Chapter 1637: Ganymede

Chapter 1825: Ganymede
Although this planetary ring is not as obvious as Saturn. But Jupiter does have a huge planetary ring. This planetary ring can only be seen when you observe it closely, and it is also very beautiful.
Feifei looked at this beautiful planetary ring now, and said, ‘Dad, how did you know how this planetary ring of Jupiter was formed? ’
After hearing Feifei’s words, Zhao Zhongyao said, ‘Generally speaking, the planetary ring of a planet is due to the huge planet and its gravitational force. In this case, if one of its satellites orbits around it is closer to the parent planet. Then the huge gravitational force of this mother planet can tear this moon into pieces. Therefore, when this satellite is broken into pieces, it will become a planetary ring of this mother planet.
Of course, the planetary rings of large planets like Jupiter and Saturn are not the result of crushing one satellite, but the result of crushing many satellites. Especially the planetary rings of Saturn are the result of many satellites crushed.
The planetary rings of Jupiter, relatively speaking, are not very obvious. This shows that the planetary rings of Jupiter are only the result of the crushing of a few satellites. ’
Feifei heard his father's words and nodded and said, ‘In this way, this planetary ring of Jupiter is not as beautiful as that of Saturn. ’
‘Yes, Jupiter’s planetary rings are not as beautiful as Saturn’s. However, we don’t have to worry, when we get the sixth amethyst gem, we will go to Saturn to find the seventh amethyst gem. Zhao Zhongyao looked at Feifei and said.
‘Okay, let’s hurry up and find the sixth amethyst gem! After hearing what Zhao Zhongyao said, Feifei wanted to quickly see what the planetary rings of Saturn looked like!
‘Feifei, don’t you see Jupiter’s Great Red Spot? Zhao Zhongyao looked at Feifei and said.
When Feifei heard her father's words, she realized that she still needs to see Jupiter's Great Red Spot! So he looked at Zhao Zhongyao again and said, ‘Dad, then let’s go and see Jupiter’s Great Red Spot! ’
So, Zhao Zhongyao piloted the spacecraft again and continued to approach Jupiter. Although they are already in the planetary ring of Jupiter. But in fact, they couldn't see many planetary particles in this planetary ring. That is to say, dozens of planetary particles can be seen flying around his spacecraft.
Zhao Zhongyao is now driving the spacecraft again, passing through this planetary ring. Then, he came to a place 60,000 kilometers away from Jupiter.
When the spacecraft arrives at this place, some instruments in the spacecraft will be affected, and even the spacecraft itself will shake a little.
Feifei still asked inexplicably, ‘Dad, what’s the matter, why is our spaceship trembling a little. ’
Zhao Zhongyao said, ‘this is because we are already in Jupiter’s magnetic field. Therefore, the instruments on our spacecraft are affected by Jupiter's strong magnetic field. ’
‘Then can our spacecraft continue to approach Jupiter? Feifei said again.
‘Of course, we can continue to approach Jupiter. Although Zhao Zhongyao knows that Jupiter has strong gravity. But their spacecraft, as long as they can become some of Jupiter's moons, can slowly approach Jupiter.
So, Zhao Zhongyao piloted the spacecraft again and continued to approach Jupiter. Soon, they were only 10,000 kilometers away from Jupiter.
Although, they are still 10,000 kilometers away from Jupiter. But compared to the very huge Jupiter, this distance is already very close. Almost, it is equivalent to an altitude of one thousand kilometers above the earth.
Zhao Zhongyao let the spacecraft fly over Jupiter's Great Red Spot, and then looked at Feifei and said, ‘Feifei, come and take a look. This is Jupiter’s Great Red Spot. Can you see it clearly now? ’
At this time, Feifei, I saw this great red spot of Jupiter, which was really spectacular. It turned out to be a very huge cyclone. The diameter of this cyclone is about the size of an earth.
‘Dad, this Great Red Spot is really spectacular! No wonder we can observe it on the earth. It is really huge. Feifei looked at the huge red cyclone above Jupiter and said.
‘Of course, such a large cyclone is really very rare on this Jupiter. Zhao Zhongyao said again.
‘Dad, why is this huge cyclone red! Feifei asked inexplicably.
Hearing Feifei’s words every day, he also echoed, ‘Dad, this huge cyclone is really beautiful. But why is it red? ’
After hearing what Feifei and Tiantian said, Zhao Zhongyao thought for a moment and said, ‘I think it’s probably because of this huge cyclone that can release the energy inside Jupiter. So, it will become red. Because Jupiter is a planet close to the star. There is a high temperature core inside, which can release huge energy. And this Great Red Spot may be a window through which Jupiter's internal energy is cast outside. ’
After hearing what Zhao Zhongyao said, Feifei knew how this great erythema was formed. For this great erythema, why it was red, also knew some of the reasons.
It's just that this big erythema is nothing good. After watching for a while, Feifei said, ‘Dad, there is nothing good about this Great Red Spot, should we go to Ganymede? We must quickly find the sixth amethyst gem, so that we can go to Saturn to see the beautiful Saturn rings. ’
Zhao Zhongyao heard Feifei's words, and said, ‘Okay, let’s go to Ganymede! I hope we can successfully find the sixth amethyst gem. ’
After Zhao Zhongyao finished speaking, he flew away from Jupiter in his spacecraft, and then flew towards Ganymede.
At this time, Feifei wanted to know some knowledge about Ganymede. So I looked at Zhao Zhongyao and said, ‘Dad, can you tell us about Ganymede again. ’
Zhao Zhongyao heard Feifei's words and said, ‘Okay then! I will tell you more about Ganymede. ’
Next, Zhao Zhongyao gave Feifei some more knowledge about Ganymede.
Ganymede is a satellite orbiting Jupiter with an orbiting period of about 7 days. Sorted by distance from Jupiter from near to far, it ranks seventh among all the moons of Jupiter and third among the moons of Galileo. It maintains a 1:2:4 orbital resonance relationship with Europa and Io.
Ganymede is the largest moon in the solar system. The diameter is larger than Mercury, and the mass is about half of Mercury.
