Q. Which of the following scientist had proven that every planet has an elongated path?
✅ Correct Answer: (D)
Kepler
Explanation: Johannes Kepler formulated the Laws of Planetary Motion, which describe how planets move around the Sun. His first law, known as the Law of Ellipses, states that:
"The orbit of every planet is an ellipse with the Sun at one of the two foci."
Galileo (A) contributed to observational astronomy but did not define planetary orbits.
Newton (B) formulated the laws of motion and universal gravitation but did not discover elliptical orbits.
Copernicus (C) proposed the heliocentric model but believed planetary orbits were circular.
