Chapter 163 How big is the solar system! It breaks your heart!
And the Southern Song Dynasty's Gaozong Zhao Gou.

After listening to the last song given by Tianmu, I felt a little unhappy.

"It is a critical period for the peace talks between the Song Dynasty and the Jin Dynasty."

"Isn't it confusing people if Tianmu gives this music now?"

"What is the name of this song? Serving the country with loyalty and loyalty?"

"I think it's just causing trouble!"

"If it affects my ability to bring peace to the Song Dynasty for a generation."

"That's a crime worthy of death!"

[Do you know the solar system? How big is the solar system? ]

In the center of the sky video, a beautiful orange-yellow fireball appeared.

The sun is marked on the sky.

The ancients could basically tell it just from the position of the sun.

The sun is the center.

In a few seconds, around the sun.

More planets appeared one after another.

They are labeled as Mercury, Venus, Earth, Mars, Jupiter, Saturn, etc.

A solar system model centered on the sun thus appeared before the ancients.

Obviously, this model of the solar system is very different from the ancient people's Hun Tian Theory and Gai Tian Theory.

However, due to the knowledge imparted by Tianmu during this period.

Although there is no direct explanation of the model of the universe, it has more or less revealed some relevant information.

This basically allowed the ancients to be mentally prepared.

The real solar system model is guessed to be very different from the traditional conception.

Plus the sun is a special place.

Great sun!
It occupies an outstanding position in the minds of all ancient people!
Therefore, when ancient people saw that the solar system was centered on the sun, they thought it was normal and did not feel too surprised.

There is no such thing as burning people.

Late Han Dynasty.

Zhuge Liang was also very curious about the astronomical content that was currently emerging.

This strong curiosity surprised even Zhuge Liang himself.

"In theory, knowing what's going on in the solar system won't make much difference to the governance of the country."

"But why am I so interested in watching it?"

“Looking up at the stars… is it human nature?”

While talking.

Zhuge Liang smiled and shook his head.

Put down the work in your hands, look at the sky with all your heart and soul, and think about the true meaning of the universe.

[The solar system model we currently display allows you to see the main celestial bodies in the entire solar system. ]

[In fact, this model is very wrong. ]

【But for the convenience of the audience to watch and intuitively understand. 】

【So we use this solar system model, which looks clear at first glance but is very different from the actual situation, to explain it.】

[The solar system, as the name suggests, is a galaxy with the sun at its center. ]

[In the solar system, except for the sun, which is the absolute core star. ]

[There are also eight planets, countless asteroids, comets and other celestial bodies. ]

【In this celestial system. 】

【There are countless celestial bodies of varying sizes and properties. 】

【But they all revolve around the sun. 】

[This is because the mass of the sun accounts for 99.8% of the entire solar system! ]

[Yes, even if you count the super-large planets like Jupiter and Saturn.]

[And countless asteroids. ]

[And in the distant Kuiper Belt, there are celestial bodies that humans have not yet explored. ]

[All added together, they only account for 0.2% of the mass of the entire solar system.]

【The sun has an extremely high surface temperature. 】

[The closest planet to the sun is Mercury, which takes only 88 Earth days to orbit the sun.]

[Mercury's perihelion is 4600 million kilometers from the sun, which is very close. ]

[Mercury is densely covered with craters and plains similar to those on the moon.]

[At the same time, the temperature difference between day and night on Mercury is also extremely large. 】

[On the side that is exposed to the sun during the day, the temperature can reach over 400 degrees, but at night it is only minus 180 degrees.]

[Throughout the day, the temperature difference between day and night was as high as more than 500 degrees! ]

[It can be said that it is very unsuitable for human habitation. ]

……

[After Mercury comes Venus, which looks very bright and very similar to the Earth. ]

[The ancient people in China and the West also gave Venus beautiful and pleasant names. ]

[But in reality, Venus is nothing more than another hell. ]

[Venus is 1.07 million kilometers from the sun, which can be said to be very far away. ]

【But Venus is even hotter than Mercury! 】

【It is the hottest planet in the entire solar system. 】

[Under the greenhouse effect of the thick atmosphere, the surface temperature of Venus has reached over 460 degrees! ]

[High temperature and high pressure are a terrifying pressure cooker, and it is obviously not suitable for human survival. ]

……

tomorrow.

Zhu Di looked at the contents of the sky curtain and was completely stunned.

Zhu Di once thought, what if the stars in the sky were other planets, other worlds.

Then it will definitely be far away.

But I didn't expect the distance to be so far.

And that extremely beautiful Venus is actually so terrifying!
"I'm afraid Shura Hell is just like this, right?"

"I ordered Zheng He to sail across the ocean, and the place he arrived at was already very far away."

"But compared to the distances between the stars in the sky, it's like standing still!"

"The place that we humans have spent our entire lives to walk through is so ethereal!" "Hey, I'm shocked."

The exaggerated astronomical figures have caused many people to doubt their lives.

And the sky continues.

[The Earth we live on is about 150 million kilometers away from the sun. ]

【The Earth, located in the habitable zone, breeds a large number of lives, including humans. 】

【And beyond the Earth is Mars. 】

[The distance between Mars and the sun is 2.27 million kilometers. ]

[Mars looks very similar to the conditions on Earth, and for a long time we suspected the existence of Martians.]

[The first step in searching for extraterrestrial civilizations is often Mars. ]

[But in reality, Mars is a very desolate desert planet.]

[People have launched several Mars probes, but no signs of life have been found so far. ]

【All that was found were desolate deserts, craters, and towering peaks.】

[The above planets are terrestrial planets in the solar system. ]

[Continue to move away from the sun and arrive at the asteroid belt more than 3 million kilometers away from the sun. ]

[The asteroid belt between Mars and Jupiter is a regular planet that has not cleared its orbit of other celestial bodies.]

【Instead, there are a large number of asteroids. 】

[Preliminary estimates put the number at more than 500,000.]

[The largest asteroid is called Ceres, and its diameter reaches 950 kilometers.]

[After passing through the asteroid belt, we arrived at the gas giant Jupiter. ]

【Jupiter is 7.3 million kilometers from the sun. 】

[The reason why Jupiter is called a gas giant planet is because Jupiter is really big. 】

[It is the largest object in the entire solar system after the sun. ]

[Even if we leave the solar system, Jupiter is still a big planet among all the planets known to mankind.]

[Its huge volume can accommodate more than 1,300 Earths! ]

[Thanks to the huge Jupiter for protection, we have resisted countless asteroids, comets and other potential killers from the depths of the universe. ]

【Hurry up and say thank you to Big Brother Jupiter. 】

[After Jupiter comes Saturn, which, like Jupiter, is also a gas giant.]

[And has Saturn's rings, which are mainly composed of dust, ice, and rocks. ]

[Very beautiful.]

[Further out are Uranus and Neptune.]

[They are both gas giant planets, but their sizes are much different from those of Jupiter. ]

[Of course it is still much larger than the Earth. ]

【Here are the eight planets in the solar system. 】

【Together with the sun before it, it can be said to be the most important celestial body in the entire solar system. 】

[One leader, the Sun, and eight main planets. ]

[Pluto, once the ninth largest planet, was expelled from the planet category at an astronomical conference in 2006 and became a dwarf planet.]

[If we explore further... we will reach the vast Kuiper Belt. ]

[The distance of the Kuiper Belt from the sun reaches 6.5 billion kilometers]

……

When I saw that the distance between the Kuiper Belt and the sun is 6.5 billion kilometers!
Zhuge Liang, who had been looking up at the starry sky, could not help but be deeply shocked!
I was so shocked that my heart was broken.

“This universe is so infinite!”

"Even the solar system is so vast, and I know that outside the solar system, there is an even vaster universe!"

"How vast are those places, and how far are they from us?"

Due to watching astronomical knowledge.

This caused Zhuge Liang to feel a little empty inside because of the shock.

Start doubting life.

But in fact, this is also a very normal phenomenon.

Many modern netizens also feel empty when watching videos about space and astronomy in the dead of night.

This leads to doubts about life and the world.

[Humanity currently knows very little about the Kuiper Belt.]

[All we know is that there are tens of billions of asteroids and rock fragments in the Kuiper Belt, which surround the main part of the solar system.]

[Originally, many people believed that the Kuiper Belt was the border of the solar system. ]

[But now we know that beyond the Kuiper Belt is the even more vast Oort Cloud.]

[The spherical Oort Cloud completely envelops the entire solar system. ]

[The distance between the Oort Cloud and the sun reaches one light year. ]

[The diameter of the entire cloud reaches two light years! ]

[It can be said to be a boundless existence. ]

[And only when we leave the Oort Cloud can we truly leave our solar system...]

[Now do you know how big the solar system is? 】

……

The video tells the story while also presenting imaginative images.

Many viewers were deeply shocked after watching it.

"It's so shocking! In the solar system, the sun is just as big as a speck of dust, but it drags the entire Oort Cloud!"

"If humans want to enter the cosmic age, they must first break through one light year."

What is a light year?

"When our ancestors said there is a universe beyond the sky, did they mean there is space beyond the solar system?"

"How is the solar system defined? The Oort Cloud is so much larger than the solar system itself, so does it all belong to the solar system?"

"Every time I finish watching a video about space and astronomy, I feel a sense of emptiness..."

《This is entering sage mode.》

"I seem to understand why there are people in many games and TV shows who come into contact with the truth of the universe and then go crazy."

"It is truly despairing to know something that you will never know!"

Just as modern netizens and ancient people were sharing EMO across time and space, marveling at the greatness of the universe.

A new sky appeared.

It drew everyone's attention back to the country.
