Star Catalog
A star catalog is a comprehensive list of stars and celestial objects, typically organized by their positions in the sky, brightness, and other characteristics. Astronomers use these catalogs to identify and study stars, their distances, and their properties. Each entry usually includes vital information such as coordinates and magnitudes, allowing researchers to navigate the night sky accurately. Notable examples include the Hipparcos Catalog and the Henry Draper Catalog, which have significantly advanced our understanding of the universe. Essentially, star catalogs serve as valuable references for both professional astronomers and enthusiastic stargazers.
