Why does the earth revolve around the sun?

The first is that the sun is the core celestial body of the solar system, and the mass accounts for the total, so the gravitational force, which is the main force between the celestial bodies, is the strongest in the solar system, and the earth has the strongest interaction with it, and the form of motion is determined by the sun-earth force.

The second is why it "rotates" around the sun, which requires an analysis of how this force works. Gravitational force is to pull the earth closer to the center of the sun, but the earth has not been pulled into the belly of the sun for hundreds of millions of years, because there is another force that counters it: centrifugal force.

This force is only produced by the earth revolving around the sun, like the feeling of a chain ball being thrown out after it has been spun up. This force balances with gravity, so that the Earth forms a stable form of motion around the Sun.

Because there's gravity!

Because of gravity, more transparent is because the mass of the Sun is greater than that of the Earth (just as the Moon revolves around the Earth), and the greater the mass, the greater its gravitational pull.

Because the earth has a center of gravity. It itself rotates around its center of gravity. Because the Earth is not really a star, it will form an orbit in the vast universe. The sun is the center of the earth'shaft'Because of the attraction of the earth itself. Drove his rotation.

The Sun and the Earth were born during the formation of the solar system, when the center condensed a large amount of material to form the Sun, and the small mass centers on its periphery became planets, and the planets revolved around the Sun due to gravity.

The earth revolves around the sun because there is a gravitational force between the earth and the sun, and this gravitational force is known as gravitational force.

According to the law of gravitation, any two objects attract each other in a way that is proportional in size to their mass and inversely proportional to the square of the distance between them. Because the mass of the Sun is much greater than that of the Earth, the Earth receives a strong gravitational pull from the Sun, and the Earth orbits around the Sun, becoming what is said to be an revolution.

The Earth not only revolves around the Sun, but also rotates. The reason for the rotation of the earth is that the earth is constantly rotating, so all living things and matter on the earth are subjected to centrifugal force and are thrown out of part of it. This makes the shape of the Earth oblate spherical.

At the same time, the rotation of the Earth has also formed natural phenomena such as the alternation of day and night and the change of seasons.

Gravitation is one of the important forces that describe the interaction between objects, pointing out that there is a force between any two objects that attracts each other, which is called gravitational force. According to the law of gravitation, the gravitational force between two objects is directly proportional to their mass and inversely proportional to the square of the distance between them.

Applications of gravitation:

1. Interstellar navigation.

The law of gravitation is used to calculate the gravitational potential field in interstellar navigation, helping navigators calculate the best route and avoid trail search sock collisions. The law of gravitation is used to calculate the orbits of low-Earth orbit and deep-space exploration vehicles and how they reach the target planet or moon.

2. Solar energy.

The light and heat emitted by the sun are transmitted through photons, but the law of gravity also provides an important force for the planets and moons in the solar system, causing them to move in orbit, which provides us with the potential of solar energy, so that human beings can enjoy the sun's rays continuously.

3. Movement on Earth.

The law of gravitation is used to calculate the gravitational force between different locations on Earth, including celestial motion and orbits of artificial satellites. The law of gravitation can also be used to explain the formation of planets and moons. By considering the process of matter aggregation and gravitational concentration, physicists can simulate the entire planet-forming process.
