Catalog of Fixed Stars

The Catalog of Fixed Stars is an astronomical listing of notable stars, documenting their positions, brightness, and other characteristics. Despite their apparent motion, these stars are considered "fixed" relative to each other, forming a celestial backdrop. Historically, such catalogs helped navigators and astronomers locate stars for orientation and study. Modern catalogs, like the Hipparchus or Tycho catalogs, use precise measurements from telescopes and satellites, providing detailed data for scientific research and navigation. Overall, it serves as a comprehensive record of the stars’ attributes essential for understanding our universe.
