Earth's rotation around the sun
Although the Earth rotates around the Sun at a speed of up to 29 km per second, we are not affected by it at all. This is because the centrifugal force resulting from the Earth’s rotation is small, given that the Earth’s orbit around the Sun is very large and its ray reaches about 150 km on average.
In addition, the effect of Earth's gravity, which contributes to the stability of the planet, is 1,800 times greater than the centrifugal force of the Earth's rotation around the Sun.
The Earth's rotation around the sun The Earth completes its rotation around the sun once in a full year, as this journey specifically takes 365.242199 days. This is the reason why there is a leap year that comes every four years and is 366 days, as it rotates at a very high speed, amounting to 108,000 kilometers. At one o'clock. The Earth's elliptical rotation around the sun changes the seasons, in addition to the succession of the four seasons, as the deviation of the Earth's axis of rotation around itself causes a change in the distance between the Earth and the sun. The dominant season also varies in both the northern and southern hemispheres depending on the arriving solar radiation, which depends on the inclination of the axis. Towards the sun, where winter prevails in the southern hemisphere when the Earth’s axis is tilted away, Then the season reverses after 6 months and the axis approaches the sun to dominate the summer season, and so on, alternating between the northern and southern hemispheres.
