Since school, we know that all planets have orbits in the same plane, called the plane of the ecliptic, and also that these orbits are circular, as well as satellites that revolve around the planets. All of this eventually revolves around the sun in the same direction. Probably, the excellent students even remembered that the directions in which the planets revolve their axis are exactly the same as the direction in which they revolve around the Sun. However, all this information is actually not very accurate and is accepted with the clause "almost".
The orbits of the planets, it turns out, lie almost in the same plane. These orbits are almost circular, or rather even elliptical. In addition, the direction of rotation of many planets around their axis is similar to the direction in which they move around the sun. There are also exceptions, namely Uranus and Venus. Moreover, not all satellites revolve around planets in the same direction in which planets revolve around the Sun.
As it turned out, it is not so easy to create a unified theory that would describe all these facts with an equal degree of reliability. The question of how a system similar to our solar system could have appeared has been the main problem of cosmogony for a very long time. Most likely, the common plane of the ecliptic is associated with the fact that the "building material" for the planets and the Sun was once a single material, and it probably rotated around its axis. Then, for some reason, this material was divided in half into equal parts, retaining the direction of its original rotation. Most of this material turned into a ball of the Sun, and the smaller part became a disk around it. It was from this disk that the planets appeared, which is the answer to the question why the planets of rotation of the planets around the Sun almost coincide.
