Chapter 1825 Ganymede

.. Chapter 1825 Ganymede

Although this planetary ring is not as obvious as Saturn. But Jupiter does have a giant ring. This planetary ring can only be seen to exist when observing it at a close distance, and it is also very beautiful.

Now Feifei looked at this beautiful planetary ring, and said, 'Dad, you know how the planetary rings of Jupiter were formed, right? '

After hearing Feifei's words, Zhao Zhongyao said, "Generally speaking, the rings of a planet are due to the fact that this planet is very huge and its gravitational force is also very strong." In this case, if one of its satellites orbits around it, it is relatively close to the parent planet. Then the huge gravitational force of this parent planet can tear up this satellite. Therefore, when this satellite is smashed to pieces, it will become a planetary ring of this parent planet.

Of course, the planetary rings of giant planets like Jupiter and Saturn are not the result of a single satellite being smashed, but the result of many satellites being smashed. Especially Saturn's planetary rings are the result of the smashing of many satellites.

Jupiter's rings, relatively speaking, are not very obvious. This shows that Jupiter's planetary rings are only the result of the smashing of a few moons. '

After listening to what his father said, Feifei nodded and said, 'From this point of view, the planetary rings of Jupiter are not as beautiful as those of Saturn. '

‘That’s right, 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, then let’s hurry up and find the sixth amethyst gemstone! After hearing what Zhao Zhongyao said, Feifei wanted to quickly see what Saturn's planetary rings look like!

‘Feifei, haven’t you seen Jupiter’s Great Red Spot? 'Zhao Zhongyao looked at Feifei and said.

After hearing what his father said, Feifei realized that he still wanted to see Jupiter's Great Red Spot! So, he looked at Zhao Zhongyao again and said, 'Dad, let's go see Jupiter's Great Red Spot! '

So, Zhao Zhongyao drove the spaceship again and continued to approach Jupiter. Although they are already in the planetary rings of Jupiter. But in fact, they can't see many planetary particles in this planetary ring. That is to be able to see dozens of planetary particles flying around his spacecraft.

Zhao Zhongyao is now driving the spaceship again, passing through this planetary ring. Then, it came to a place 60,000 kilometers away from Jupiter.

When the spaceship arrived at this place, some of the instruments in the spaceship would be affected, and even the spaceship itself would shake a bit.

Feifei asked puzzled, 'Dad, what's going on, why is our spaceship shaking a bit. '

Zhao Zhongyao said, ‘This is because we are already in Jupiter’s magnetic field. Therefore, the instruments on our spacecraft are affected by the strong magnetic field of Jupiter. '

'Then can our spacecraft continue to approach Jupiter? ’ Feifei said again.

'Of course we can, we can continue to approach Jupiter. 'Although Zhao Zhongyao knows that Jupiter has a strong gravitational force. But their spacecraft, as long as they can become some of Jupiter's satellites, can slowly approach Jupiter.

So, Zhao Zhongyao drove 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 a thousand kilometers above the earth.

Zhao Zhongyao let the spacecraft fly over the Great Red Spot of Jupiter, and then looked at Feifei and said, "Feifei, take a look, this is the Great Red Spot of Jupiter, can you see it clearly now." '

At this time, Feifei saw the Great Red Spot of Jupiter, which was really spectacular. It turned out to be a very huge cyclone. The diameter of this cyclone is almost as large as the earth.

‘Dad, this Great Red Spot is really spectacular! No wonder we can observe it from Earth. It's really huge. ’ Feifei looked at the huge red cyclone above Jupiter and said.

'Of course, such a large cyclone is indeed very rare on this Jupiter. Zhao Zhongyao said again.

‘Dad, why is this huge cyclone red! ’ Feifei asked puzzledly.

After listening to Feifei's words every day, he also echoed and said, 'Dad, this huge cyclone is really beautiful. But why is it red? '

After hearing what Feifei and Tiantian said, Zhao Zhongyao thought for a while and said, 'I feel that it may be because this huge cyclone can release the energy inside Jupiter. So, it will be red. Because Jupiter is a planet close to a star. There is a high-temperature core inside, which can release huge energy. And this Great Red Spot may be a window for Jupiter's internal energy to be released outside. '

After listening to Zhao Zhongyao's words, Feifei also knew how this big red spot was formed, and also knew some reasons why this big red spot was red.

It's just that this one Great Red Spot isn't anything to look at. After looking at it for a while, Feifei said, 'Dad, there is nothing interesting about this Great Red Spot, should we go to Ganymede? We have to find the sixth amethyst gemstone quickly, so that we can go to Saturn to see the beautiful Saturn rings. '

After hearing Feifei's words, Zhao Zhongyao said, "Okay, let's go to Ganymede to have a look!" I wish we could

Successfully found the sixth amethyst gemstone. '

After Zhao Zhongyao finished speaking, he drove the spacecraft away from Jupiter, and then flew towards Ganymede.

At this time, Feifei still wants to know some knowledge about Ganymede. So, he looked at Zhao Zhongyao and said, Dad, can you tell us about Ganymede again. '

After hearing Feifei's words, Zhao Zhongyao said,'Okay then! I'll tell you a little more about Ganymede. '

Next, Zhao Zhongyao told Feifei some more knowledge about Ganymede.

Ganymede is a satellite orbiting Jupiter with a revolution period of about 7 days. Ranked from closest to farthest from Jupiter, it ranks seventh among all the moons of Jupiter and third among the Galilean satellites. It maintains a 1:2:4 orbital resonance with Europa and Io.

Ganymede is the largest moon in the solar system. The diameter is larger than that of Mercury, and its mass is about half that of Mercury.
