The predecessor of the solar system was a dense cloud, driven by a certain force that attracted each other, and this accretion process made the density gradually larger, which accelerated the accretion process. The particles in the primordial solar nebula were initially in a chaotic state, rampage, and gradually turned the disordered state into an ordered state, on the one hand, the centripetal accretion accumulation became the sun, and on the other hand, the gas gradually developed into a flat shape.
In the process of development, the potential energy becomes kinetic energy, and finally the whole thing turns. At the beginning of the rotation, there are those who turn this way, and those who turn that way, after a certain direction prevails, they all become one direction, and this direction is the right-hand rule that is now discovered, and there may be other solar systems that are left-handed rules, but in our solar system it is the right-hand rule. The energy of the earth's rotation** is caused by the eventual transformation of material potential energy into kinetic energy, which ultimately means that the earth rotates on the one hand and rotates on the other.
If the sun stops rotating, it can be understood that the potential energy of the sun can no longer propel its rotation, and the sun is no longer the core of the solar system. According to the centripetal accretion force, the earth does not revolve around it!

The autobiography of the Sun goes back to the change in the distance between the sunspot solar storm and the Earth, which may cause fluctuations in the Earth's magnetic field, tides, etc.
But the rotation of the earth is caused by gravity as the centripetal force of the earth's revolution and has little to do with rotation.
-
Yes, it doesn't matter, from the point of view of the earth, the sun is a mass point, and there is no such property as rotation at the point.
-
As long as the sun does not disappear and the earth does not perish and is not attacked by other stars.

It's a question worth thinking about, and if you think of it, tell us, right?

The sun rotates and revolutions. The rotation of the Sun is carried by the planet Milky Way, and it is said that there is a small black hole in the center of the Milky Way, and if the stars in the Milky Way do not orbit it, they will be sucked into it. The sun also has a rotation, and its rotation is the same as that of the earth, from west to east, with a cycle of 25 days.
Any celestial body in the universe is circling the rotation and revolution of a celestial body with a large mass, the planets and stones in the great solar system are rotating around the sun, and the sun is rotating and revolving around the Milky Way, if the centripetal force generated by the speed of the celestial body cannot reduce the gravitational force of the celestial body that is larger than itself, then it will be swallowed by the massive celestial body, and the meteor we see in the sky at night is the stone swallowed by the earth. The celestial bodies in the universe are all in motion, and as long as the movement is balanced, if it stands still, it will eventually cease to exist. For example, if the moon does not revolve around the earth, it will be absorbed by the earth, and it will have crashed into the earth long ago, and it will cease to exist, because of the movement around the earth, it will adhere to equilibrium, and the centrifugal rate and gravity will cancel out!
The sun has a rotation, because the sun is just an ordinary star, he coils around the center of the Milky Way - the galactic center stops orbiting, and at the same time it also rotates all the time, just like the earth-moon system composed of the earth and the moon revolves around the sun and itself is also rotating, all the celestial bodies in the solar system, from the sun at the center, to the eight planets, to Pluto and the Kuiper belt, and then to the outer Oort cloud of the solar system, this overall solar system is coiled around the galactic center, with a speed of about 660 kilometers per second. The Milky Way is moving around the Virgo Cluster, so everything in the universe is rotating and revolving, and the ones with small masses orbit around the ones with large masses, and even black holes follow this law, so the sun also has both rotation and revolution.
Revolution, the sun is also there. The revolution of the Sun is to circle around the center of the Milky Way, and it also leads the entire solar system to circle around the center of the Milky Way at a speed of about 250 kilometers per second. As for what celestial body is at the center of the Milky Way, some scientists speculate that the center of the Milky Way is a black hole, not only the sun but also all the other stars of the Milky Way themselves, and lead their own galaxy to circle around the center of the Milky Way.

Yes, the sun also has movement, the sun also has a rotation, and the direction of rotation is the same as that of the nine planets, the sun will rotate the galactic center in the galaxy, and we often say that the earth and other planets revolve around the sun, in fact, these planets and the sun orbit each other to form a revolution.
-
Yes, the sun also has rotation and revolution, and the rotation of the sun is the same as that of other planets.
-
The Sun also has a rotation and an revolution, and the rotation of the Sun is in the same direction as that of the nine planets, and the rotation of the Sun revolves around the center of the Milky Way.
This is the gravitational force that Newton discovered.
This attraction exists between any two objects. This attraction between objects is prevalent between all things in the universe and is called gravitational force. >>>More
According to the British Daily Mail, it is difficult to imagine that the stationary Earth is constantly in rotation with an equatorial rotation linear speed of 1670 km/h. What happens once the Earth's rotation stops? Currently, British scientist Michael Stevens has posted a paragraph on YouTube revealing everything that will happen when the Earth stops spinning. >>>More
The Earth will have a hurricane 12 times larger than a Category 12 typhoon; The sea and the great river went east, rushing to the mainland at a speed of more than 400 meters per second; People and all moving objects on the surface of the earth will rush eastward at a speed 10 times faster than a Mercedes car......That would be the end of humanity! >>>More
Kill the Moon, and the Earth's rotation speed will increase significantly, which is unbearably fast.
Before discussing this topic, we must admit that the probability of such an event in the next few billion years is almost zero. >>>More
