch of astronomy that involves measuring the positions and movements of celestial objects, such as stars, planets, and galaxies. This field focuses on accurately determining the positions, distances, and motions of objects in space, as well as studying their interactions with each other. Astrometry plays a crucial role in a wide range of astronomical studies, from understanding the structure and dynamics of the universe to predicting the orbits of asteroids and comets. This research area has contributed significantly to our knowledge of the cosmos and continues to be an important tool in modern astronomy.
