Bright Star Catalog

The Bright Star Catalog is a list of the brightest stars in the night sky, compiled to aid astronomers and star-gazers. It includes detailed information about over 9,000 stars, such as their brightness, distance from Earth, and spectral type. The catalog was first published in the 20th century and serves as a useful reference for identifying stars, studying their properties, and understanding their positions in the sky. It helps both amateur and professional astronomers locate and explore these prominent celestial objects more easily.
