The asteroid belt is one of the wonders of the solar system. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Outside the orbit of Mars and within the orbit of Jupiter, there are more than 100,000 asteroids floating in the wide field between the two planets. These seem to be the wreckage formed after the disintegration of a certain planet, just quietly in the empty space, revolving around the sun all the time.

Many people may think that this famous asteroid belt was formed after a planet was hit and disintegrated in ancient times, and the appearance of the asteroid belt is indeed similar to the appearance formed after the planet was blown up in many science fiction movies.

However, in fact, the reason for the formation of the asteroid belt has not been clarified until now, but a more common and accepted theory is that the asteroid belt was not formed by the disintegration of a formed planet after being impacted.

In the early days of the formation of the solar system, collisions caused by accretion processes were common, causing small particles to gradually gather to form larger clusters, and once they had gathered enough mass (the so-called microstars or stars), they could use gravity to attract surrounding matter. These stars can steadily accumulate mass to become rocky planets or giant gas giants.

When the solar system was just formed, a group of stars in the primordial solar nebula formed in this star field, and if these stars collided with each other for no other reason, they would slowly evolve into a rocky planet similar to the earth. In fact, most of the rocky planets such as Earth, Venus, and Mars need to go through this process for their formation.

But alas, in the outer part of the asteroid belt, a gas giant 318 times more massive than the Earth appeared - Jupiter. Of course, perhaps at that time, Jupiter did not have such a large mass, but the mass of Jupiter at that time was absolutely not to be underestimated. Moreover, there are many areas in which these stars in the asteroid belt are located in orbital resonance with Jupiter, and the force caused by strong orbital resonance will disturb the original orbit of these stars.

In this way, the stars sandwiched between Jupiter and the Sun were torn apart by two planets with very large gravitational forces, and at the same time, they were subjected to the orbital resonance of Jupiter's orbit, resulting in these stars that could have come together to form a new rocky planet, and could no longer coalesce together.

Moreover, because of the gravitational pull of the Sun and Jupiter, these fledgling stars collided violently with each other, which led to the creation of more debris and debris.

It can be said that the asteroid belt was "formed" by the joint action of the two killers of Jupiter and the Sun.

The entire asteroid belt contains more than half a million stars of various sizes, as well as countless interstellar dust. The largest star in this asteroid belt is the dwarf planet Ceres, which is only about 950 kilometers in diameter.

Ceres is the only star in the entire asteroid belt that meets the criteria of a dwarf planet, and it is also the largest and only planet in the entire asteroid belt that can achieve hydrostatic equilibrium. Therefore, this experimental trip to the asteroid belt, this Ceres was chosen by Tang Feng as the first target.

Of course, in addition to Ceres, Tang Feng also chose three other asteroids with the largest volume as experimental targets, which are Vesta, Homo sapiens and Justice.

As the only dwarf planet in the asteroid belt, Ceres is the largest and most massive in the entire asteroid belt.

The mass of Ceres accounts for almost one-third of the total mass of the entire asteroid belt, and it is the well-deserved king of the asteroid belt.

In the past, the American unmanned probe "Dawn" once made detailed observations of Ceres in a circular orbit of Ceres 13,000 kilometers away. If Tang Feng appeared before, this distance was already the closest distance for humans to Ceres, but now it was Tang Feng's turn, and this 13,000 km figure was immediately left far behind by Tang Feng.

Now Tang Feng is driving the "Nautilus", quietly hovering in the airspace about 100 kilometers above Ceres.

Not to mention that Ceres only has an escape speed of 0.51 km/s, even on Earth, with the powerful power of the "Nautilus", it can directly ignore the gravitational pull of the Earth.

Therefore, the Nautilus does not have to revolve around Ceres like other spacecraft at all, and the Nautilus hovers in mid-air so strongly. That's real hovering!

Looking down at this distance, the entire planet Ceres is in full view. This gray-black planet is similar to the Moon, but the surface looks far more hideous than the Moon, because on the surface of this dwarf planet, Tang Feng can hardly see a flat place, and there are craters everywhere.

It is no wonder that even the moon, a planet hundreds of millions of kilometers away from the asteroid belt, has been smashed into a pockmarked face by many meteorites on the surface because there is no protection of the atmosphere, not to mention Ceres, which is deep in the core area of the asteroid belt and has no atmosphere to protect the outer layer.

Without the protection of the atmosphere, it means that a random asteroid with a diameter of more than three meters or even smaller meteorites can easily have a close contact with Ceres.

It's just that Ceres, who was also smashed badly, if the pockmarked face of the moon is compared to this little brother, he is simply a handsome guy......

If it weren't for the purpose of experimenting on the star core, Tang Feng would not have chosen such a small dwarf planet as the preferred target.

In fact, even if the entire solar system is controlled, the star core is not used in this kind of star field where birds don't and chickens don't lay eggs, and the total mass of the entire asteroid belt is not even one-tenth the size of the moon, and the star core even skips this asteroid belt when it controls the entire solar system.

There is no way, the disabled are not strong, and even the star core can't look down on such an existence.

"Man, this dwarf planet is the first target I chose for you, you can control this dwarf planet while trying to control other asteroids. There are hundreds of thousands of asteroids here, and you can choose whatever you want. Of course, if you don't like these asteroids, there are three spare, relatively large asteroids not far from there. ”

The core seemed to be watching the dwarf planet beneath its feet, and after a while it said, "You can take me to see the three alternative asteroids again." Although this asteroid near Ceres can also be controlled, it is of little value, and it is more experimental to control a larger asteroid. ”

Tang Feng nodded, activated the "Nautilus", and flew towards the Vesta Star "not far away".

Vesta is actually not close to Ceres, tens of millions of kilometers are absolutely there, but in front of Nautilus, the distance of tens of millions of kilometers is just a blink of an eye...... (To be continued.) )
