If the earth is used as a reference, the sun revolves around the earth, and the sun is moving, including the planets around the earth, which can be seen as moving around the earth. Just as we stand on the earth and see the sun rise and set in the west, we can see the sun moving with the earth as a reference. That is to say:
The sun revolves around the earth, and Kepler's law holds! In real life, the Earth revolves around the sun, which starts with the formation of the solar system: the solar system 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. And we often say that the earth revolves around the sun because we take the sun as a reference, and the earth revolves around the sun.

In Ptolemy's time, geocentrism prevailed, and everything in the universe revolved around the earth. After the advent of Copernicus' heliocentrism and until the establishment of modern cosmology, the Earth was nothing more than a speck of dust in the universe, circling endlessly around a small yellow dwarf.
But in any case, when the earth is used as a frame of reference, everything in the universe (including the sun) still revolves around the earth. Astronomers came up with a model called the celestial sphere. It is a large sphere with the Earth as its center and a radius of 10 parsecs (light years).
When we study the motion and luminosity of various celestial bodies such as stars, planets, the sun, the moon, and galaxies, as well as the sunrise, sunset, and seasonal changes, we all "put" these celestial bodies to this big sphere. At this time, the sun undoubtedly revolves around the earth.
Different perspectives, different angles of observation and research, different content and methods of research, different phenomena and interpretations are also seen.

No, it is the earth that revolves around the sun, which is also called revolution.
The Earth revolves around the Sun in a certain orbit. Just as the rotation of the earth has its own unique regularity, the rotation of the earth and its rotation caused by the excitation field of the sun also have their own regularity. The rotation of the earth follows the laws of the earth's orbit, the surface of the earth's orbit, the yellow and red angles, the period of the earth's rotation, the speed of the earth's rotation and the effect of the earth's rotation.
The time it takes for the Earth to revolve around the Sun is the Earth's orbital period. In general, the Earth's orbital cycle is a "year". Since the period of the annual apparent motion of the Sun is the same as the period of the Earth's rotation, the period of the Earth's rotation can be measured by the annual apparent motion of the Sun.
Observers on Earth observe that the time interval between successive points of the Sun passing through the ecliptic is a "year". The length of the "year" is different due to the different reference points. The commonly used periodic units are sidereal years, regression years, and nearest point years.

The earth revolves around the sun. Due to the gravitational field and rotation of the sun, the earth rotates according to a certain orbit of the sun, which is called the earth's revolution phenomenon. The Earth's speed is about 30 kilometers per second, and its shape is an ellipse that is close to a perfect circle.
The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.
1 The sun does not rotate, and while the earth revolves around the sun (the earth rotates), the earth itself rotates (the earth rotates).
2 The earth revolves around the sun. 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, and the sun is their common central celestial body, it is called "revolution".
The Earth's rotation is counterclockwise, which is the same as the direction of rotation.
3 The revolution of the earth is a periodic circumferential movement, therefore, the speed of the earth includes two aspects: angular velocity and linear velocity. If we use the constant-friendly star year as the Earth's orbital period, 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.
4. The Earth rotates from west to east around its axis of rotation, rotating counterclockwise from the North Pole and clockwise from the South Pole. The Earth's axis of rotation is angled to the ecliptic plane, perpendicular to the equatorial plane.
The Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation in degrees and a linear velocity of 465 meters at the Earth's equator. It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years.

The earth revolves around the sun.
In the long history of Songbi, mankind has continued to explore the field of astronomy, and one of the important achievements is the study of planetary motion. After years of observation and analysis, in the 16th century, Copernicus proposed the theory that the earth revolves around the sun, replacing the ancient astronomical view, and this theory is still widely recognized and applied today.
The movement of the earth around the sun is periodic and regular. The sun is the center of our planet, and the planets revolve around the sun, of which the earth is the most important. The Earth orbits once a year, which takes 365 days, so the formation of a year has four seasons and a series of resonances and influences with the trajectories of other planets.
In the course of this movement, the shape of the Earth's orbit is elliptical, so the sunshine and temperature of the hand will change in different seasons, which is one of the main reasons for the change of seasons. In addition, the rotation of the earth is also due to the gravitational pull of the sun, which rotates once every 24 hours, forming a day and night cycle and different climates and ecological environments in different regions of the earth.
In short, the theory that the earth revolves around the sun is an important achievement in the field of modern astronomy, which reveals the regularity and periodicity of planetary motion, and also provides an important scientific basis for us to better understand the universe and the ecological environment of the protected wild ball.
The planets revolve around the stars, and the sun is the star! The Earth is a planet. >>>More
First, the earth revolves around the sun, the sun revolves around the Milky Way, and the earth revolves around the sun, in fact, this principle depends on the mass of the body, the greater the mass, the greater the gravitational force, and the massive celestial body distorts the natural formation of space, forming a gravitational field. The reason for the rotation of the celestial bodies in the solar system is that the mass of the sun is the largest in the solar system, and its gravitational field radiates the entire solar system, and it revolves around it by its gravitational force in its gravitational field. <> >>>More
In fact, strictly speaking, the Earth does not revolve around the Sun, but around the center of mass of the system that the Earth and the Sun make up (if the influence of other celestial bodies is not taken into account). This is because the effect of gravity is concentrated in this point, which means that the earth seems to be attracted to this one point. After studying high school physics, I know that in this case, as long as the initial velocity is not towards this center of mass (the earth is obviously not moving towards this center, the lucky one) will make a uniform circular or elliptical motion, in fact, the real circular motion does not exist, because there is resistance, its speed will continue to decrease, of course, this decrease is very small on the earth, otherwise we would have been baked. >>>More
The celestial systems involved in nursery rhymes are: the solar system; Earth-Moon system.
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
