It is interesting that all the planets of the solar system do not stand still, but rotate in one direction or another. Most of them are “in solidarity” with the Sun in this regard. The celestial bodies spin back clockwise, as seen from the North Pole. The exceptions are Venus and Uranus, reversing. Moreover, if everything is clear with Venus, then the second planet has some problems with determining the direction, because Scientists have not come to a consensus on which pole it has is north and which is south because of the large inclination of the axis. The sun rotates around its axis at a speed of 25-35 days, and this difference is explained by the fact that at the pole the rotation is slower.

The problem of how the Earth rotates (around an axis) has several solutions. Firstly, some people believe that the planet rotates under the influence of star energy in our system, i.e. Of the sun. It heats the huge water and air masses that act on the solid component, providing rotation at one speed or another for large periods of time. Proponents of this theory suggest: the strength of the impact can be such that if the solid component of the planet is not strong enough, then continental drift can occur. In defense of the theory, it says that planets that have matter in three different states (solid, liquid, gaseous) rotate faster than those with two states. Researchers also note that on the approach to the Earth a huge power of solar radiation is formed, and the power of the Gulf Stream in the open ocean is more than 60 times the power of all rivers on the planet.

The most common answer to the question: “How does the Earth rotate during the day?” - there is an assumption that this rotation has been preserved since the formation of planets from gas and dust clouds with the participation of other cosmic bodies that crashed into the surface.

Representatives of various scientific (and not only) directions tried to find out what the rotation of the Earth around the axis is connected with. Some believe that for such uniform rotation certain external forces of unknown nature are applied to it. Newton, for example, believed that the world often “needed to be fixed”. Today it is suggested that such forces can operate in the area of ​​the South Sandwich Islands and at the southern end of the Verkhoyansk Range of Yakutia. It is believed that in these places the earth’s crust is “fastened” with bridges to the inside, preventing them from slipping through the mantle. Scientists are based on the fact that in these places interesting bends of mountain ranges were discovered on land and under water, arising under the influence of huge forces acting in the earth's crust and under it.

No less interesting is how the Earth revolves around the Sun. Here the force of gravity and centrifugal force act, thanks to which the planet is held in its orbit like a ball twisted on a rope. As long as these forces are balanced, we will not “fly away” into deep space or, conversely, will not fall onto the sun. As the Earth rotates, no other planet rotates. A year, for example, on Mercury lasts about 88 Earth days, and on Pluto - a quarter of a millennium (247, 83 Earth years).
