Chapter 1809 Wisdom Star

Zhao Zhongyao drove the spacecraft and landed in the middle of this huge basin. When the spacecraft stopped on the ground, Zhao Zhongyao and Feifei saw a layer of sand on the ground outside.

‘Dad, how can this place be like this, it’s different from other places. Feifei said as he looked at something like sand outside.

Zhao Zhongyao looked at the situation outside and said, ‘This shows that this place has been severely attacked. This basin, or pothole, was formed by an asteroid impact. Only the asteroid that hit Juno was also very large, and it directly knocked out a part of Juno, and then left such a huge basin or pit at the point of impact. ’

After hearing what my father said, Feifei knew what was going on. He looked at his father and said, ‘No wonder Juno has become a very irregular asteroid. It turns out that it had been hit by another asteroid long ago. ’

‘Yes, many asteroids in space have collided with other asteroids. After all, this asteroid belt is a relatively dense area of ​​asteroids. Due to the relatively high density of asteroids, their orbits will stagger each other. As a result, they may collide together during flight. Zhao looked at his son and explained again.

After hearing what Zhao Zhongyao said, Feifei understood what was going on. It's just that he still doesn't understand what the sand-like thing outside is.

‘Dad, what are these things like sand outside? Feifei looked at Zhao Zhongyao and asked.

At this time, Zhao Zhongyao said again, ‘These things may have been formed by the dust that was generated during the impact that slowly fell to the ground. Because this place is an impact crater, so the dust will slowly gather in this impact crater. As a result, the sand-like things we see now are formed. ’

After hearing what my father said, Feifei understood what these things were like sand. He looked at his father again and said, ‘then are we still looking for amethyst gems here now! Will there be amethyst gemstones on this Juno? ’

‘I’m unlikely to have it, let’s go and see another well-known asteroid! Zhao Zhongyao felt that it was unlikely that there would be amethyst gemstones on this **** of marriage, so he looked at his son again and said.

‘Okay, let’s take a look on Zhi Shen Xing! After hearing what my dad said, Feifei wanted to visit Zhi Shen Xing.

‘Let’s go, let’s go to Zhi Shenxing After hearing what his son said, Zhao Zhongyao flew the spaceship to Zhishen star again.

It's just that Zhisheng is hundreds of millions of kilometers away from Juno. If they want to fly to Zhisheng, they still have to fly for a while.

Therefore, when flying to the Zhishen star, Feifei looked at Zhao Zhongyao again and said, "Dad, can you tell us about the Zhishen star first, let us know this Zhi Shen Xing has a general understanding. ’

After hearing Feifei’s words, Zhao Zhongyao said, ‘human beings don’t know much about this wisdom star, and it’s difficult to see the shape of this asteroid in astronomical observations. There is also relatively little information about this asteroid.

Therefore, I don't know much about this Zhishen star. However, I still know some knowledge about Zhi Shen Xing. Now I will tell you about the knowledge of Zhi Shen Xing! ’

After finishing talking, Zhao Zhongyao told everyone about what he knew about this wisdom star.

Zhi Shen is the first asteroid discovered by humans after Ceres (the only dwarf planet in the asteroid belt). The estimated mass is 7% of the asteroid belt. With a diameter of 560 kilometers, Sosapius is slightly larger than Vesta, but its mass is 10–30% lighter than Vesta, so Sosapius is the second-heaviest asteroid in the asteroid belt. The Papillon may be the largest irregular celestial body in the solar system (that is, its own gravity cannot make its appearance smooth), or it may be a remnant protoplanet.

Sophia is the third largest asteroid, similar in size to Vesta (not sure), but its lower mass is worth noting. If the outer Neptune celestial bodies are not counted, the Pseoris is the largest celestial body in the solar system that has not been directly observed (with telescopes or probes) on its surface. It may also be the largest irregular object in the solar system, that is, its own gravity is not enough to gather celestial bodies into a spherical shape.

Although Chirami is very large, as a celestial body in the middle of the asteroid belt, its orbit is quite inclined and has a large eccentricity.

The results of photometry in recent years have shown that the inclination of the rotation axis of Sosapius is close to 60° (the earth is only 23.5°), which means that the length of sunshine in different regions on Sosapius has strong seasonality. On the other hand, astronomers have not yet been able to agree on the direction of the rotation of Sosapius.

Through occultation and photometric methods, astronomers can indirectly guess the shape of Zhi Shen. In addition, some studies have pointed out that the spectral characteristics of Zhirenxing are similar to some carbonaceous chondrites.

There are some memorable milestones in the history of Sosapius observations: The occultation of Sosapius has been observed several times, and the event of May 29, 1983 was the best observation of an asteroid occultation. 140 observers made this observation, carefully measuring the time of the masking, and helping to measure the precise diameter.

Observations on May 29, 1979 found that Zhisheng may have a satellite about 1 km in diameter, but it was not confirmed. In 1980, the observation report of the speckle interferometer stated that there was a large satellite with a diameter of 175 kilometers, but the existence of this satellite was later rejected. It used to be used to estimate the mass by reflecting the radar signals from the spacecraft orbiting Mars on the surface of Zhisheng, showing tiny perturbations affected by the movement of Mars.

So far, no telescope has ever observed the features on the surface of the planet Sophisticated, and no spacecraft has ever detected the planet Sophisticated. If the future Dawn project can successfully detect Ceres and Vesta, the mission may be extended to Zhisheng, but because of the high inclination of the orbit, it will be more difficult to detect other asteroids.

After Zhao Zhongyao talked about this knowledge, he looked at everyone and said, ‘because human beings don’t know much about this wisdom star. I couldn't learn more about this wisdom star. And now we are going to personally go to see this wisdom star. We want to see what this mysterious star of wisdom looks like. ’

After hearing what his father said, Feifei also said, ‘Yes, since humans don’t know much about this asteroid, we can go to see this asteroid now. We can witness it with our own eyes. ’

‘Okay, let’s speed up and fly to Zhi Shen Xing! After Zhao Zhongyao finished speaking, he drove the spacecraft to the mysterious Wisdom Star again.

Soon, their spacecraft flew to a place several hundred kilometers away from this wisdom star. From this place, the appearance of the entire Zhi Shen star can be seen completely.

The shape of the whole Zhi Shen star is a very irregular shape, and the outer color is relatively bright, basically yellow, with some black in it.

Although the outside of Zhiren is irregular, it still feels better than Vesta and Juno in terms of its appearance.

As soon as he saw the appearance of Zhi Shen, Zhao Zhongyao said, ‘It turns out that this Zhi Shen, as human astronomers guessed, is a huge carbon-plasmid meteorite. ’

Zhao Zhongyao said a professional term-carbon plasmid meteorite. After letting Feifei listened, he asked inexplicably, ‘Dad, what kind of meteorite is the carbon-plasmid meteorite you are talking about? ’

After hearing what his son said, Zhao Zhongyao said, ‘I still know a little bit about this carbon-plasmid meteorite. This kind of meteorite may be related to the origin of life on Earth. ’

‘Oh, it’s also related to the origin of life on earth. Then you can quickly talk about the relationship between this kind of carbon-plasmid meteorite and life on earth. Feifei became very curious after hearing what his father said.

‘Ok, let me explain first what is a carbon-plasmid meteorite. Next, Zhao Zhongyao explained to everyone what a carbon-plasmid meteorite is.

Carbonaceous chondrites are chondrites rich in water and organic compounds, accounting for only about 5% of known meteorites. Its main ingredients are silicate, oxide and sulfide. It has two minerals, olivine and serpentine, which is a major feature of it.

Carbonaceous chondrites are a kind of meteorites with special carbon-containing material elements in the meteorite family. It is said that they are special because they have high scientific research value and practical significance.

They represent the evolution and causative matter in the most primitive solar system, and they are the solid matter that survived the initial formation of the solar nebula.

They preserve some information on the condensation, evolution, and genesis of solar nebulae, and their mineralogy and chemical composition reflect the formation and evolution history of early solar nebulae, planets, asteroids, and stars.

The characteristics of carbonaceous chondrites retained during the hydrous alteration process are closely related to the low-temperature evolution of early solar nebulae. Therefore, carbonaceous chondrites are witnesses to the formation and evolution of early solar nebulae.

Carbonaceous chondrites of different chemical compositions represent the evolution products of different regions of the solar nebula. They are formed in different regions and the distance between them is different from the sun, and their physical and chemical conditions will also change from oxidation to strong reduction.

In recent years, the academia has discovered many different amino acids in some carbonaceous meteorites. These extraterrestrial amino acids have been continuously discovered. In addition to studying some of their isotopic changes and differences, studying these special interstellar materials can be Helping us find alien life and uncover the origin of life provides important clues.

Carbonaceous chondrites, also known as C-type chondrites or "CCS", are relatively non-carbonaceous chondrites. The lithofacies of carbonaceous chondrites contain a certain amount of carbon material, which is named after the carbonaceous material. Carbonaceous chondrite or carbonaceous meteorite.

Carbonaceous chondrites are members of the chondrite family with a relatively high degree of oxidation and reduction. Because their chemical characteristics are also closest to the materials formed in the early days of the primitive sun and solar nebula, carbonaceous chondrites are the most studied solar system planets and stars. Ideal specimen.

Because of its volatile organic chemicals and water, it has not been severely heated (above 200°C) since its formation.

Carbonaceous chondrites are believed to best preserve the components of the solar nebula that formed the solar system. Its main ingredients are silicate, oxide and sulfide. It has two minerals, olivine and serpentine, which is a major feature of it.

Looking at Feifei, Tiantian and Qu Yuqian, Zhao Zhongyao told them some knowledge about carbon-plasmid meteorites.

After listening to the knowledge his father said, Feifei had a general understanding of the giant carbon-plasmid meteorite, Zhishen.

Tian Tian also looked at this asteroid that is more beautiful than Vesta and Juno and said, ‘Dad, we can see the beauty of this asteroid now. But I don't understand, why is this asteroid named Zhisheng? ’

After hearing what his daughter said, Zhao Zhongyao smiled and said, ‘Maybe it’s because she looks better! Therefore, it is called Zhishenxing. ’

Hearing what my father said every day, I still said in a puzzled way, ‘why, do you have to be named after the star of wisdom if you look good? ’

‘Because long and good-looking women are smart! Therefore, this asteroid is also named after Athena, the goddess of wisdom in Western mythology. Because it is named after the goddess of wisdom, it is called Zhishenxing. Zhao Zhongyao looked at his daughter and explained.

After listening to my father's words every day, I have a clear understanding of why this Zhishen star wants Zhishen.

‘Dad, it makes sense for you to say that. Such a beautiful asteroid should really be named after a goddess. ’Said this again every day.

It’s just that Zhao Zhongyao heard Tiantian’s words and said again, ‘I feel that the reason why this Zhishen star is called, should have little to do with Athena. More importantly, such planets are closely related to intelligent life on the earth. If it is because of this asteroid named Zhisheng, then it would be more appropriate. ’

Hearing what my father said every day, I still said in a puzzled way, ‘dad, why is this, why do you say that! ’

Feifei also looked at his father and said, ‘dad, then tell me, what does this wisdom star have to do with life on our planet. ’

After hearing what Feifei and Tiantian said, Zhao Zhongyao said, ‘Yes, I feel that all the organic matter on our planet may come from these carbon-plasmid meteorites that are the same as Zhishen. ’

Feifei and Tiantian looked puzzled when they heard what their father said. Because they don't understand what dad said. So Feifei asked again, ‘Dad, why do you say this, and what basis do you have! ’
