Kepler

Kepler refers to Johannes Kepler, a German astronomer and mathematician from the 17th century, known for his significant contributions to our understanding of planetary motion. He formulated three fundamental laws: planets orbit the sun in elliptical paths, they sweep out equal areas in equal times, and their orbital periods are proportional to their distances from the sun. These laws were crucial in supporting the heliocentric model of the solar system and laid the groundwork for Isaac Newton's theory of gravity. Kepler's work was instrumental in the transition from classical astronomy to modern astrophysics.
