Tang Feng drove the Nautilus, quietly hovering in the airspace about 20 million kilometers away from the sun, staring at this planet that was wantonly swaying its light and heat to the outside world all the time, and his heart was also full of emotion. Pen ~ fun ~ pavilion www.biquge.info

The sun is undoubtedly very, very, very great in the minds of the people of the earth, from the primitive people of ancient times, they have worshiped the sun, and later slave society, feudal society and modern times, the people who worship the sun have always been endless!

From the moment the earth was born, the sun nourished the earth and its sister stars with its selfless light and heat, and after the birth of self-conscious human beings on the earth, human beings did not hesitate to give all kinds of beautiful words to this planet, which can be called the most important planet for mankind.

In the cultural inheritance of thousands of years in China, from such as "three-legged golden crow", "day mother", "nine yang", "xiyang", "sun lord", "sun lord", "purple gold bikui" ...... And so on, or good, or image, or noble titles, you can see how much ancient people respected and loved this fiery planet.

In foreign countries, there are many names that praise the sun, and even many people regard themselves as the spokesperson of the sun in the world. For example, the famous French king Louis XIV declared himself the reincarnation of the sun god and called himself the "Sun King".

Anyway, since ancient times, the fiery planet of the sun has always been the most respected and admired star of all mankind, and it has never been surpassed.

A long time ago, Tang Feng never thought that he would have such a day to conquer and completely control this most important planet for human beings, but now, the white fiery planet in front of him, which is only 20 million kilometers away from him, is his main goal this time, to be honest, Tang Feng is also very excited in his heart.

About 38 million kilometers behind the Nautilus, Mercury, which is less than 5,000 kilometers in diameter, is racing around the sun at a speed of nearly 48 kilometers per second. Only by maintaining such a speed can Mercury ensure that it is not pulled by the strong gravitational pull of the sun. In order to survive, Mercury must run at the fastest speed of all the planets in the solar system, or else it will be pulled closer, closer, and closer by the sun's huge gravitational pull......

Of course, Mercury will not crash into the surface of the Sun, because when Mercury is pulled closer to a certain distance, poor Mercury will be torn apart by these two huge forces like a pitiful mass of dirt under the combined effect of the huge gravitational pull of the Sun and the centrifugal force generated by its own revolution......

In the solar system, there is no planet that can resist the attraction of the sun, let alone Mercury, even if this happens to Jupiter, which is the largest and most massive, then the end is the same, that is, it is directly torn to pieces by the gravitational pull of the sun.

Although the Sun is a gaseous star, its mass is simply too large. In the huge solar system, the sun itself occupies 99.86% of the total mass of the entire solar system, including the earth, Jupiter, Saturn and other planets, moons, asteroids, dwarf planets, comets and other celestial bodies in the solar system The sum of the mass of all celestial bodies in the solar system is less than 1/713 of the mass of the sun......

Compared to the sun, the earth is like a sesame seed next to a basketball, and even Jupiter, the second largest celestial body in the solar system, can only be compared to the sun as a peanut and a basketball at best......

But who would have imagined that this yellow dwarf, which is 330,000 times the mass of the Earth, would be just a disordered nebula at the beginning of its formation?

According to the most popular nebula hypothesis about the formation of the solar system on Earth, the sun was formed from a chaotic nebula or molecular cloud.

4.6 billion years ago, a molecular cloud of several light-years in the cantilever of the constellation Orion of the Milky Way was quietly revolving around the galactic center. Only at that time, there was only an empty molecular cloud, and there was no sun, no eight planets, and many other celestial bodies.

If this molecular cloud had not been affected by external forces, it might have been rotating around the center of the silver all the time. But in the immediate vicinity of this molecular cloud, there have been several supernova explosions in succession. Supernova explosions are one of the few extreme astronomical phenomena in the universe, and their power is unimaginable.

As a result, one of the supernova explosions had an impact on this quiet molecular cloud. After the supernova explosion that was relatively close to the molecular cloud, the molecular cloud was affected by the shock wave generated by the supernova explosion, and in one of the superdense regions, the superdense region eventually formed a gravitational collapse.

Because angular momentum is conserved, the nebula rotates faster when it collapses. As the nebula continues to collapse, the atoms in it collide with each other more frequently, converting their kinetic energy into heat. Its mass concentration in the center is getting hotter than the surrounding disk. Then, after about 100,000 years, under the competition of gravity, gas pressure, magnetic field force and moment of inertia, the shrinking nebula flattened into a protoplanetary disk with a diameter of about 200 astronomical units, and formed a thermally dense protostar in the center - a star whose internal hydrogen fusion had not yet begun.

Although the real sun had not yet formed at this time, over time, about 50 million years later, the temperature and pressure of the protostar's core continued to increase, eventually leading to the occurrence of nuclear fusion, and a new main-sequence star was formed.

The formation of the main sequence star occupies more than 98% of the mass of the protoplanetary disk, and the other materials in the protoplanetary disk that are less than 2% of the mass gradually form the eight planets such as the Earth, Jupiter, Neptune and other celestial bodies in the solar system in an orderly manner.

In this way, after tens of millions of years of evolution, an otherwise ordinary molecular cloud finally formed a solar system headed by the sun boss.

Then in the next 4.6 billion years, under the leadership of the sun boss, the nascent solar system began to evolve in a better direction, among which, after billions of years of evolution, the earth, the blue rocky planet, finally gave birth to human beings......

And now, a certain human born from this blue rocky planet has obtained a magical star core by chance, and this human will carry this star core to launch the final conquest of the sun boss! (To be continued.) )
