Chapter 1879 Flying to the Oort Cloud

After hearing what his father said, Feifei also smiled and said, 'Well, let's go to the edge of the solar system to see it! I'm really curious now, and I don't know what the edge of the solar system is like. '

I didn't speak for a long time every day, and at this time I looked at Zhao Zhongyao curiously and asked, 'Dad, what do you think the edge of the solar system looks like, can you describe it for us first. '

After hearing what Tian Tian said, Zhao Zhongyao said, 'I don't know much about this, but I still know a little bit. Now let me tell you what the edge of the solar system looks like! '

After finishing speaking, Zhao Zhongyao thought about it again and said, ‘According to the research of some scientists, at the edge of our solar system, there is an extremely huge Oort cloud composed of countless ice and snowballs. '

When Feifei and Tiantian heard Zhao Zhongyao mention the'Oort' cloud, they were a little puzzled. They didn't understand what the'Oort' cloud Zhao Zhongyao was talking about.

‘Dad, what exactly is this Oort cloud you are talking about? Feifei was a little puzzled, looked at Zhao Zhongyao and asked.

‘Yes, dad, please explain to us what is going on with this Oort cloud! Tiantian also looked at Zhao Zhongyao and asked.

At this time, Zhao Zhongyao looked at the two children again and said, "This Oort cloud is a very large comet home composed of countless comets." Here is the edge of the solar system.

Our entire solar system, in fact, is a very special star system surrounded by a very huge Oort cloud.

It is precisely because our solar system has a huge Oort cloud that the planets in our solar system are very safe to operate.

It can be said that the human beings on our earth have also benefited from this Oort cloud. If the Oort cloud is not in the outer reaches of the solar system, protecting the safety of the earth and some other large planets, the entire solar system will suffer some serious problems at any time. Attack of the rogue planet. '

When Zhao Zhongyao said this, he stopped for a while, wanting to see if Feifei and Tiantian had anything else to ask.

At this moment, Feifei asked again in puzzlement, 'Dad, what is the wandering planet you are talking about, this seems to be the first time I have heard this term. '

After hearing Feifei's words, Zhao Zhongyao explained, "Wandering planets are planets that leave their parent star and fly freely in the galaxy." '

'Oh, how could this be, how could these planets have left their parent stars! ’ Feifei was still a little puzzled.

'This is because, in a galaxy, there are many stars that will not live for tens of billions of years like the sun. Many stars, due to their large size, the hydrogen element inside them burns very quickly, and their lifespan is also very short. Generally speaking, the life span of these large stars with a mass several times that of the sun is only hundreds of millions of years, or tens of millions of years.

Although hundreds of millions or tens of millions of years are very long compared to the lifespan of human beings. But compared to the sun, it is very short-lived.

These short-lived stars also form planets around them. However, when these stars 'die', the planets around them may be directly 'swallowed' by the parent star. Of course, it is also possible to lose the gravity of the parent star and then wander around in the galaxy.

Generally speaking, those planets that are relatively close to the parent star will cause the parent star to burst out and be directly destroyed. However, for those planets that are farther away from the parent star, it is possible that the gravitational waves generated by the parent star after the parent star erupts are directly pushed into the interstellar space due to the sudden eruption of the parent star.

These planets, pushed into interstellar space by the powerful gravitational waves of their parent stars, end up as rogue planets. They will remain wandering in the galaxy until they are captured by another star.

Some of these large planets and satellites near our solar system may have wandered from interstellar space to the vicinity of the solar system, and then were captured by the sun.

Even the moon, which is the closest to our earth, may be a wandering planet. It may also have flown from the distant interstellar space to the vicinity of the solar system billions of years ago, and then it was captured by the strong gravity of the sun.

The moon may be a planet at the beginning, but because its orbit is relatively close to the earth, in an accidental close contact, the earth was captured and then became a satellite of the earth.

Of course, this is just a hypothesis, how the moon came into being. At present, there is no unified theory in the world. Although there are various hypotheses, none of them can perfectly explain the existence of the moon.

But anyway, the solar system is relatively safe and stable. Because at its edge, there is a solar system 'shell' composed entirely of ice and snow comets. It is precisely because the solar system has this 'shell'. When the solar system travels through the Milky Way, it will not be attacked by some stars from the interstellar space.

The life on our earth is also due to the protection of the Oort cloud, so that it can continue to survive. '

Zhao Zhongyao looked at Feifei and Tiantian, and said what he knew, some knowledge about the Oort cloud.

After Zhao Zhongyao said this, Feifei and Tiantian had a general understanding of this'Oort' cloud.

‘Dad, so to speak, this Oort cloud is a very magical celestial body. Feifei looked at Zhao Zhongyao and said.

'yes! Hearing what my dad said, I want to go to Oortyun to see it right away. ’ Said the same every day.

'Okay then, we'll start flying to Al

Teyun! ' After hearing what the two children said, Zhao Zhongyao drove the spaceship again and flew towards the very distant Oort Cloud.

It's just that when the spacecraft starts to fly from the inner space of the solar system to the outer space, it makes people feel that the outer space of the solar system is very different from the inner space.

In the inner space of the solar system, some relatively large celestial bodies can still be seen to some extent. But when the spacecraft flew to the outer space of the solar system, it felt like there was nothing there, and there was nothing, as if it had flown into the interstellar space.

Feifei watched the spaceship flying for a long time, but there was nothing there, so he said strangely, 'Dad, why is there no celestial body in this space! Could it be that we have already flown to the outer space of the solar system. '

Zhao Zhongyao looked at the monitor in the cockpit of the spacecraft and said,'We haven't flown to the outer space of the solar system yet, we are still in the inner space of the solar system. '

‘Dad, how can the space here be empty! What's the matter, we should see some celestial bodies too! ’ Feifei said again in such a puzzled way.
