Does the Earth revolve around the Sun? Does the Earth revolve around the Sun?

The planets revolve around the stars, and the sun is the star! The Earth is a planet.

It all starts with the formation of the solar system, which originated from the primordial cosmic nebula. The particles of various substances attract each other due to the gravitational pull, forming clumps, and the small clumps form large clumps.

The clumps often collide with each other, some fall apart, some form larger clumps, and so on, the largest clump becomes the sun, which has a great attraction, and thus has an orbit around it, and the smaller clumps become planets and moons that revolve around the orbit, and because the earth is a planet, bound by the sun's gravity, there is a centripetal force that moves in an approximate circle, so the earth revolves around the sun.

Yes, the planets revolve around the stars, and the sun is the star! The Earth is a planet. The stars we see at night are all stars.

From the point of view of relative motion, it can also be said that the sun revolves around the earth, and the key is who is the stationary reference.

But in the Milky Way, at least in the context of the solar system, the Earth and other planets revolve around the star of the Sun.

Sister, of course the earth revolves around the sun.

Are you an earthling? Or should you be asked: Are you in the solar system? If you say that you are not in the solar system, then the earth is not sparing the sun.

Nonsense... Then the sun revolves around the earth.

Yes. It's common sense.

Do you revolve around me?

It's a child's problem, right?,So please don't say that from the big brother above (nonsense...) Child. This has an impact on the child!!

The rotation of the Earth around the Sun is only a façade.

Not only the Earth, but also other celestial bodies in the solar system. In the solar system, the sun is the absolute boss and is in the core leadership position, all the celestial bodies form a whole around the sun, revolving around the Milky Way together, in fact, all the celestial bodies in the universe, their motion is around a certain gravitational center to revolve.

The celestial bodies in the solar system naturally revolve around a certain gravitational center, which is different from what we usually think of as the movement of celestial bodies in the solar system around the sun, and the rotation of the earth around the sun as we know it is just a simplified pattern, and the reason why we think so is because the mass of the sun occupies most of the mass of the solar system, making the mass center of the entire solar system very close to the sun.

In this way, when the planets in the solar system rotate around the center of gravity, they look like they are revolving around the sun, and if the proportion of the sun's mass is reduced by one notch, the center of gravity of the solar system, that is, the center of mass, will change, and the orbits of the planets, including the earth, will change, and they may not revolve around the sun.

Solar System:

The solar system is a special galaxy, and its special is not only the civilized planet of the earth, but also its mass that occupies the mass of the solar system, so that the center of mass of the solar system is the core of the sun, and the celestial bodies in the solar system can only move around the sun.

However, there are countless galaxies in the universe, and some galaxies are very different from the solar system, and the mass of stars is not as large as that of the sun, so the celestial bodies in the galaxy are not completely moving around the stars, but around a gravitational center, that is, the center of mass.

The gravitational pull of the sun causes the earth to have to revolve around the sun.

The rotation of the earth follows the laws of the earth's orbit, the earth's orbital plane, the yellow-red angle, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution. The time it takes for the earth to revolve around the stool is one year. There are two distinct cycles in the process of the Earth's revolution, which are the return year and the sidereal year, and the time of the return year is not the same as the sidereal year.

The one-year time difference between the two is called precession.

Since the Earth's orbit is elliptical, the distance between the Sun and the Earth changes as the Earth revolves around the Sun. The closest point in the Earth's orbit to the Sun, that is, the end of the long axis of the elliptical orbit closer to the Sun, is called perihelion. In modern times, the date of the Earth's perihelion is about the beginning of the first month of each year.

At this time, the Earth is about 147,100,000 kilometers from the Sun, commonly known as the solar distance.

The farthest point in the Earth's orbit from the Sun, the far end of the long axis of the elliptical orbit from the Sun, is called the aphelion. In modern times, the date of the aphelion of the Earth is about the beginning of July every year. At this time, the Earth is about 152,100,000 kilometers from the Sun, commonly known as aphelion.

The position of the solar system:

The Sun is just a very ordinary star in the universe, but it is the central object of the solar system. In the solar system, eight planets, including our Earth, some dwarf planets, comets and countless other small bodies of the solar system orbit the sun under the strong gravitational pull of the sun.

The territory of the solar system is huge, taking Pluto as an example, its orbit is nearly 40 astronomical units away from the sun, that is, 6 billion kilometers away, and in fact, the scope of the solar system is dozens of times that of this. But such a huge family of solar systems is just a very ordinary drop in the ocean in the Milky Way.

The Milky Way galaxy has at least 100 billion or more stars, about 100,000 light-years in diameter. The Sun is located on the spiral arm of Orion north of the galactic plane, about 30,000 light-years from the center of the Milky Way and about 26 light-years north of the galactic plane, and it rotates at a speed of 250 kilometers per second around the galactic center on the one hand, and at a speed of kilometers per second relative to the surrounding stars in the direction of Vega.

Why does the earth revolve around the sun is as follows:

The gravitational pull of the sun causes the earth to revolve around the sun, and the centrifugal force of the revolution is balanced with the gravitational pull of the sun so that the earth does not fall on the sun and burn up. Due to the effect of the sun's gravitational field and rotation, the rotation of the earth also has its own laws. The rotation of the earth follows the laws of the earth's orbit, the earth's orbital plane, the yellow-red angle, the period of the earth's revolution, the speed of the earth's revolution and the brother-boy effect of the earth's revolution.

The time it takes for the earth to revolve is one year. There are two distinct cycles in the process of the Earth's revolution, namely the return year and the sidereal year, and the time of the return year is different from the constant star year. The one-year time difference between the two is called precession.

Since the Earth's orbit is elliptical, the distance between the Earth changes as the Earth revolves around the Sun.

The closest point in the Earth's orbit to the Sun, the closer end of the long axis of the circular orbit to the Sun, is called perihelion. In modern times, the date of the Earth's perihelion is around the beginning of January every year. At this time, the Earth is about 147,100,000 kilometers from the Sun, which is often called the farthest point from the Sun in the Earth's orbit, that is, the end of the long axis of the circular orbit farther from the Sun is called the aphelion.

In modern times, the date of the aphelion of the Earth is about the beginning of July every year. At this time, the Earth is about 152,100,000 kilometers from the Sun, which is often referred to as aphelion.

The law of gravitation was first proposed by Newton in his book The Mathematical Principles of Natural Philosophy, published in 1687. Newton used the law of gravitation to explain not only the laws of planetary motion, but also pointed out that the moons of Jupiter and Saturn orbit the planets in the same way.

He believed that the moon was subject to the gravitational pull of the sun in addition to the gravitational pull of the earth, thus explaining the two uniform differences, business trips, etc., which had long been discovered in the movement of the moon; In addition, he explained the orbits of comets and the tidal phenomena on Earth. According to the law of gravitation, Neptune was successfully predicted and discovered.

After the law of gravitation appeared, the study of the motion of celestial bodies was formally based on the theory of mechanics, thus creating celestial mechanics. To put it simply, the more massive the object is, the greater the gravitational force, which is directly proportional to the mass of both objects and inversely proportional to the square of the distance between the two objects.

The reason why the earth revolves around the sun is mainly due to the gravitational pull of the sun. According to Newton's law of universal gravitation, the gravitational pull exerted by the sun on the earth is strong, and this gravitational pull is the attraction of the earth towards the sun, thus keeping the earth in constant motion around the sun. In addition, the motion of the earth around the sun can also be explained by the law of inertia, as the earth is subject to its inertia and still revolves around the sun in a particular orbit.

In the early stage of the formation of the solar system, the flow and collision of materials during the formation also formed the original fracture rock cause of the rotation of the nuclear celestial body around the sun. This movement not only influences the planet's seasonal changes, but also gives us the planet its unique place of life.

According to the laws of the universe, the sun is attractive so that the earth can revolve around the sun.

Because the sun itself is a huge gravitational pull and very large, I. The earth cannot get rid of the sun. Just like the Moon can't get rid of the Earth.
