Which of the following scientists formulated the laws of planetary motion?
A. Isaac Newton
B. Johannes Kepler✓ Correct Answer
C. Galileo Galilei
D. Nicolaus Copernicus
💡 Solution & Explanation
Johannes Kepler formulated the three fundamental laws of planetary motion between 1609 and 1619, utilizing precise observational data gathered by Tycho Brahe regarding the orbits of planets around the Sun. Isaac Newton later used these laws to derive his universal law of gravitation, while Copernicus proposed the heliocentric model without empirical mathematical laws of motion. Kepler's first law establishes that planetary orbits are elliptical rather than circular. These principles revolutionized Renaissance astronomy and physics.
