The explanation offered by Newton was wrong.

A question arose as to why the planets orbit the Sun in an elliptical path.
As an answer to this question, Sir Isaac Newton rendered an explanation that the circular path of the planets change to an elliptical path due to the gravitational force of the other planets.
But, it has been proved with evidence that this explanation was wrong.
Particularly, Halley’s Comet, though stated to be revolving around the Sun once in seventy-five years, revolves around the Sun once in seventy-five to seventy-six years only.
When Halley Comet is revolving around the Sun in this way, it is believed that a minor change in the path of Halley Comet due to the gravitational force of Jupiter and Saturn is the reason for this change.
But, unlike Halley Comet, all the planets of the Solar System, including the earth, orbit the Sun in a fixed time span.
This proves with evidence that the explanation offered by Sir Isaac Newton, who stated that the elliptical path of the planets was caused by the disruption of the gravitational force of the other planets, was wrong.
