For me personally, there are few things in the world as mysterious and interesting as the structure of the Universe, as well as where the planets came from, what happened before they appeared, and so on. I don’t understand at all how and where our world came from. It would be nice if only our planet. But imagine, if you fly forever in a straight line, how can it be that there is no end? These things I cannot comprehend. But there are slightly simpler questions to which science has already been able to find answers.

Does the earth revolve around the sun

Perhaps someone thinks that this issue has been closed for a long time. Unfortunately no. According to the largest sociological service in Russia, approximately 25% of Russians believe that it is the Sun that revolves around the Earth. Considering the unexpectedness of this result, an all-Russian survey on this topic was conducted several times over several years, and each time the figure, unfortunately, was confirmed.

But back in the 16th century in Europe, some scientists and outstanding thinkers of that time risked their lives, declaring that the center of our system is the Sun. For example, these:

• Giordano Bruno.
• Nicolaus Copernicus.
• Galileo Galilei.

Almost 500 years have passed, and you see, a quarter of Russians still live in some special reality, alas.

Star Sun and eight planets

The structure of our solar system is such that all the planets revolve around the Sun, which is the largest, or rather, relative to all other planets, simply a huge star. To understand the difference: in our solar system there are 8 planets and the star the Sun. So here it is The mass of the Sun accounts for more than 99% of the mass of the entire solar system.

Do you understand what a huge difference it is? Well, in accordance with the laws of gravity, bodies in space rotate around one another according to the principle “the lighter one rotates around the heavier one”. Distance also matters; the shorter the distance, the stronger the attraction. But the mass of the Sun is such that the distance between it and the planets of our system does not allow these planets to “fly into space.” Each in its orbit constantly revolves around the Sun. How one can think that this Sun revolves around the Earth is a big mystery to me.

For an observer located in the Northern Hemisphere, for example, in the European part of Russia, the Sun usually rises in the east and rises to the south, occupying the highest position in the sky at noon, then slopes to the west and disappears behind the horizon. This movement of the Sun is only visible and is caused by the rotation of the Earth around its axis. If you look at the Earth from above in the direction of the North Pole, it will rotate counterclockwise. At the same time, the Sun remains in place, the appearance of its movement is created due to the rotation of the Earth.

Annual rotation of the Earth

The Earth also rotates counterclockwise around the Sun: if you look at the planet from above, from the North Pole. Because the Earth's axis is tilted relative to its plane of rotation, it illuminates it unevenly as the Earth rotates around the Sun. Some areas receive more sunlight, others less. Thanks to this, the seasons change and the length of the day changes.

Spring and autumn equinox

Twice a year, on March 21 and September 23, the Sun illuminates the Northern and Southern Hemispheres equally. These moments are known as the autumn equinox. In March, autumn begins in the Northern Hemisphere, and autumn in the Southern Hemisphere. In September, on the contrary, autumn comes to the Northern Hemisphere, and spring to the Southern Hemisphere.

Summer and winter solstice

In the Northern Hemisphere, on June 22, the Sun rises highest above the horizon. The day has the longest duration, and the night on this day is the shortest. The winter solstice occurs on December 22 - the day has the shortest duration and the night has the longest. In the Southern Hemisphere, the opposite happens.

polar night

Due to the tilt of the earth's axis, the polar and subpolar regions of the Northern Hemisphere are without sunlight during the winter months - the Sun does not rise above the horizon at all. This phenomenon is known as polar night. A similar polar night exists for the circumpolar regions of the Southern Hemisphere, the difference between them is exactly six months.

What gives the Earth its rotation around the Sun

Planets cannot help but revolve around their stars - otherwise they would simply be attracted and burnt up. The uniqueness of the Earth lies in the fact that its axis tilt of 23.44° turned out to be optimal for the emergence of all the diversity of life on the planet.

It is thanks to the tilt of the axis that the seasons change, there are different climatic zones that provide the diversity of the earth's flora and fauna. Changes in the heating of the earth's surface ensure the movement of air masses, and therefore precipitation in the form of rain and snow.

The distance from the Earth to the Sun of 149,600,000 km also turned out to be optimal. A little further, and water on Earth would only be in the form of ice. Any closer and the temperature would already be too high. The very emergence of life on Earth and the diversity of its forms became possible precisely thanks to the unique coincidence of so many factors.

Man sees the Earth as flat, but it has long been established that the Earth is a ball. People agreed to call this celestial body a planet. Where did this name come from?

Ancient Greek astronomers, who observed the behavior of celestial bodies, introduced two terms with opposite meanings: planetes asteres - “stars” - celestial bodies similar to stars, moving throughout; asteres aplanis - “fixed stars” - celestial bodies that remained motionless throughout the year. In the beliefs of the Greeks, the Earth was motionless and located in the center, so they classified it as a “fixed star”. The Greeks knew Mercury, Venus, Mars, Jupiter and Saturn, visible to the naked eye, but they called them not “planets”, but “wandering”. In Ancient Rome, astronomers already called these bodies “planets”, adding to this the Sun and the Moon. The idea of ​​a seven-planet system survived until the Middle Ages. In the 16th century, Nicolaus Copernicus changed his views on the device, noticing its heliocentricity. The Earth, previously considered the center of the world, was reduced to the position of one of the planets revolving around the Sun. In 1543, Copernicus published his work entitled “On the Revolutions of the Celestial Spheres,” in which he expressed his point of view. Unfortunately, the church did not appreciate the revolutionary nature of Copernicus’s views: his sad fate is known. By the way, according to Engels, the “liberation of natural science from theology” begins its chronology precisely with the published work of Copernicus. So, Copernicus replaced the geocentric system of the world with a heliocentric one. The name “planet” has stuck with the Earth. The definition of a planet, in general, has always been ambiguous. Some astronomers argue that the planet must be quite massive, while others consider this an optional condition. If we approach the issue formally, the Earth can be safely called a planet, if only because the word “planet” itself comes from the ancient Greek planis, meaning “movable,” and modern science has no doubt about the mobility of the Earth.

“And yet, she spins!” – we have known this encyclopedic phrase, uttered by the physicist and astronomer of the past Galileo Galilei, since our school days. But why does the Earth rotate? In fact, this question is often asked by their parents as young children, and adults themselves are not averse to understanding the secrets of the Earth’s rotation.

For the first time, an Italian scientist spoke about the fact that the Earth rotates around its axis in his scientific works at the beginning of the 16th century. But there has always been a lot of controversy in the scientific community about what rotation occurs. One of the most common theories says that in the process of the earth’s rotation, other processes played a major role - those that took place in time immemorial, when only education. Clouds of cosmic dust “came together”, and thus the “embryos” of planets were formed. Then other cosmic bodies – large and smaller – were “attracted”. It is precisely collisions with large celestial ones, according to a number of scientists, that determine the constant rotation of the planets. And then, according to the theory, they continued to rotate by inertia. True, if we take this theory into account, many natural questions arise. Why are there six planets in the solar system that rotate in one direction, and another one, Venus, in the opposite direction? Why does the planet Uranus rotate in such a way that there is no change in time of day on this planet? Why can the speed of rotation of the earth change (slightly, of course, but still)? Scientists have yet to answer all these questions. It is known that the Earth tends to slow down its rotation somewhat. Every century, the time for a complete rotation around an axis increases by approximately 0.0024 seconds. Scientists attribute this to the influence of the Earth's satellite, the Moon. Well, about the planets of the solar system, we can say that the planet Venus is considered the “slowest” in terms of rotation, and Uranus is the fastest.

To the question, does the Sun revolve around the Earth or vice versa? given by the author Strip the best answer is The Earth orbits the Sun and makes a complete revolution around it in approximately 365.26 days. This period of time is the Sidereal year, which is equal to 365.26 solar days. The Earth's rotation axis is tilted 23.4° relative to its orbital plane, this causes seasonal changes on the planet's surface with a period of one Tropical year (365.24 solar days).
The Earth moves around the Sun in an elliptical orbit at a distance of about 150 million km with an average speed of 29.765 km/sec. The speed ranges from 30.27 km/sec (at perihelion) to 29.27 km/sec (at aphelion). Moving in orbit, the Earth makes a full revolution in 365.2564 average solar days (one sidereal year). From Earth, the movement of the Sun relative to the stars is about 1° per day in an easterly direction. The speed of the Earth's orbit is not constant: in July it begins to accelerate (after passing aphelion), and in January it begins to slow down again (after passing perihelion). The Sun and the entire solar system revolve around the center of the Milky Way galaxy in an almost circular orbit at a speed of about 220 km/s. In turn, the Solar System within the Milky Way moves at a speed of approximately 20 km/s towards a point (apex) located on the border of the constellations Lyra and Hercules, accelerating as the Universe expands. Carried away by the movement of the Sun, the Earth describes a helical line in space.

it seems like it was the other way around...

Answer from Glamorous[expert]
the earth revolves around the sun

Answer from I-beam[guru]
It is strange that in our enlightened age such questions arise. Based on the fact that the Earth rotates around the Sun, humanity has gone into outer space and launched ships to other planets. The Earth and the other seven planets, asteroids, comets, Pluto and other dwarf planets revolve around the Sun. The Sun, in turn, revolves around the center of our Galaxy, and it revolves around the center of the hypothetical Metagalaxy.

The Earth and Sun revolve around a common center of mass.

Answer from Yergey Kravets[active]
Degenerate or something, the sun stands still! The Earth revolves around him, it is alive, everything is alive here, even a tree, moreover, it also rotates at a certain speed, at a speed that will allow one to live on this Earth, and if the speed increases, the world will change, and such prerequisites exist. Then there will be not 24 hours in a day, and accordingly there will not be 365 days (if rounded) and all this will affect the human body, and indeed on people’s lives in general. There is still gravity on Earth, which contributes to all living things! If it weren’t for her, the world would disappear - everything would fly in space. I’m generally at least a little familiar with physics and astrophysics, if not, get acquainted, it will be useful

For a very long time, people thought that our planet was flattened and rested on 3 pillars. A person is unable to notice its rotation while standing on it. The reason for this is the size. They make a huge difference! The size of a person is too insignificant in relation to the size of the globe. Time moved forward, science progressed, and with it people’s ideas about their own planet.

What have we come to today? Is it true that and not the other way around? What other astronomical knowledge is valid in this area? First things first.

Along its axis

Today we know that it simultaneously takes part in two types of motion: the Earth rotates around the Sun and along its own imaginary axis. Yes, exactly the axles! Our planet has an imaginary line that “pierces” the surface of the earth at its two poles. Draw your axis mentally into the sky, and it will pass next to the North Star. That is why this point always seems motionless to us, and the sky seems to be rotating. We think that they are moving from east to west, but we note that it only seems to us! Such movement is visible, since it is a reflection of the planet’s real rotation - along the axis.

The daily rotation lasts exactly 24 hours. In other words, in one day the globe makes one full circle along its own axis. Each of the earth's points first passes through the illuminated side, then through the dark side. And a day later everything repeats again.

For us, it looks like a constant change of days and nights: morning - day - evening - morning... If the planet did not rotate in this way, then on the side facing the light there would be eternal day, and on the opposite side there would be eternal night. Horrible! It's good that this is not the case! In general, we figured out the daily rotation. Now let's find out how many times the Earth rotates around the Sun.

Sunny round dance

We also won’t notice this with the naked eye. However, this phenomenon can be felt. We all know very well the warm and cold seasons of the year. But what do they have in common with the movements of the planet? Yes, they have everything in common! The Earth revolves around the Sun in three hundred and sixty-five days, or one year. In addition, our globe is a participant in other movements. For example, together with the Sun and its “colleagues” the planets, the Earth moves relative to its own galaxy - the Milky Way, in turn, moving relative to its “colleagues” - other galaxies.

It is important to know that in the entire Universe nothing is stationary, everything flows and changes! Note that the movement of the celestial body we see is just a reflection of a rotating planet.

Is the theory correct?

Today, many people are trying to prove the opposite: they believe that the Earth does not revolve around the Sun, but, on the contrary, the heavenly body revolves around the globe. Some scientists talk about the joint movement of the Earth and the Sun, which occurs relative to each other. Perhaps one day the world's scientific minds will turn all the scientific ideas known today about space upside down! So, all the “i”s are dotted, and you and I learned that around the Sun (at a speed, by the way, about 30 kilometers per second), and it makes a full revolution in 365 days (or 1 year), at the same time Our planet rotates on its axis every day (24 hours).

Does the earth revolve around the sun or vice versa?

The Earth rotates around the Sun at a speed of about 30 km per second, the Sun rotates around the galactic core at a speed of about 300 km per second, like all other stars, like planets around a star.

One of my relatives, when he was drinking well, liked to say the Earth rotates, to hell with it, if only we could stand on it. As we know, there have been times in history when people were burned for making such statements. But still, the earth revolves around the sun at a speed of about 30 km/second.

Everything is always moving)

The earth moves around the sun and the sun moves around the center of the galaxy (or perhaps a larger star, I don’t remember) and the center of the galaxy rotates around something else, etc.)))

perhaps outside of our universe there are other universes that are somehow in contact...

The Earth actually revolves around the Sun. And the speed of rotation of the Earth is 30 kilometers for every second of rotation. The Sun, in turn, does not revolve around the Earth, it revolves around the galactic core, and the rotation speed is 10 times greater!

The Earth revolves around the center of our galaxy, along with the sun and people and.....

The Earth rotates around the Sun at a speed of about 30 km per second, the Sun rotates around the galactic core at a speed of about 300 km per second, like all other stars, like planets around a star.

Pavel: It all depends on what we want to know and what is simpler and more obvious for us. If we consider the motion of all the stars in the galaxy, then it is more convenient to place the origin of coordinates at the center of the galaxy, where the black hole is located. It is also more convenient for mathematical calculations. All stars orbit around this black hole, just like the planets, and the further away the stars are from the black hole, the slower their orbital speed. And the rotation of the planets around the sun is much more clear. And if you place the origin of coordinates on the Earth, then the sun will revolve around the Earth in an orbit similar to the Earth’s orbit around the sun. And what trajectories will the other planets have relative to the Earth in this case? So complex that it’s scary to even think about. But if we consider the movement of the Earth relative to the center of the galaxy, then the entire solar system moves around the center of the galaxy. And the Earth still revolves around the sun. So the Earth's trajectory will be a helical line. Question: what if we consider the movement of two stars of the same mass relative to each other? What will be the movement trajectories?

The trouble with these reference points is that there is so much confusion from them. So we can agree that it is not the wheel that spins on the car, but the car on the wheel. If we assume that the Sun revolves around the Earth, this may come into direct conflict with the point of view of the Martians, who can claim a Mars-centric model of the universe. Therefore, it would be more reasonable to come to a common denominator with them and find a Solomon solution: the Earth, Mars, and other planets of the solar system revolve around their star and fly with it around the center of galactic mass.
