The answer is that the actual shape of the planetary orbit around the sun is elliptical.
Explanation:
The actual shape of the orbit of a planet around the sun is elliptical.
The assumption made by the Newton regarding the shape of an orbit of a planet around the sun was that the orbit of a planet around the sun is 'circular'.
Answer: All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. The orbits of comets have a different shape.
Explanation: Orbit and rotation
The elliptical orbit of Jupiter is inclined 1.31° compared to Earth. Because the eccentricity of its orbit is 0.048, Jupiter is slightly over 75 million km nearer the sun at perihelion than aphelion.
