rotation of planets

rotation of planets – The sun revolves clockwise around the center of the galaxy, but the planets in the solar system rotate counterclockwise around the sun. Why is this? The fact that the planets (if we look from above the North Pole) orbit the Sun in a counterclockwise direction is due to the way the solar system originated. The sun was born from a cloud of gas and dust called the “solar nebula” and its remnants made planets. As the cloud collapsed, it began to spin around. (The collapse of an object by gravity is called “collapse”). (If seen from above). Molecular clouds are the birthplace of stars. Although the axis of rotation of a large molecular cloud can almost be roughly the same as that of a galaxy, regional perturbations within small parts of the cloud can affect the direction of rotation of a baby’s stars. [It was by chance that this did not happen]. Based on the observations of astronomers, there is no preferred (superiority) direction for the rotation of the material they are in. In addition, there is no superior orientation for the rotation axis of the stars; The axis of rotation of a star after its birth can be the same as the plane of rotation of the galaxy, or perpendicular to it or any direction between the two. This can also be said: the direction of the axes of rotation (poles) of stars across the galaxy seems to be in different directions.

PIA hires But let’s take a look back. When we say that the sun was made of a cloud of gas and dust, we are in fact referring to a “cloud” which is itself a fragment or sub-region of a much larger structure called a “giant molecular cloud”. Giant molecular clouds do not form just one star, but many stars, hundreds of thousands of stars. And in general, the angular momentum and axis of rotation of these giant molecular clouds are either in the direction of the galaxy’s rotation (upward rotation) or in the opposite direction of the galaxy’s rotation (backward rotation). But inside these large clouds, there is other news. Factors such as perturbations due to supernova shock waves and magnetic effects that occur when parts of the cloud close to form stars also affect the angular momentum and final orientation of the rotation of the baby’s stars. These interactions can be very complex, and this is probably why there is no superior direction or direction for the stars to rotate. The star is more affected by local conditions than the rotation of the Milky Way; Or even the larger cloud from which the star was born.

The sun revolves clockwise around the center of the galaxy, but the planets of the solar system rotate counterclockwise around the sun. Why is that?
The fact that the planets (if we look from above the North Pole) orbit the Sun in a counterclockwise direction is due to the way the solar system originated. The sun was born from a cloud of gas and dust called the “solar nebula” and its remnants made planets. The cloud began to spin around at the same time as Mirumbid. It was by chance that the rotation of this cloud took a counterclockwise direction (if seen from above).
The solar system could have emerged from the cloud from the beginning with a clockwise rotation [luckily it did not]. Based on the observations of astronomers, there is no preferred (superiority) direction for the rotation of the material they contain.

Situational circulation – rotation of planets
To investigate the reason for this kind of planetary rotation, we have to travel to 4,600,000,000 years ago. When the planets did not exist as we see them. At that time, the dust particles surrounded and circled the sun; As they stuck together to form the planets, they created a new rotational force that caused the planets to rotate. Because planets, even if they are several thousand kilometers in diameter, are made of small particles.

The positional rotational speed in different parts of the planet – rotation of planets
In this article, we have calculated the linear velocity at the equator of the planets to measure the rotational speed of the planets. Because the linear velocities of planetary points vary at different latitudes; Because the linear velocity in a circular motion depends on the distance from the path to the central axis; The same thing as the radius of the orbit. Given this time and the fact that Mercury is 4,879 km in diameter, its rotational speed is 3.03 meters per second. That is, every point in the equator of Mercury moves at a speed of 3.03 meters per second. For a better idea, it passes through one residential unit every second. If the Earth had this velocity, the length of the days would be 153 days and 10 hours. This is the length of the equator. If the periodicity of the planet is up-to-date, we divide the length of the equator by the period of the up-to-date orbit. Speed ​​per day / km (read: km / day) is now obtained. Now to convert it to hours, we have to divide the number obtained by 23.934525 hours. Most likely you have not encountered this number before. This number is the exact duration of the Earth’s rotation; Which is equivalent to 23 hours, 56 minutes, 4 seconds, and 0.09 seconds. Now we have converted the speed of the day/kilometer to hours/kilometers (called: kilometers per hour), the task becomes simple. Divide the resulting number by 60 twice, first converting it to minutes/kilometers and then to seconds/kilometers.

Jupiter
The planet, which is the largest planet after the Sun (in the solar system), has the shortest period of orbital rotation between the planets. “Jupiter’s position rotation time at the equator is shorter than its higher and lower regions. So that in the system ||, the duration of the rotation is 9 hours and 55 minutes and 40,632 seconds, and the number written in the “Duration” section is related to the equator. “Source of content in orange: the book” Earth from space »Author: Engineer Ahmad Dalaki, from the Institute of Geography and Cartography of Geology. Of course, the solid part of Jupiter, the nucleus, moves between the two in an average time. Because all parts of a solid sphere are connected to each other.
