Answer :
The true shape of planetary orbits was discovered by Johannes Kepler.
Here's a breakdown to explain why Kepler is the correct answer:
1. Johannes Kepler was a German astronomer who lived in the late 16th and early 17th centuries.
2. Kepler developed his three laws of planetary motion, known as Kepler's Laws, which describe the motion of planets around the Sun.
3. Kepler's first law states that planets move in elliptical orbits with the Sun at one of the two foci of the ellipse, debunking the previously held belief that planetary orbits were perfect circles.
4. This breakthrough in understanding the true shape of planetary orbits was a significant contribution to the field of astronomy and laid the foundation for Isaac Newton's laws of motion and universal gravitation.
In summary, Johannes Kepler is credited with discovering the true shape of planetary orbits, which are elliptical, not circular. His work revolutionized our understanding of celestial mechanics and paved the way for further advancements in the field of astronomy.
