Which Scientist proved that the path of each planet around the Sun is elliptical ?

(1) Kepler
(2) Galileo
(3) Newton
(4) Copernicus

Correct Answer : (1) Kepler was the Scientist who proved that the path of each planet around the Sun is elliptical.

Explanation:

Johannes Kepler was the German scientist who proved that path of each planet around the Sun is elliptical, not in a circle.

He is the famous for giving Kepler’s three laws regarding planet’s motions.

According to Kepler’s First law (Law of Orbits), each planet revolves around the sun in an elliptic orbit, the sun occupying one of the Foci. Hence, Kepler was the Scientist who proved that the path of each planet around the Sun is elliptical.

The elliptical shape of the orbit is a result of the inverse square force of gravity. Kepler’s laws were derived for orbits around the sun, but they apply to satellite orbits as well.
