06. RETROGRADE AND PROGRADE ROTATION OF PLANETS

Due to astronomical observations, we know that most of planets in our solar system revolve in the prograde direction – i.e. counterclockwise. And this direction of rotation coincides with the direction of rotation of the Sun. However, two planets in the solar system rotate in the retrograde direction – i.e. clockwise. Venus and Uranus rotate by such way.

Let's examine why not all planets of the solar system rotate in the same direction.

As already mentioned, the reason for starting rotation of each planet is an action of two factors – a tendency of the hemisphere heated by the star (the sun), to move away from it and an attraction of the opposite, cooler hemisphere by the Nucleus of galaxy. As already mentioned, the rotation of the planet began only when the planet was located “laterally” of the Sun (star) to the Nucleus of the Galaxy. So, prograde or retrograde the rotation of the planet became, it depended on only one factor. And namely from which “side” of the Sun the planet was located at the start of the rotation. We can conditionally defined designate one “side” of the Sun as a right, and other - as a left. For example, if you look at the Nucleus of Galaxy from the position of an observer on the Sun, then the “side” of the Sun on the right is the right and one on the left is the left.

So, if the planet at the start of rotation was on the right “side” of the Sun, then it began to rotate counter-clockwise – i.e. forward. Most of the planets in our solar system were in such situation. If the planet was located on the left “side” of the Sun, then it began to rotate in a clockwise direction – i.e. in the opposite direction. Venus and Uranus were in this strategy.

But why the planets did not change their direction of rotation after they were in the course of rotation around the sun on its other “side”.

And here's why.

The magnitude of the Force of Attraction that arises in any planet or satellite in the solar system composition in relation to the Nucleus of Galaxy is always less than the Force of Attraction that arises with respect to the Sun (i.e. to a star). And the reason for this is the difference in distances. The Nucleus of the Galaxy is very far. And so, even despite of its huge size (much larger than of the Sun), the magnitude of the Force of Attraction arising in relation to it, is less.

When the planet did not yet rotate, one its hemisphere completely turned to the sun, and another was completely away from it. This means that the turned away hemisphere did not “feel” attraction of the Sun (precisely because it turned away from it). There was only attraction of the Nucleus of the Galaxy. But once the heated hemisphere began to turn away from the Sun, starting thus the planet's rotation, at the same time the colder, turned away hemisphere began gradually to come back to the illuminated side. And once that happens, the Force of Attraction directed toward the Sun begins to act on it, and it is greater than the Force of Attraction to the Nucleus. As a result, after the rotation of the planet began, its direction does not change. And all because of that now, all time, when chilled on the night side area begins to come back to the illuminated side, the Gravity Field of the area forces this area to move in the direction of the Sun. And so, there is a rotation of the planet. We recall that on the illuminated side of a planet a Field of Repulsion is forming, and that, in fact, makes the heated area to move away from the Sun.

As you understand, we can talk about the prograde and retrograde rotation not only of planets, but also of stars and Galactic Nuclei.
