Chapter 1723: Nemesis

The first thousand eight hundred and ninety-seven chapters of Nemesis
Zhao Zhongyao smiled and said, ‘Yes! This little sun is indeed beautiful. It is not only beautiful, but also not so dazzling. We can observe it up close. ’
'Yes! This little sun is much gentler than our big sun. Feifei said so too.
When Zhao Zhongyao and Feifei talked like this, Tiantian took a closer look at the entire small solar system. She felt that in this small solar system, there were some asteroids moving around this central celestial body.
Among these asteroids, one seems to be relatively large, not far from the center of the small solar system. It is not very far from the central celestial body and can receive the light of the central celestial body.
It's just that Tiantian doesn't care about these things. After all, this is a mini solar system similar to the real solar system.
‘This is really a gentle sun! Said the same every day.
At this time, Zhao Zhongyao took out the amethyst gem and took a look at it. He originally thought that the star map on the amethyst gem should have not been updated. After all, I just watched it and nothing has changed. It has only been a while, and there may not be any changes.
However, Zhao Zhongyao now wants to see what else changes on the star map. After all, they now need the guidance of the star map to find the twelfth amethyst gem.
Although Zhao Zhongyao just took a casual look, he saw that the text on the star map had changed.
However, after this change, there are still five words-Nemesis Star.
‘The Nemesis Star! After reading it, Zhao Zhongyao couldn't help but read these five words.
Feifei and Tiantian were discussing about the central celestial body of the mini solar system, and inadvertently heard the five words spoken by Zhao Zhongyao-Nemesis.
When Feifei heard this, she looked at Zhao Zhongyao in confusion and asked, ‘Dad, what are you talking about? ’
‘The Nemesis Star! Zhao Zhongyao repeated it again.
'what! Nemesis Star! What does it mean? Said Feifei puzzledly.
‘This is a new tip I saw on the star chart, and I don’t understand what it means. Zhao Zhongyao said this first.
At this moment, Tiantian said in a clever way, ‘dad, does the hint on the star chart mean the little sun in this mini solar system? ’
After Zhao Zhongyao heard what Tiantian said, something suddenly occurred to him.
He felt a sense of enlightenment, and immediately understood what was going on.
‘Yes, the Nemesis star on the star chart is the magical little sun we see. Said Zhao Zhongyao.
‘Then why is it called Nemesis Star! Feifei asked inexplicably.
‘This is because this little sun is inextricably linked to many disasters on our planet. Said Zhao Zhongyao.
After hearing what his father said, Feifei and Tiantian still felt very puzzled. They didn't understand the relationship between this ‘little sun’ and the disaster on the earth. After all, this little sun is hundreds of billions of kilometers away from the earth! How could it cause some disasters to the distant earth.
So Feifei asked again, ‘Dad, what the is going on, can you explain it to us in detail. ’
After hearing what Feifei said, Zhao Zhongyao thought for a while and said, ‘Actually, it is like this. Some astronomers on our planet have always had a bold guess. They guessed that there was a mysterious celestial body in the distant Oort Cloud.
This is a dwarf star much smaller than the sun. Although it is a star, its mass and volume are much smaller than that of the sun, and it is not a star in the true sense.
Generally speaking, in the Milky Way, there are two or three central celestial bodies in many stellar systems, or even more celestial bodies are focused together.
And like our sun, in a star system, a star system with only one central celestial body is considered to be a relatively rare star system.
As a result, some astronomers believe that those star systems where only one central celestial body can be observed. There may also be companion stars. It's just that this companion star is very far away from the central star, and its volume and mass are far less than the central celestial body, so we think that there is only one central celestial body in this stellar system, and there is no companion celestial body.
Our solar system, although there is only one central celestial body. However, on the edge of the solar system, there may be a dwarf star smaller than the sun, and it may be a companion star of the sun. It's just because the distance is too far to emit dazzling light, our astronomers on Earth cannot observe it, so we think that there is only one central celestial body in the solar system, and there is no companion star.
However, our planet has experienced billions of years, every tens of millions of years, a serious astronomical disaster will occur. The main thing is that some small comet celestial bodies will form serious meteor shower events on the earth when they fly near the earth.
If among these meteor showers, some of the relatively large and small celestial bodies have not been completely burnt down after passing through the earth's atmosphere, but can still fall to the ground, they will cause serious damage to the surface of the earth.
Since the existence of life on the earth, these beings have been constantly suffering from some serious astronomical disasters, which have brought a great impact on the evolution of life on the earth.
After some research, it was discovered that every 30 million years, there will be a serious asteroid hitting the earth. Sixty million years ago, the astronomical event that caused the extinction of the dinosaurs on the earth was also caused by an asteroid with a diameter of ten kilometers hitting the earth.
Therefore, some astronomers feel that it must be due to a certain mysterious celestial body that appears near the sun every 30 million years, causing serious effects on some asteroids near the solar system, leading to some asteroids. , Deviate from the original orbit, some of them may hit the earth.
In this case, these asteroids that hit the earth will have a profound impact on the evolution of life on the earth.
Therefore, some astronomers think that in the huge Oort cloud very far away from the sun, there may be a mysterious celestial body-the sun companion star hidden.
Since this celestial body is much smaller in size and mass than the sun, it can only revolve around the sun. It's just that it is very far away from the sun, and it may take 30 million years to orbit the sun for a week.
The orbit of this small star may also be a huge ellipse. Its aphelion is very far away from the sun, but the perihelion may be relatively close to the sun.
