Hipparcos Catalogue
The Hipparcos Catalogue is a star catalog created from data collected by the Hipparcos satellite, which operated from 1989 to 1993. It contains precise measurements of the positions, distances, and motions of over 118,000 stars, making it one of the most important astronomical databases.
This catalogue has significantly improved our understanding of stellar properties and the structure of our galaxy, the Milky Way. It provides essential information for various fields of astronomy, including stellar evolution and galactic dynamics, and serves as a foundation for further astronomical research and exploration.
