    The sun is not an entity, and the temperature of the center of the sun is 10,000. From the inside to the outside, they are the solar nuclear reaction zone, the solar troposphere, and the solar atmosphere. Thermonuclear reactions are constantly taking place in its central zone.

    It is mainly a huge red-hot ball of gas, the main components of which are hydrogen and helium. Nuclear bombs are being carried out all the time**. How could it be an entity.

    The sun is one"Balloons"It's made up mainly of hydrogen and helium, and its average density is about one-quarter of the Earth's density and about the same density of seawater. However, the core area of the sun is high temperature and high pressure, and the volume only accounts for 1 4, but the mass is more than half. The density reaches 160 grams cubic centimeter (but also in a dense gaseous state).

    If you don't count the core, the sun is a hot and thin sphere.

    If you burn coal, the sun burns 1.3 billion tons of refined coal in one second, and if the sun is a solid big briquette, it can only burn for 6,000 years In fact, the sun has been burning for 4.6 billion years, and it has just passed the year of "standing".

    The core temperature of the sun is 15 million degrees Celsius, and the surface temperature is 6,000 degrees Celsius, and at such high temperatures, all matter is gaseous.

    So the sun isn't solid, and if you ignore the heat, then the plane can move freely through the sun

    Solar atmosphere.

    According to the relative intensity of solar activity, the sun can be divided into two categories: the quiet sun and the active sun. The Tranquility Sun is a theoretically assumed spherically symmetrical hot gas sphere whose properties vary only with radius and are uniform in either sphere, with the aim of studying the general structure and general properties of the Sun.

    Under this assumption, the Sun is composed of a core, a radiation region, a troposphere, a photosphere, a chromosphere, and a corona, in order from the inside out. Below the photosphere is called the interior of the Sun; Above the photosphere is called the solar atmosphere.

    The Sun is the central body of the solar system and occupies the overall mass of the solar system. 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.

    The surface of the sun is:

    The Sun is a hot gas planet with no solid stars or cores. From the center to the edge, the sun can be divided into nuclear reaction zones, radiation zones, convective zones, and atmospheres. 99% of the sun's energy is produced by thermonuclear reactions in the nuclear reaction zone of the center.

    The solar center is extremely dense and hot, and it undergoes a thermonuclear reaction from hydrogen fusion to helium that is enough to last for 10 billion years, so the sun is currently in its middle age. The main components of the solar atmosphere are hydrogen (about 71% by mass) and helium (about 27% by mass).

    Hello landlord, I hope you can adopt, thank you.

    The main components of the sun are hydrogen (more than 70% point) and helium (more than 20%), and they are not in the three states of solid, liquid and gas that are common on our earth, but are in a plasma state due to high temperature and high pressure.

    Digression: I don't know if the landlord has studied chemistry and knows the word ion, ion is an atom with an electric charge after an atom gains or loses electrons) The atmosphere on the earth also has a layer of air in this state, 300-1000 kilometers above the ground, because it is excited by cosmic radiation and its own temperature (more than 1000 degrees Celsius), the air there is also in a plasma state. The so-called plasma state means that one atom of an object loses electrons, and another atom must gain electrons, so that two ions, one positive and one negative, are formed, so it is called the plasma state.

    In the center of the sun, due to the ultra-high pressure and ultra-high temperature environment, there is a fusion nuclear reaction in which four hydrogen nuclei collide together and fuse into a helium nucleus, but the chance of four hydrogen nuclei colliding together is certainly not very large, so the speed of nuclear fusion reaction in the center of the sun is also certain, although millions of tons of hydrogen fusion into helium per second, but the mass of the sun is too huge, its mass is kilograms, so it can maintain a life process of tens of billions of years.

    Enclosure (total mass.

    80% of the body is hydrogen, and the inner core (20% of the total mass) is helium, which the sun uses to destroy the electromagnetic force between atoms with force, causing hydrogen atoms to fuse into helium atoms, which emit light and heat. After 5 billion years, the mass of the helium atom is equal to the hydrogen atom, and the hydrogen shell of the sun will expand violently (expand 1 million times), occupying the area from Mercury to Saturn, and then the helium atom will continue to fuse into carbon atoms, in fact, carbon atoms can also fuse into oxygen atoms, but the mass of the sun does not increase but decreases after expansion, so the energy is not enough to make carbon fusion, so the sun that became a red giant finally shrunk into a white dwarf because of energy exhaustion.

    1.The Sun is the closest star to Earth and is the central body of the solar system. The mass of the solar system is concentrated in the sun. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all orbit (orbit) the sun.

    2.Sun sign, this is the most common topic of constellation on the lips of ordinary people. Indeed, in astrology, the configuration of the Sun is the most authoritative; It tells you about your personality and your life.

    But in some planets you may be more in character, but basically if the Sun strongly influences your personal chart, you will appear to be particularly brave, positive, confident, and not afraid of difficulties, and often be a leader among your peers. If the sun is in good position, such a person is usually normal and healthy. The sun governs human eyesight, the back, the arteries, and the heart.

    If you have particularly good vision in your right eye, the sun position usually works well.

    The Sun is a masculine representation, so the position of the Sun in a woman's horoscope tells us about the men she is related to during her life; Such as her father, boyfriend and husband. If the aspect is good, it means that the aforementioned relationship is centripetal and will be helpful to her.

    For a man, if the aspect is well matched, it means that he is often given an authoritative position, and the men around him are helpful and generally admired. In his life, he has a great chance of success and mends the flaws in his personal horoscope.

    3.In addition, the human astrological chart also has the moon sign, Venus, Mercury and other planets, asteroids, aspects, and houses.

    The nicknames of the sun are Xihe, Chilun, Zhu Xi, etc. At different times, the ancients would give different nicknames to the sun, such as the sun in spring is called Chunhui. And the summer sun is called the sun.

    The morning sun is called the rising sun, the morning light, the first day, the morning light, the morning halo, the first sun, and the first scene. The sun at dusk is called sunset, sunset, sunset, sunset, sunset, oblique sun, and sunset.

    The composition of the sun. The sun is composed of ordinary gases, of which hydrogen accounts for about 27%, helium accounts for about 27%, and other elements account for 2%. The sun can be divided into nuclear reaction opening area, radiation area and convection area, and solar atmosphere from the forward center.

    The atmosphere of the sun, like the atmosphere of the earth, can be divided into various layers according to different heights and different properties, that is, from the inside to the outside, it is divided into three layers: the photosphere, the chromosphere and the corona. The surface of the sun, which we usually see, is the lowest layer of the solar atmosphere, and the temperature is about 6,000 kilo. The sun is opaque, so we can't see the inner structure of the sun directly.

    Most of the materials that make up the sun are ordinary gases, of which hydrogen accounts for about 27, helium accounts for about 27, and other elements account for 2. From the center to the outside, the sun can be divided into nuclear reaction zone, radiation zone, convective macro galactic limb zone, and solar atmosphere. The atmosphere of the sun, like the atmosphere of the earth, can be divided into various layers according to different heights and different properties, that is, from the inside to the outside, it is divided into three layers: the photosphere, the chromosphere and the corona.

    The surface of the sun that we usually see, Bolu is the lowest layer of the sun's atmosphere, with a temperature of about 6000. It is opaque, so we cannot directly see the interior of the sun. However, astronomers have built models of the Sun's internal structure and physical state based on physical theories and the study of various phenomena on the surface of the Sun.

    This model has also been confirmed by studies of other stars, and it is credible, at least in the big picture.

    The Sun is the closest star to Earth and is the central body of the solar system.

    In the vastness of the starry world, the Sun's brightness, size, and material density are at moderate levels. It's just that because it's so close to Earth, it appears to be the largest and brightest object in the sky.

    Other stars are all very far away from us, even the nearest star, which is 270,000 times farther away than the Sun, and appears to be just a flickering point of light.

    The temperature of the sun's core, which reaches 15 million, is extremely high, and the pressure is also extremely high, allowing a thermonuclear reaction from hydrogen fusion to helium to take place, thus releasing enormous energy. This energy is then transmitted through the radiation layer and the troposphere to the bottom of the sun's photosphere, through which it radiates outward.

    Solar lifespan: about 5 billion years Solar age: about years.

    Most stars will shine brightly, and in layman's terms, due to mass, gravity and other factors, the sun is constantly undergoing nuclear fusion, which is the continuous explosion of atomic bombs on the surface. The reason why heat and light energy are generated.

    Disappear or not, there is no theory now. There is a theory that it will run out of energy, come once**, and then become a white dwarf a little smaller than the current Sun, premised on the reasoning that the evidence is the way other stars in the universe died. This theory is widely accepted.

    The sun is experiencing a lot of nuclear fusion, emitting a lot of electromagnetic radiation, including heat and light, that looks like it's burning. Matter will not disappear, but due to gravity, celestial bodies tend to collapse on their own, and after 5 billion years, the sun will become very massive but small in volume after being burned out, and the density will be infinite, and it will become a black hole, so it will not be observed, but it will not disappear.

    Fixed star.. The heat is due to the huge amount of energy produced by the fusion of hydrogen and oxygen inside. The energy must be disappearing.。。 I just don't feel it.

    。。。The sun is the sun。。 If you ask what a star is, a star is a giant gas ball in a state of nuclear fusion!

    That's right, the sun is gaseous, why not diffuse, because it's so huge so the gravitational pull brings all the gases together, so why not shrink into a point, because in nuclear fusion, the radiant heat is emitted from the inside out, and thus balances with the gravitational force to form a sphere.

    The sun is neither a gas nor a liquid, let alone a solid. In fact, the sun is plasmaic.

    Plasma and gas have many similarities, the plasma state is often referred to as the "supergaseous state", it has many similarities with gases, such as: there is no definite shape and volume, it is fluid, but plasma also has many unique properties. Ordinary gases are composed of electrically neutral molecules or atoms in a thermonuclear fusion reactor, which heats deuterium and tritium to become a plasma state, while plasma is a mixture of charged and neutral particles.

    First, plasma is a conductive body, but it can maintain electrical neutrality on a macroscopic scale comparable to the volume of gas; Secondly, there is no net electromagnetic force between the gas molecules, whereas there is a Coulomb force between the charged particles in the plasma.
