How many years is the cycle of the sun? How many years has the sun existed

The Sun rotates like any other celestial body. Since the Sun is a sphere of gas, its rotation is poorly rotating, and its rotation speed varies with latitude. Regarding the rotation period of the sun, the data are not consistent, some say 25 days, some say 27 days.

Matter together with the sun, in addition to its rotation, it also revolves around the center of the galaxy with other things, which is also the rotation of the galaxy. The Sun is on one of the spiral arms of the Milky Way, about 10,000 light-years from the center of the Milky Way, at which point the Milky Way rotates at a speed of 250 km/s, which is, of course, the speed of the Sun's rotation. As for the orbital period of the sun, the current estimates are also inconsistent, some say 100 million years, some say 200 million years.

With the development of science and technology, the orbital period of the sun will gradually converge.

The Sun is a yellow dwarf star with a lifespan of roughly 10 billion years, and the Sun is currently about 100 million years old.

After about 50 to 6 billion years, the Sun's interior will be almost completely depleted, at which point the Sun will become a red giant for a short time, then gradually cool down and eventually become a white dwarf.

The solar cycle, or solar magnetic cycle, is the sunspot period.

The number and other phenomena change in the quasi-weekly stimulus period, about 11 years for a cycle. It will cause changes in the air and on the ground, and may even change the climate. This period can be observed by calculating the frequency and location of visible sunspots.

Impact: Through the important correlation between solar cycles and the Earth's global climate, a scientific study led by scientists at the National Center for Atmospheric Research in the United States has found that the peak of solar activity and the aftermath of activity can affect the Earth's reputation, leading to La Niña and El Niño-like occurrences in the Earth's Pacific tropics.

phenomenon.

The solar activation impulse cycle is about 11 years. Solar activity is the atmosphere of the sun.

The general term for all the phenomena of activity in the country, on average on an 11-year cycle. Solar radiation during periods of intense activity.

out a lot of ultraviolet light.

X-rays, particle streams and intense radio waves, such as aurora aurora on Earth, magnetic slag bursts and ionospheric disturbances, are often caused. <

The solar cycle is 11 years. Solar activity is a general term for all active phenomena in the solar atmosphere, with an average cycle of 11 years. During periods of intense activity, the sun emits large amounts of ultraviolet rays, X-rays, particle streams and intense radio waves, which often cause phenomena such as auroras, magnetic storms and ionospheric disturbances on Earth.

How many years is the cycle of solar activity: 11 years.

Solar activity is the general term for all the active phenomena in the solar atmosphere. There are mainly sunspots, light spots, spectral spots, flares, solar and coronal transient events. Caused by electromagnetic processes in the Sun's atmosphere.

The period is intense and sometimes weak, with an average cycle of 11 years. The Sun during periods of intense activity (known as the "Perturbation Sun") radiates large amounts of ultraviolet light, X-rays, particle streams, and intense radio waves, which often cause phenomena such as auroras, magnetic storms, and ionospheric disturbances on Earth.

Solar activity is a general term for a variety of different activity phenomena in local areas of the solar atmosphere. Includes:

1. Sunspots are the basic markers of solar activity.

2. Light spot: The bright tissue that appears at the edge of the sun's photosphere and extends outward to the color sphere is the spectral spot. The light spots generally surround sunspots and have a close relationship with sunspots.

3. Spectral spots: Plaques that are brighter than the surrounding patches on the sun's photosphere.

4. Solar wind: The flow of charged particles formed by the solar wind of the source ruler causes the aurora on the earth.

5. Flare: The powerful short-wave radiation emitted will cause a sharp change in the hail height of the earth's ionosphere. The impact on humanity is significant. Causing shortwave communication to be interrupted.

6. Sun: During a total solar eclipse, the sun is surrounded by a red ring with a bright red tongue of fire pulsing on it, and this tongue of fire is called a sun.

7. Corona: The corona is the outermost layer of the sun's atmosphere (its interior is the photosphere and chromosphere), with a thickness of more than several million kilometers. The coronal temperature is 1 million degrees Celsius and the particle number density is 1015 m3.

At high temperatures, atoms such as hydrogen and helium have been ionized into positively charged protons, helium nuclei, and negatively charged free electrons, etc. The corona can only be seen during a total solar eclipse and when a coronagraph is utilized.

8. Impact: Solar activity is related to volcanic eruptions, droughts, floods, diseases of the human heart and nervous system, and even traffic accidents. Therefore, the science of solar activity forecasting has also been formed.

9. Sunspots are a kind of solar activity that occurs in the photosphere of the sun, and it is the most basic and obvious phenomenon in solar activity. It is actually a huge vortex of hot gas on the surface of the sun, like a shallow disk with a concave middle, and the temperature is 1000 to 2000 times lower than the surface of the photosphere, so it looks "dark".

Analysis: The time interval for the regeneration of several important solar events, this cycle averages 22 years, and it contains two 11-year sunspot cycles.

In each cycle, the polarity of the magnetic poles of sunspots is reversed, and the variation of various other solar surface phenomena is also like sunspots, with two ** and two low tides. These solar phenomena include fluctuations in the frequency of solar rays, flares, and magnetic effects, which include aurora aurora and increased radio interference on Earth. The 11-year basic cycle of sunspots (sometimes referred to as the solar cycle) was announced by Schwabe in 1843.

Some people try to associate the solar cycle with changes in various other phenomena, such as small changes in the diameter of the sun, changes in tree rings, and even the fluctuations of the market are related to the solar cycle.

The formation of the Sun can be traced back to a star-pure tremor cloud about 4.6 billion years ago. According to the now widely accepted theory, the nebula of the cave at that time was caused by the death of some huge stars that released large amounts of matter and energy in **. These matter and energy began to clump together to form a rotating cloud of gas called the primordial solar cloud.

Gradually, the material in the primordial solar cloud began to clump together, forming a huge melting sphere of very high density and temperature. Over time, the sphere experienced high-speed rotation and gravitational collapse, gradually forming a core, which we now call the sun. The temperature and pressure inside the sun's core reach a high enough level that a nuclear fusion reaction begins to take place, converting hydrogen into helium, releasing enormous amounts of energy in the process.

The formation of the sun is part of the formation of the Earth and other planets. As the material left over from the formation of the sun gradually gathers together, they form planets and other celestial bodies. According to this theory, we can assume that the Sun and other planets formed at the same time about 4.6 billion years ago.

The Sun was formed about 100 million years ago in a cloud of collapsed hydrogen molecules. The time of the formation of the Sun is measured in two ways: the current age of the Sun in the main sequence zone, which is confirmed by a computer model of the evolution of the stars and the synthesis of the primordial nucleus, which is about 100 million years.

This is very consistent with the radioactive dating of the oldest material of the sun is 100 million years old. The Sun has reached middle age in the evolutionary phase of its main sequence, in which nuclear fusion is the fusion of hydrogen into helium at the core.

Every second, more than 4 million tons of matter are converted into energy in the core of the sun, producing neutrinos and solar radiation. At this rate, so far, the sun is approximately transformed.

The equatorial part of the Sun has the shortest rotation period, about 25 days;

about 40 degrees latitude at 27 degrees;

about 33 days at 75 degrees;

At the poles is the 37th.

Generally, the rotation period at 17 degrees latitude of the sun is called the "sidereal period of the sun's rotation", which is the day.

Since we are watching the rotation of the sun on the rotating and revolving earth, we see that the rotation period at 17 degrees of the sun is a seepage day, and the astronomical term calls this cycle the "solar rotation conjunction period".
