Washington Double Star Catalog

The Washington Double Star Catalog is a comprehensive database that records details about binary star systems—pairs of stars orbiting each other—observed from Earth. Created by astronomers, it includes information such as star positions, brightness, separation distances, and orbital characteristics. This catalog helps scientists study how stars form and evolve, and provides valuable data for understanding stellar behavior. It serves as a vital resource for astronomers and researchers aiming to map and analyze binary stars across the night sky.
