Chapter 1897 Nemesis Star

Zhao Zhongyao said with a smile,'Yes! This little sun is really 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 also said the same.

While Zhao Zhongyao and Feifei were talking like this, Tiantian took a closer look at the entire small solar system. She felt that there were some asteroids in this small solar system moving around this central celestial body.

Among these asteroids, one seems to be relatively large, and it is located not far from the central celestial body 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 I don't care about these things every day. After all, this is a mini solar system similar to the real solar system.

'What a gentle sun it is! ’ Said the same every day.

At this time, Zhao Zhongyao took out the amethyst gem casually and took a look. He originally thought that the star map on the amethyst gem should not have been updated. After all, after reading it just now, nothing has changed. It's only been a while, and there may not be any changes.

However, Zhao Zhongyao now wants to see what changes will happen on the star map. After all, they now need the guidance of the star map to find the twelfth amethyst gemstone.

Although Zhao Zhongyao just looked at it casually, he saw that the text on the star map had changed.

However, after this change, there were still five characters——Nemesis Star.

‘Nemesis star! After Zhao Zhongyao read it, he couldn't help but read these five words.

Feifei and Tiantian were discussing the central celestial body of the mini solar system, and inadvertently heard the five words that Zhao Zhongyao said-Nemesis Star.

When Feifei heard it, he looked at Zhao Zhongyao in puzzlement and asked, 'Dad, what are you talking about? '

‘Nemesis star! Zhao Zhongyao repeated it again.

'What! Nemesis Star! What does it mean? ’ Feifei said puzzledly.

‘This is a new hint I saw on the star map, and I don’t understand what it means. ' Zhao Zhongyao said this first.

At this time every day, he had an idea and said, 'Dad, does this reminder on the star map refer to the little sun in this mini solar system? '

Zhao Zhongyao suddenly thought of something after hearing what Tian Tian said.

He felt a sense of enlightenment, and immediately understood what was going on.

‘That’s right, the nemesis star on the star map is the magical little sun we saw. Zhao Zhongyao said so.

‘Then why is it called Nemesis Star! ’ Feifei asked again puzzled.

‘This is because this little sun is inextricably linked to many disasters on our planet. Zhao Zhongyao said so.

After listening to what their father said, Feifei and Tiantian were still very puzzled. They didn't understand what this "little sun" had to do with the disasters on the earth. After all, this little sun is hundreds of billions of kilometers away from the earth! How can it create some disasters to the distant earth.

So Feifei asked again, 'Dad, what is going on, can you explain it to us in detail. '

After hearing Feifei's words, Zhao Zhongyao thought for a while and said, 'Actually, that's the case. Some astronomers on our planet have always had a bold guess. They speculate that there is a mysterious celestial body in the distant Oort cloud.

This is a dwarf star much smaller than the sun. Although it is said to be a star, its mass and volume are much smaller than that of the sun, so it is not a star in the true sense.

Generally speaking, in the Milky Way, many stellar central celestial bodies are two or three, or even more celestial bodies are gathered together.

And like our sun, in a star system, there is only one central celestial body, which is considered a relatively rare star system.

Therefore, some astronomers believe that those star systems in which only one central object is observed. There may also be a companion star. It’s just that this companion star is very far away from the central star, and its volume and mass are far inferior to the central celestial body. Therefore, we think that there is only one central celestial body in this star system, and there is no companion celestial body.

Although our solar system has only one central celestial body. However, at the edge of the solar system, there may be a dwarf star smaller than the sun, which may be a companion star of the sun. It's just because the distance is too far away and it can't emit dazzling light, our astronomers on the earth can't observe it. Therefore, we think that there is only one central celestial body in the solar system, and there is no companion star.

However, our earth has experienced a serious astronomical disaster every tens of millions of years during billions of years. The main reason is that some small comets, when they fly near the earth, will form serious meteor shower events on the earth.

If some relatively large and small celestial bodies in these meteor showers are not completely burned up after passing through the earth's atmosphere and can still fall to the ground, they will cause serious damage to the earth's surface.

Since the existence of life on the earth, these lives have been continuously attacked by some serious astronomical disasters, which have greatly affected the evolution of life on the earth.

After some research, it was found that every 30 million years on the earth, there will be a serious asteroid impact on the earth. Sixty million years ago, the astronomical event that caused the extinction of the dinosaurs on Earth was also due to

It happened when an asteroid with a diameter of ten kilometers hit the earth.

Therefore, some astronomers felt that it must be because of a certain mysterious celestial body, which would appear near the sun every 30 million years, which would have a serious impact on some asteroids near the solar system, causing some asteroids to , deviate from the original orbit, and 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 believe that in the huge Oort cloud that is very far away from the sun, there may be a mysterious celestial body-the solar companion.

Since this celestial body is much smaller than the sun in volume and mass, 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.

And the orbit of this small star may also be a huge ellipse. Its aphelion is very far away from the sun, but its perihelion may be relatively close to the sun.
