Has the speed of the earth been uniform in the past? Or, over time, the speed of the earth changes uniformly in certain seasons?
As you know, according to Kepler, the elliptical path of the earth's orbit around the sun depends on the location-spatial position during one year around the sun. And because the Earth's axis is 23.5 degrees and the position of the Earth and the Sun along the way depends on the Sun's gravity and the magnetic force between the Sun and the Earth. increases and when it reaches further apart in the elliptical path, the magnetism between the sun and the earth has less effect and the speed of the earth decreases and accordingly the season is formed according to Kepler. that when the earth and the sun are located in an elliptic path at a distance, because the sun shines directly to the northern ecliptic, perpendicular to the orbit of Ras al-Seztan, the summer season is formed, and even though it is far from the sun, because the speed of the earth's path is slower and the sun is perpendicular to the orbit of the Cancer head in northern Nicera during the summer season. But when the path of the earth reaches a position near the sun in its total elliptical path, and the magnetic current has a greater effect, the speed of the earth increases, and even though it is close, it is because the earth is tilted and the sun shines perpendicular to the orbit of the zenith. It is winter in the northern hemisphere and summer in the southern hemisphere.
So we conclude that the speed of the earth depends on various factors such as: space-place-position of the elliptical path around the sun. A magnetic force between the sun and the earth changes its shape in an elliptical path and maybe in the future a circle.
