👉 Astrometry is a branch of astronomy that focuses on measuring and studying celestial objects such as stars, planets, and moons. It involves using mathematical tools to calculate distances between celestial bodies and determine their positions and movements. Astronomers use various techniques, including telescopes, satellites, and space missions, to measure the distance between celestial objects. They also study the motion of these objects and how they interact with each other in order to understand the behavior of the universe as a whole. Astrom
