FAQ
Frequently Asked Questions
No. Celestial mechanics is a rigorous scientific field based on physics and mathematics. Astrology is a belief system with no scientific basis.
Johannes Kepler (laws of planetary motion), Isaac Newton (law of universal gravitation), and Pierre-Simon Laplace were foundational figures.
No. While it originated there, its principles apply to any system of bodies interacting via gravity, including binary stars and star clusters.
Yes. It is essential for space mission design (where it overlaps with astrodynamics), predicting satellite orbits, and understanding the long-term stability of planetary systems.
