What Does PPM Stand For?
PPM stands for Positions And Proper Motions Catalog
The Positions And Proper Motions Catalog (PPM) is a comprehensive astronomical database that provides precise positional measurements and proper motion data for a wide range of celestial objects, including stars and other stellar entities. This catalog serves as a valuable resource for astronomers and astrophysicists, facilitating the study of star movements, dynamics, and the structure of the Milky Way galaxy. The PPM contributes significantly to various research areas, including stellar kinematics, galactic evolution, and the identification of potential targets for further observational studies.
