stellar catalog

A stellar catalog is an organized list of stars and their key information, such as their positions in the sky, brightness, and other characteristics. Astronomers create these catalogs to keep track of stars, much like a detailed map or directory, making it easier to study their properties, track their movements, and identify celestial objects. These catalogs are essential tools for navigation, research, and understanding our universe, allowing scientists to access consistent data about stars across different observations and time periods.
