The Sun revolves around the center of the Milky Way? Why does the Milky Way rotate too?

Because the planets of the solar system are too close to the sun, the gravitational pull of the sun on the planets in the system is greater than that of the galactic center, so they will not be attracted to the center of the galactic galaxy; According to the current theory, the universe is constantly expanding, so there is no center, so the Milky Way does not orbit, and the autobiography is because it has a moving speed and is subject to the gravitational pull of other celestial bodies, which needs to keep moving in order not to be attracted and swallowed.

At present, no one can prove that the sun revolves around the center of the Milky Way or that the Milky Way is also rotating, so this question is a bit of a problem, and generally no one has been to the solar system or the Milky Way other than the field, so this question belongs to the topic of singularity theory, not the topic of relativity.

The Sun revolves both around the center of the Milky Way and from west to east on its axis.

The Sun revolves around the center of the Milky Way, and the period of its orbit around the center of the Milky Way is about one year.

There may be a huge black hole at the center of the Milky Way, but it is surrounded by stars that look like a "silver disk". These stars all revolve around the "silver core". Unlike the Earth's orbit, these stars get closer to the "silver nucleus" with each orbit.

The Sun, like other celestial bodies, rotates from west to east on its axisHowever, observations and studies have shown that the rotation speed is different at different latitude grinds on the surface of the sun.

At the equator, it takes days for the sun to rotate one week, at latitude 40, and at the poles, it takes about 35 days to rotate for one round. This way of rotation is calledPoor Rotation.

The theory of the differential rotation of the sun was only started in the sixties, because the understanding of the large-scale circulation in the troposphere of the sun has made great progress, so the theory of the differential rotation of the sun was put forward on the basis of the turbulence theoryThe basic idea is that the small-scale convection of rice grain organization and super-rice grain organization can be regarded as a kind of viscous effect, and due to the interaction of non-axisymmetric global-scale convection and rotation, the angular momentum is transferred to the equator, resulting in the poor rotation of the sun.

In 1610, when Galileo Galilei studied sunspots, he found that some of the regular movements of sunspots were the result of the sun's rotation.

The existence of the rotation of the Sun can be confirmed by the movement of sunspots and other active objects on the solar surface, such as sunspots, dark bars and spectral spots, or from the Doppler effect of the spectral lines on the eastern and western edges of the Sun.

The direction of rotation of the sun is the same as that of the earth. At the equator of the sun, the rotation is the fastest, and the higher the latitude, the slower the rotation, which indicates that the sun has a poor rotation.

In the solar system, the Earth and all the planets revolve around the Sun while rotating. Is the sun, the center of the solar system, also rotating and orbiting? The ancients did not know about this question.

It wasn't until Galileo Galilei invented the telescope in 1609 that he proved that the sun was constantly rotating.

The direction of rotation of the Sun is the same as that of the Earth, rotating from west to east, so sunspots move from east to west on the surface of the Sun as seen from the Earth. Since the Sun is a gaseous sphere, its surface rotates at different latitudes. The equatorial region is the fastest, taking only 25 days to complete one revolution.

As the latitude increases, the rotation speed becomes slower and slower. At 80 degrees latitude, it takes 35 days to make a turn. Compared with the nine planets, only Mercury and Venus have a longer rotation period than the Sun, and the other planets (including Earth) do not have a longer rotation period than the Sun.

Recent studies have found that the rotation period of different levels of the sun's interior is also different.

The Sun is not only rotating, but it is also leading the entire solar system, orbiting the center of the Milky Way at a speed of 250 kilometers per second. We call this movement "the orbital motion of the sun".It takes about 100 million years for the Sun to revolve around once.

While the Sun revolves around the center of the Milky Way, it is also speeding towards the constellation Hercules, at a speed of 20 kilometers per second.

The sun is moving at such a fast speed, why can't we see it? This is because all the members of the solar system follow the motion of the sun, and each member carries the speed of the sun's motion. Therefore, each member does not feel the same part of the movement as the sun, but only the relative movement between himself and the sun.

It's like people don't feel like they're following the Earth's rotation.

Summary. Hello, because the gravitational attraction of all the celestial bodies in the Milky Way has a gravitational center, which is the common center of mass of the entire Milky Way, and the stars in the Milky Way will revolve around this center, and this center is what we call the center of the Milky Way.

Hello, because there is a gravitational center of gravity between the gravitational force of all the celestial bodies in the Milky Way, which is the common center of mass of the entire Milky Way, and the constant star in the Milky Way will revolve around this center, and this center is what we call the center of the Milky Way.

Every star in the Milky Way, as well as other matter (mainly dark matter), contributes a portion of the gravitational pull to the Milky Way so that the galaxy can remain a whole paraomen. Since the center of gravity of all objects in the Milky Way is in the galactic center, all celestial bodies, including stars, revolve directly or indirectly around the galactic center.

The reason why the Milky Way can maintain a state of gravitational equilibrium is because of the gravitational collection formed by the balance of Sagittarius A, galactic mass, and dark matter, so that hundreds of billions of stars revolve around the center of the Milky Way.

Who has the greater gravitational pull of the sun or the earth, and is the gravitational pull of the sun and the earth opposite? So you won't suck a piece?

In addition to the mass of the object itself, there is also a distance factor that affects the gravitational force of Wanwei. The gravitational force is directly proportional to the mass of the object and inversely proportional to the square of the distance. Although the mass of the Sun is greater than that of the Earth, the distance between you and the Earth's center of gravity is much smaller than the distance between you and the Sun's center of gravity, so the gravitational pull of the objects on the Earth's hunger is greater than the gravitational pull of the Sun's fingers.

Gravitational force is directly proportional to the mass of the object, and the mass of the Sun is much greater than that of the Earth, and the gravitational force is much greater than that of the Earth.

The earth will not be sucked by the sun, it's like you use a rope to pull a crack and throw an iron ball around it, your hand is equivalent to the sun, the iron ball is equivalent to the earth, the pull of the hand to the ball is equivalent to the gravitational force between the sun and the earth, the ball obviously will not be pulled away by your hand, just do a circular motion around your hand, Xunzhi This is the characteristic of circular motion in the physics of high school bridge Changshu, the earth has been doing circular motion around the sun, it will neither be thrown out nor sucked by the sun.

The sun calls the earth to follow as if it were his child?

It can be understood, but it can't be approached.

Modern physics (general relativity) holds that gravitational attraction arises as a result of the curvature of space-time. As we all know, the line segment between the two points of the imperial object is the shortest, which is the axiom of the plane several rules to let He, and this line segment is the short-range line. However, in the bent four-dimensional space-time, the short-range line is also bent.

Therefore, due to gravity, the planets move closer to the Sun along a short-range line.

Located in the Orion spiral arm of the Milky Way, the Sun takes the entire solar system counterclockwise around the center of the Milky Way (said to be a giant black hole) with an orbital period of about 100 million years.

The Sun is located on the Orion Arm, an arm of the Milky Way, at a distance of about 26,000 light-years from the center of the Milky Way. Rotate clockwise.

1.The Sun is now located in a celestial area called the "Local Bubble" on the inside of the Orion Arm (i.e., on the side of the Silver Heart).

2.The Sun belongs to a group called the Pleiades, which orbit around the center of mass of the open cluster at the edge of the cluster.

3.The Sun follows the Pleiades around the center of the Milky Way with a period of 10 8 years.

4.The angle of rotation of the sun and the axis of rotation of the Milky Way is 62°36, that is, it reclines and revolves around the Milky Way, similar to the way the earth revolves around the sun.

Answer: The sun revolves around the Milky Way in a strange way, as if it is drawing circles on one side and moving around the center of the Milky Way at the same time.

<> yellow dot is the location of the solar system. The Dark Matter region is not dark matter. It's just that humans can't see through the massive amount of dust in the silver core right now.

As the Earth rotates, it also revolves around the Sun. The rotation of the earth divides the day on the earth into day and night, and the revolution around the sun forms the four seasons of spring, summer, autumn and winter of the year. The Sun also revolves around the center of the Milky Way in the Milky Way, and it takes more than 200 million years to make one revolution.

So will the rotation of the sun around the center of the Milky Way also produce "seasons" like the earth's revolution around the sun, similar to spring, summer, autumn and winter?

To understand this question, we must first understand what kind of effect the sun has on the earth. The earth revolves around the sun, and the sun exerts the centripetal force required for the earth to turn. At the same time, the light emitted by the sun can also significantly affect the earth, not only causing day and night on the earth, but also spring, summer, autumn and winter on the earth due to the tilt of the earth's axis.

The sun shines directly on the Tropic of Capricorn at noon on the winter solstice, and the intensity of the sun at noon on the Tropic of Cancer is only about 68% of that at the Tropic of Capricorn. This disparity is obvious, and it is because of this that the four seasons are formed. Gravity and light are the two major effects of the sun on the earth.

If you look at the rotation of the Sun around the Milky Way, the objects near the center of the Milky Way provide the gravitational pull for the Sun to revolve around the Milky Way, much like the Earth orbiting the Sun. Do celestial bodies near the center of the Milky Way provide light to the solar system? No.

This is markedly different from the Earth's rotation around the Sun.

Looking up at the starry sky at night, you can see some of the stars shining. Those stars you see include several planets in the solar system, like Venus, Saturn, Mars, etc., and although they don't emit light, they also look very bright due to their proximity to Earth. There are also stars that are relatively close to Earth and are also relatively large, such as Sirius, which are only light-years away from Earth.

Light-years may seem large, but they are negligible compared to the Milky Way's radius of 100,000 light-years. Proxima Centauri, the closest star to Earth, is so faint that it is not visible to the naked eye, and its brightness is increased by 100 times to be barely seen with the naked eye. The celestial bodies that people can see with the naked eye at night, with the exception of a very few celestial bodies such as Andromeda, are distributed in a small area around the solar system.

As the Sun revolves around the center of the Milky Way, the change in illumination is completely negligible. In this case, there will be no seasonal changes like spring, summer, autumn and winter.

Strictly speaking, there is no periodicity in the rotation of the Sun around the center of the Milky Way. It takes more than 200 million years for the Sun to complete one revolution, and many massive stars have a lifespan of only a few million years, and even for the Sun, a star with a lifespan of 10 billion years, more than 200 million years will change its mass very much. After the sun has completed its rotation, it has long been a matter of time, and the orbit of the sun will obviously not be a closed ellipse.

Collisions with other galaxies are possible. In the process of constant motion, the solar system will one day meet with other galaxies and usher in a catastrophe.

If the sun revolves around the center of the Milky Way, it will actually cause the world, which is our entire day, to be dark. There will be no light.

The Sun is ostensibly motionless, but the reality is that the Sun is revolving around the Milky Way**. So, if the sun revolves around the center of the Milky Way, there will be no consequences.

Strictly speaking. The Sun moves in a spiral orbit around the center of the Milky Way, not a closed ring. However, the Sun's motion is affected by the gravitational pull of many surrounding celestial bodies, and it is very slow, since the birth of the Sun, it has only circled the center of the Milky Way more than 27 times, and the Milky Way will collide with the Andromeda Galaxy, which is twice the size of the Milky Way, so the Sun will not necessarily enter the galactic center.

Even if it could enter the heart of the galaxy, it would take much more than 5 billion years, which is longer than the life span of the sun!
