How Does Hipparchus's Work Relate to Modern Astrophysics?

In many ways, Hipparchus can be considered a pioneer of astrophysics. His emphasis on precise measurements and mathematical analysis laid the groundwork for the scientific method in astronomy. Modern astrophysics continues to build on his approach, combining observational data with theoretical models to understand the universe.
His discovery of the precession of the equinoxes is particularly relevant to modern astrophysics. Understanding Earth's precession is crucial for accurate celestial navigation and for interpreting historical astronomical records. It also has implications for climate science, as precession affects Earth's climate cycles.
