   Observational Astronomy and Cataloging
   Hipparchus is most famous for undertaking a systematic revision and expansion of early star catalogs, particularly those that followed the work of Aristarchus of Samos. His magnum opus in this area, $\Pi \epsilon \rho \iota \tau \tilde{\omega} \nu \dot{\alpha} \sigma \tau \rho \omega \nu \dot{\alpha} \pi \lambda \alpha \nu \tilde{\omega} \nu$ (On the Fixed Stars), compiled data on approximately 850 stars, assigning them positions, brightness (magnitude), and celestial coordinates.
