There are eight planets in the solar system. There are two special planets in the eight planets that are most concerned by scientists. One is the beautiful and unusual earth, which is the home of human survival and a unique planet of life. We can’t see the beauty of the earth standing on the earth. Only when we walk out of the earth can we really appreciate the difference of the earth. Even if the earth is billions of kilometers away, it is as small as a grain of dust, but it can still be found in many dust. The reason is its unique beauty. Even if it becomes dust, it is also a beautiful blue dust .
In addition to earth, another unique planet is Jupiter. For Jupiter, I believe many people know that it is the largest planet in the solar system. It can hold 1300 earths, and its mass is 2.5 times the total mass of the other seven planets.
Although Jupiter is so huge, it is a very flexible celestial body, and its natural speed is also the fastest in the solar system. Huge mass and super fast rotation speed make Jupiter have a very strong gravity. For a celestial body, its strength is measured by the strength of gravity. The strong gravity can devour many other celestial bodies, constantly expand its own mass and become more powerful.
Scientists have found that Jupiter may play a very important role in the early period of the solar system. It may devour many celestial bodies in the early period. When scientists observe extrasolar systems through telescopes, they find that many star systems have super earth, and their orbits are closer to the stars than mercury’s.
However, the solar system is the only exception. Mercury is relatively backward, and there is no super earth. Scientists believe that the early solar system may have had a super earth, but later was swallowed by Jupiter. Through simulation, scientists found that the number of planets in the early formation of the solar system may be much more than now. At that time, a lot of interstellar dust formed stars and other planets.
Jupiter, Saturn and other massive planets are among the first to form. They were all born near the center of the solar system, close to the sun. Because this position is the most dense area of interstellar material, only a large amount of material can form a huge planet, so the early Jupiter was not at this position, but very close to the sun.
Since Jupiter was formed earlier, it has a large mass and strong gravity. When it was born, it began to devour the surrounding celestial bodies, so in the early solar system, celestial body collisions occurred all the time. Through constant collisions, the materials and celestial bodies near the solar system were basically devoured by Jupiter, and finally it was ejected further by the huge gravity of the sun.
Even if Jupiter has reached a farther place, it is still swallowing all kinds of celestial bodies passing by it by its hegemonic gravity. We can see that the number of Jupiter’s moons is as many as 60, most of which are captured by Jupiter.
Many star systems outside the solar system are crowded near the orbit of mercury, which has more celestial bodies and materials. However, the orbit of mercury in the solar system is very clean. The reason for this may be that it was engulfed by Jupiter in the early days. Fortunately, it was ejected by the sun’s pull later. Otherwise, even mercury may not be able to survive later.
Maybe it is a natural factor that Jupiter constantly devours the celestial bodies in the orbit of mercury, but it is precisely because of such an accident that life and civilization on earth are born. As we all know, it is not easy for a planet to give birth to life and complete a series of evolutions all the way to give birth to intelligent life. It needs to meet many conditions.
One of the important external conditions is stability and safety. Only when we are in a very stable and safe position, can we have enough time to meet the birth, evolution and evolution of life. In the area from the sun to the earth, the number of celestial bodies is very small and it looks very clean, so there is no need to worry about the collision of any celestial body from mercury.
When Jupiter reaches its present orbit, it forms a strong protection for the earth. Jupiter’s strong gravity has attracted all kinds of asteroids and comets to the earth, making them unable to form an impact threat to the earth. This gives the earth a very stable external environment. Without the protection of Jupiter, if asteroids hit the earth from time to time, life would not be able to complete the evolution, and eventually human beings would be born.
This point can be understood by looking at Mars. Through a large number of explorations on Mars, scientists believe that the early Mars was also a beautiful planet like the earth, and it may also have given birth to simple life. But because Mars is in a very unsafe position, because it is too close to Jupiter, this position just formed an asteroid belt.
From time to time, asteroids in the asteroid belt break away from orbit and collide with Mars, which destroys the geological structure of Mars and finally loses its magnetic field. Without the protection of the magnetic field, Mars lost its atmosphere, lost its surface liquid water, and finally became desolate.
Jupiter’s contribution to the earth is very great, so it’s natural for us to pay close attention to it. Only by knowing more about Jupiter can it better protect the earth and mankind. Of course, Jupiter is not the same as Mars. We can land on Mars for more explorations, but these explorations are powerless in front of Jupiter.
It is possible that Jupiter is not a pure gas planet, and there may also be a rocky core inside it. And Jupiter’s atmosphere is too thick. The super thick atmosphere divides Jupiter’s atmosphere into three parts, one is the outermost gaseous part, the other is the liquid hydrogen in the middle layer, and finally the deepest solid hydrogen.
It is very difficult for the probe to go deep into Jupiter’s atmosphere. It needs to face more and more powerful pressure and super strong storms. With the current technology of human beings, it is impossible to go deep into Jupiter’s atmosphere for exploration. Therefore, we know very little about Jupiter, not even skin. Only by striving to develop science and technology and having stronger scientific and technological power, can we really go into the interior of Jupiter to explore and really uncover the mystery of gas giant planets.
