star catalogues

Star catalogues are systematic lists of stars, detailing their positions, brightness, and other characteristics. These catalogues serve as essential tools for astronomers, enabling them to identify and study celestial objects. They contain information such as coordinates (like a map) and the distance from Earth. Some notable catalogues include the Hipparcos Catalogue, which focuses on stellar parallax, and the Bright Star Catalogue, which lists the brightest stars visible to the naked eye. Overall, these catalogues facilitate our understanding of the universe and help track changes in star positions over time.
