Nicolaus Copernicus discovered why planets stay in orbit when he found that the planets revolve around the sun. He is credited with starting the Scientific Revolution through this discovery.
Kepler
Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
Johannes Kepler, a German astronomer, discovered that planets follow elliptical orbits around the Sun, rather than perfect circles. This discovery is known as Kepler's first law of planetary motion and was a significant advancement in our understanding of the solar system.

The astronomer who discovered that planets orbit the Sun in elliptical paths is Johannes Kepler. His work, particularly the first of his three laws of planetary motion, established that planets move in ellipses with the Sun at one focus. This groundbreaking discovery was published in his work "Astronomia Nova" in 1609. Kepler's laws fundamentally changed our understanding of celestial mechanics.

Johannes Kepler discovered that planets orbit the Sun in ellipses with varying eccentricities in the early 17th century. This became known as Kepler's first law of planetary motion and revolutionized our understanding of planetary orbits.
