In the universe, why are gaseous planets not blown away by the solar wind?

The solar wind will reduce its speed and temperature along the way from the sun, so that it reaches the vicinity of the gaseous planet, the solar wind radiation and impact force is already very small, and it has no great impact on the planet, and the gaseous planet itself has a strong gravitational pull, so even the gaseous planet will not be blown away by the solar wind.

The force of the solar wind is too small relative to the gaseous planet to blow the gaseous planet.

Because the gravitational pull of the planet is very strong, and generally this kind of planet is not small, it will not be blown away by the solar wind.

There is a phenomenon in the arrangement of the eight planets of the solar system, that is, the rocky planets (terrestrial planets) are arranged on the inside, and the gas planets (Jupiter) are arranged on the outside, such as Mercury, Venus, Earth, and Mars, which are closest to the sun, are all rocky planets, while Jupiter, Saturn, Uranus, and Neptune are all gas planets, so why is there such an arrangement?

In the entire solar system, the sun is the absolute center of gravity, and its mass accounts for the entire solar system, and the eight planets and other asteroids, dwarf planets, moons, comets, etc. add up to the other, so the total amount of other matter in the solar system is really pitifully small except for the sun.

With such a huge mass of the sun, it also produces a very strong gravitational force, so the gravitational center of all celestial bodies in the solar system is the sun, that is, if an object is allowed to fall at will, then in the solar system it will inevitably fall in the direction of the sun, and eventually it will fall on the sun.

It's like if we put a glass of water on the table and then put some small things in it, then these little things will inevitably sink to the bottom of the cup, and we can understand the bottom of the cup as where the sun is.

So if we put the density of the small things in the cup is different, then their position in the cup is not the same, if it is a small iron ball, it will inevitably sink to the bottom of the cup, and if it is wood and plastic balls, they can even float on the water surface of the cup, this is due to their different densities, the density of the iron ball is the largest, so it will sink to the bottom of the water, the density of the plastic ball is relatively small, if it is the same as the density of water, then it will float in the middle of the water, The wooden balls are basically floating on the water.

The density of the planets in the solar system also varies, with rocky planets generally having higher densities and gaseous planets having less densities. The densest of the eight planets is Earth, followed by Mercury, Mars and Venus, but because Earth has a thicker atmosphere, if the Earth's 200-kilometer-thick atmosphere is also included, then its density is about the same as Mercury. Therefore, the orbit of Mercury in the solar system is closest to the Sun, while Venus, Earth, and Mars are located in different orbits outward, Jupiter, Saturn, Uranus, and Neptune are all gas planets, and the density is much smaller than that of rocky planets, for example, Saturn is less dense than water, so the four gas planets are all located in orbits farther from the Sun.

<> However, the reason for density is not the only reason, the position of the planets in the solar system will also be affected by the gravitational pull of other celestial bodies and the impact of larger asteroids, such as scientists believe that the position of the four gas planets Jupiter, Saturn, Uranus and Neptune was not in the current orbit, Jupiter is likely to form in the inner solar system (some say that it comes from outside the orbit of Neptune), and later came to the outer part of the solar system due to collision with larger celestial bodies. The position of Saturn is affected by the gravitational pull of Jupiter, and the position of Uranus and Neptune is affected by the gravitational pull of Jupiter and Saturn, so there are actually many factors that contribute to the position of the planets in the solar system.

Because gas planets are less dense and have less gravitational pull, the outer reaches of the solar system are all large gas planets.

Because gas planets were born at the beginning, they were all gaseous and lightweight, and they were limited by the sun's gravity, so they could only drift outside the solar system and slowly accumulate to form gaseous planets, so that their orbits were fixed at a distance from the sun.

I think it's because there's a lot of matter around the sun, and the matter that's very close to it becomes solid because of gravity, and some of the things that are far away become gaseous because of the heat.

The temperature of the surface of the sun is as high as 5,600 degrees Celsius, and the temperature of the center is about 20 million degrees Celsius. The sun is neither solid nor liquid but a state of plasma. So the sun itself is a ball of plasma.

Any object that comes into contact with the sun is quickly vaporized, and then forms an ionic state that is absorbed by the sun and becomes a part of the sun. So human probes can't get close to the surface of the sun.

Sun.

Two reasons.

One is that Jupiter is very massive, able to attract gas tightly together, and will not be thrown out by the centrifugal force of Jupiter's rotation, nor will it be blown away by the solar wind.

Jupiter is the largest and fastest-rotating planet among the eight planets in the solar system. It has a mass of one-thousandth the Sun, 318 times the mass of the Earth, and twice the mass of the other seven planets in the Solar System combined. This also allows Jupiter to escape at kilometers per second, the largest of any planet in the solar system.

In comparison, the Earth's escape velocity is only a kilometer second.

The second is that the solar wind is not so powerful that it will not blow away the planet's atmosphere.

The solar wind is a stream of charged particles from supersonic plasma ejected from the Sun's upper atmosphere. Although the solar wind is also called wind, its density is not large, and in general, in the interplanetary space near the Earth, there are a few to dozens of particles per cubic centimeter. Such a weak wind, although very fast, 350 450 kilometers per second, cannot blow the atmosphere on the surface of the planet.

Venus, which is closer and less massive than the Earth, has a dense atmosphere on its surface and is not blown away by the solar wind, let alone Jupiter, which is farther from the Sun, more massive, and more gravitational. The solar wind is powerless against Jupiter gas.

Jupiter's own gravitational pull can cause its own gas to gather up. And the light pressure of the solar wind is too small and insignificant.

No, getting too close to the star will evaporate

After the universe is large, the most basic matter produced is hydrogen atoms and hydrogen molecules. After billions of years of accumulation, the early nebula clusters were formed. After 1 million years, the center of the nebula cluster will form a gas-like disk with the highest density and highest temperature, and the temperature of this disk will increase for a short time under the continuous contraction of its own gravity, and the nuclear fusion reaction (hydrogen and helium reaction) will begin to occur in the state at about 10 million degrees Celsius, which will form a star.

To put it simply, a large number of gases are constantly approaching the center, causing the internal pressure to increase and the temperature to increase; When the pressure and temperature reach a certain level, hydrogen and helium undergo nuclear fusion reactions. This led to the formation of stars.

In the same way that the Earth's atmosphere does not run away, the reason for this is the presence of gravity. The sun can pull the earth by gravity, and it can also pull its own gas.

In an ideal state, the gas will diffuse freely, but when the gravitational force acts, it is no longer an ideal state, and the gas does not slow down and obeys the laws of the ideal state.

Because it's hydrogen, like Jupiter. I recommend you to watch "Traveling to the Edge of the Universe" for the same reason that the Earth's atmosphere does not run away, due to the presence of gravity. The sun can pull the earth by gravity, and it can also pull its own gas.

In an ideal state, the gas will spread freely, but when the gravitational force acts, it is no longer an ideal state, and the gas no longer obeys the laws of the ideal state. The sun's internal gravitational field is very large, and this gravitational force the sun's external matter to keep squeezing inward and shouting hail, and the sun's life is halfway through, and at some point in the future the sun will sink itself and form a black hole ---in its final form. Or eventually become a supernova** and be reborn.

Any object can emit light as long as it is under certain heat or temperature conditions, and the frequency, wavelength or color of light emitted by different objects is also different, so someone can find the corresponding object according to the spectrum. Sunlight is a hybrid light source that can find any corresponding substance in sunlight. In fact, the sun is a hot solid planet, and the surface temperature of the sun is very high, and the high temperature may also make the surface of the sun covered with a layer of hot lava, and this hot lava is constantly thrown into the sky and falls, forming the so-called corona. Sunspots are relatively dark regional phenomena formed by low temperatures in local areas of the sun.

In conclusion, from the spectral analysis, I think; The Sun cannot be a planet made of gas and thermonuclearized.

The Sun, like all large celestial bodies, is multi-layered. The sun's heliosphere has a solid surface underneath the hot gas, and the inner core of the sun is also solid. It would be a mistake to think of the sun as a whole large balloon.

The values of high temperature and pressure in the interior of the sun, calculated according to the principle of gravitational and fluid pressure, are not realistic. Moreover, the high temperature and radiant energy on the surface of the Sun are not produced by the so-called thermonuclear reactions, but from the electromagnetic potential energy inside and the radiant energy of the interstellar matter outside. The solid surface of the sun is the product of the synthesis of yin and yang of the inner and outer substances of the sun, just like the solid surface of the earth.

The large amount of hydrogen and helium on the surface of the sun reflects the pattern of step-by-step nucleosynthesis of cosmic matter, and Zheng Juanfan is of course the majority of light elements, and has nothing to do with the so-called thermonuclear fusion, which does not exist at all.

I'm really convinced by this question, first of all, I ask you where the wind comes from outside the cosmic celestial bodies that almost dig into the vacuum? Besides, don't you know that there is gravity, and if there is really air blowing over, it has long been captured by a celestial body as large as the sun and become a part of itself.

You're talking about the wind of the Earth's atmosphere, right? Where is the wind in the universe?

Presumably, the landlord clan Xun is still in this elementary school. Do you know? In order for light to be distorted (not refracted against), the gravitational force needs to be so great that you can't imagine it, and the so-called stupid "wind" is just a small amount of air pressure difference on the earth, compared to the speed of light (300,000 kilometers per second), the "wind" is weakly exploded.

Because the sun is more than 1 million times larger than the earth, the gravitational force of the sun is at least tens of thousands of times greater than the earth's gravitational force, so that the wind is more than enough to dig and talk, so it is blown away by the wind.

There is no air in the universe, so how can the wind come from if the air does not flow?

Wind is a phenomenon of air movement, and there is a vacuum in space, so there is no wind generated.

The universe is a very large individual, and there are so many planets in between, and the Earth is one of the largest planets, and there are Mars, comets, and so on, but there is also a kind of planet that is a gaseous planet. To know inAlmost all of the stars are gaseous planets, but not all of them are made of gas, and many of them are mainly composed of rocks and metals

1. Whether the gaseous planet will be blown away The main reason why the gaseous planet is called a planet is that it has a large mass content and strong gravitational force, which makes the gas binding of the planet relatively firm, and some gaseous planets with relatively large mass rely on gravity to make their mass larger, and after the mass is large, the gaseous planet will naturally not be blown away. <>

2. Why won't the gas planet be blown away, and the gas planet won't be blown awayLet's talk about blowing it first, as far as the planet body is concerned, if you want to be blown away, the strong wind you need is very large, that is, it needs a huge amount of energy. Of course, there are also such strong winds in the universe, such as the star wind on the star and the wind energy that erupts on the nova are relatively large, and generally due to the huge energy on this kind of star, many stars will be blown away or stripped by this strong wind, and the extent of the stripping depends on the wind speed of the location. <>

3. What is the solar wind? Many people don't know about the solar wind, but I have to say that the wind speed of the solar wind is very terrifying, for example, if the solar wind blows on the earth, it may open the earth's crust to expose magma, and eventually become a piece of planetary debris. Because the wind speed of the solar wind is tens of thousands of times that of the Earth wind, our understanding of the solar wind is very limited.

At the same time, the solar wind can carry electric particle radiation, which will cause certain damage to the human body, reduce people's immune function, and can also cause some lesions in our body, which is also more emotionally fluctuating, so the solar wind is actually very bad for the human body.

In summary, it is not very likely that gaseous stars in the universe will be blown away, and whether a planet will become planetary debris is also affected by many factors, and it cannot be one-size-fits-all.
