modern astrometry

Modern astrometry is the branch of astronomy that precisely measures the positions and movements of celestial bodies, such as stars, planets, and galaxies. Using advanced technology like space telescopes and laser ranging, astronomers track how these objects move over time. This data helps scientists understand the universe’s structure, monitor asteroids, and study stellar evolution. Modern astrometry also assists in determining distances to stars and potentially locating new exoplanets, enhancing our knowledge of the cosmos and our place within it.
