astrometric catalogues

Astrometric catalogues are comprehensive lists of astronomical objects, like stars and planets, with precise information about their positions and movements in the sky. They serve as detailed reference guides that help astronomers accurately locate objects, study their motions, and understand the structure of our galaxy. These catalogues are created by analyzing observations from telescopes, often combining data over time to achieve high precision. They are essential tools for navigation, space missions, and advancing our knowledge of the universe’s organization and dynamics.
