Why does the earth revolve around the sun and not the sun revolves around the earth?

To put it simply: the greater the mass of an object, the greater its gravitational pull! The farther apart two objects are, the weaker the gravitational pull between them! So a planet with a lot of mass can attract a planet with a lot of mass!

We all know that the exact explanation for the creation of the universe is that it came from a cosmic greatness.

After the big **, there are a large number of nebulae in the universe, and the dust particles in the nebula attract each other due to the action of gravity. The early universe can only be described as chaotic, and many asteroids that have just formed often collide with each other, so that we have our current earth, planets, stars, galaxies, etc. A star with a large mass attracts a star with a small mass, causing it to revolve around itself.

Each planet has an initial velocity, for example, if there is a planet passing by the sun now, if it does not collide with the sun head-on, if it is fast enough, it can escape the solar system, and if it is slow enough, it will fall into the solar system, or it can be like the earth and it is not fast or slow and just happens to become a planet in the solar system.

Newton. The discovery of the phenomenon of gravitational attraction, in which any object has a mutual attraction to each other, is proportional to the mass of each object and inversely proportional to the square of the distance between them, but it is only discovered and does not penetrate the nature of gravity.

Newton believed that the more massive the object, the stronger the gravitational pull, so the sun can make other celestial bodies in the solar system revolve around the sun.

It does not explain some of the celestial problems, but people realize that the law of gravitation is not perfect, and that there is a deeper reason behind the rotation of a small mass object around a large mass object.

To further describe the mysteries of space and gravity in the universe, Albert Einstein.

The theory of general relativity, which later became famous, was proposed.

Not only solved Mercury.

perihelion perturbation problem, and a deeper understanding of gravity.

Einstein believed that the universe can be depressed by massive celestial bodies, and it is precisely because the absolute advantage of the sun has sunken the space of the solar system, so that the earth and other celestial bodies revolve around the sun, and in the same way, because the mass of the earth bends the space around the earth, artificial satellites and the moon can revolve around the earth.

Revolution is the centrifugal force of the sun's gravitational pull that causes the earth to revolve around the sun.

and the gravitational balance of the sun, so that the earth does not fall on the sun and burn up. The rotation of the Earth due to the gravitational field of the Sun and its rotation.

It also has its own laws.

Because the gravitational pull of the earth is very small, and the gravitational pull of the sun is very large, the earth is bound by the sun, so it is the earth that revolves around the sun and not the sun revolves around the earth.

I think the main reason is that they exist in different spaces, and the result of different functions they have.

Because the sun is immobile, it is impossible to revolve around the earth, which rotates in addition to its own rotation.

It is the earth that revolves around the sun, and the movement of the earth around the sun is called the revolution of the earth. Because the earth circles the sun along with other celestial bodies in the solar system, the sun is their common central celestial body, so it is called "revolution". The Earth's rotation is counterclockwise, which is the same as the rotation direction.

The revolution of the earth is a periodic circular motion, therefore, the speed of the earth includes two aspects: angular velocity and linear velocity. If we use the sidereal year as the period of the Earth's revolution, then the average angular velocity of the Earth's revolution is 360° per year, that is, the Earth's orbit is 360° per day, which is about 59 8 per day.

It is caused by the gravitational pull between the earth and the sun. Because the mass of the sun is very large, and the sun is an energy radiation, it does not surround the earth.

The earth revolves around the sun because the sun has a gravitational pull, so the earth revolves around the sun, and the gravitational pull of the sun is greater than that of the earth.

Because of gravity, the gravitational pull of the sun is greater than that of the earth, so the earth must revolve around the sun.

It is the earth that revolves around the sun.

The earth revolution around the sun is the rotation of the earth around the sun. Just as the rotation of the earth has its own unique regularity, the rotation of the earth is caused by the gravitational field of the sun as well as the action of rotation. The rotation of the earth also has its own laws.

The rotation and revolution of the earth are simultaneous, and on the celestial sphere, the rotation is represented by the celestial axis and the celestial equator, and the revolution is represented by the yellow axis and the ecliptic. The celestial equator is on one plane and the ecliptic is on the other, and the plane where these two concentric circles are located forms an angle of 23°26, which is called the yellow-red angle. <>

Anniversary Movement of the Sun:

1. The solar annual parallax ellipse is the ecliptic, which reflects the position of the earth's orbital plane on the celestial sphere, and the vernal equinox and autumnal equinox indicate the position of the intersection line of the earth's orbital plane and the equatorial plane on the celestial sphere.

2. The position of the Sun on the ecliptic reflects the position of the Earth in its orbit. For example, if the Sun is at the vernal equinox, the Earth is at the autumnal equinox.

3. The apparent motion of the sun on the ecliptic reflects the direction of the earth's revolution.

4. The period of the annual apparent motion of the sun reflects the cycle (years) of the earth's revolution.

5. The angle of the sun's annual apparent motion reflects the angular velocity of the earth's revolution.
