Kepler's Laws
Kepler's laws revolutionized our understanding of planetary motion, providing fundamental principles that laid the groundwork for modern celestial mechanics. Johannes Kepler, a pioneering astronomer of the 17th century, formulated three laws that describe the orbits of planets around the Sun with remarkable precision. These laws not only challenged the prevailing geocentric model but also paved the way for Isaac Newton's theory of universal gravitation. In this introduction, we will explore Kepler's laws in detail, unraveling their significance in shaping our comprehension of the cosmos and their enduring relevance in contemporary astrophysics.
