Theoria Motus Corporum Coelestium

"Theoria Motus Corporum Coelestium," written by Johannes Kepler, is a foundational work in astronomy that describes the motion of celestial bodies, particularly planets. Published in the early 17th century, it presents Kepler's three laws of planetary motion, which explain how planets orbit the Sun in elliptical paths, with varying speeds, and how their distances relate to their orbital periods. This work helped shift our understanding of the solar system from a geocentric (Earth-centered) to a heliocentric (Sun-centered) model and laid the groundwork for Newton’s law of universal gravitation, influencing modern physics and astronomy.
