Chapter 1822 Flying to Jupiter
'Okay, we have got the fifth amethyst gem, we can go back to the spaceship. Zhao Zhongyao looked at everyone and said.
'Okay, let's go back to the spaceship! ’ Feifei also said the same.
So, Zhao Zhongyao took Feifei, Tiantian and Qu Yuqian, and they returned from the lake to the shore. Once on the shore of the lake, they boarded the spaceship again.
After returning to the spaceship, Feifei couldn't wait to look at Zhao Zhongyao and asked, 'Dad, we've got the fifth amethyst gemstone, so where should we go now. '
After hearing Feifei's words, Zhao Zhongyao said, 'Since we have obtained two amethyst gemstones in this asteroid belt, we are going to fly out of this asteroid belt. We're going to fly to Jupiter. '
‘Dad, the sixth amethyst gem we are looking for is on that planet. Feifei looked at Zhao Zhongyao again and said.
After hearing Feifei's words, Zhao Zhongyao said,'I've seen the star map before. The sixth amethyst gem we are looking for is on Ganymede. So, we should leave this asteroid belt now and set off for Jupiter. '
After hearing what his father said, Feifei said, 'Okay, let's start to Jupiter! '
'Okay, we're off to Jupiter. After Zhao Zhongyao finished speaking, he drove the spaceship and set off to Jupiter.
It's just that this Ceres is now more than 200 million kilometers away from Jupiter. It will take a while for the spacecraft to fly to Jupiter. So, Feifei looked at Zhao Zhongyao again and said, 'Dad, before we reach Jupiter, tell us something about Jupiter first! '
After hearing Feifei's words, Zhao Zhongyao said, 'Okay, since we are going to Ganymede, we still want to know about Ganymede's home planet! '
So, next, Zhao Zhongyao told everyone some knowledge about Jupiter.
Jupiter is the fifth closest planet to the sun and the largest planet in the solar system, with 79 known moons in 2019. The ancients had known this planet for a long time, and the Romans named it after the chief god Jupiter. In ancient China, Jupiter was called Sui Xing, because it takes about 12 years to orbit the celestial sphere, which is the same as the earthly branch. In the Western Han Dynasty, Sima Qian, the author of "Historical Records?? Tianguanshu", found that the year star was blue from actual observations, which was connected with the "five elements" theory and officially named it Jupiter.
Looking at Jupiter from the earth, the apparent magnitude can reach -2.94, and the shadow of objects can already be illuminated on the ground. Jupiter is on average the third brightest object in the night sky, after the Moon and Venus (Mars can briefly outshine Jupiter at certain points in its orbit).
Jupiter is a giant planet with a mass one-thousandth that of the sun, but 2.5 times the mass of the other planets in the solar system combined. Jupiter is mostly hydrogen, but one-tenth of a molecule of helium, but a quarter of its mass; it may have a rocky core and heavy elements, but no well-defined solid surface. Due to its rapid rotation, Jupiter appears as an oblate spheroid. The atmosphere is divided into different regions and belts according to latitude, and turbulence and storms act at the junction of each other. The most notable example is the Great Red Spot, a monstrous storm that has lingered since it was first seen by telescope in the 17th century. There are also faint planetary rings and a strong magnetosphere surrounding Jupiter, including 4 Galilean satellites discovered in 1610, and 79 satellites have been discovered as of December 2019. Ganymede is the largest of these, with a diameter larger than the planet Mercury.
Jupiter is a giant liquid hydrogen star. As the depth increases, at least 5,000 kilometers from the surface, liquid hydrogen forms under high pressure and temperature. It is speculated that the center of Jupiter is a core region containing materials such as silicate and iron, and the material composition and density are in a continuous transition.
Jupiter is one of the four gas planets (also known as Jupiter-like planets): a planet that is not mainly composed of solid matter. It is the largest planet in the solar system, with an equatorial diameter of 142,984 kilometers. The density of Jupiter is 1.326g/cm??, ranking second among the gas planets, but far lower than the four terrestrial planets in the solar system.
Jupiter is releasing enormous amounts of energy into its cosmic space. It emits twice as much energy as it receives from the sun. This means that half of the energy released by Jupiter comes from its interior. There is a heat source inside Jupiter. Some people think that its thermal energy may be transformed from gravitational potential energy when Jupiter was formed, and was convected on the surface by liquid hydrogen on a large scale.
As we all know, the reason why the sun continuously emits a lot of light and heat is because the nuclear fusion reaction is going on inside the sun all the time, and a large amount of energy is released during the nuclear fusion process. Jupiter is a huge liquid hydrogen planet. It already has incomparable natural nuclear fuel. In addition, the central temperature of Jupiter has reached 280,000 K, which has the high temperature conditions required for thermonuclear reactions. As for the high-pressure conditions required for thermonuclear reactions, judging from Jupiter’s contraction speed and the energy emitted by the sun and the accretion characteristics of energy-carrying particles, after billions of years of evolution, Jupiter’s central pressure can reach that of the initial nuclear reaction. required stress level.
The composition of Jupiter and the sun is very similar, but it does not burn up like the sun because its mass is too small. To become a star like the sun, Jupiter needs to increase its mass to 80 times its current size. According to astronomers' calculations, only when its mass is greater than 7% of the sun's mass can it undergo fusion reactions and emit light and heat.
Jupiter's magnetic field is 14 times stronger than Earth's, ranging from 4.2 gauss at the equator to 10 to 14 gauss at the poles, the strongest in the solar system (except for sunspots). Surrounding the planet is a loose planetary ring system and a strong magnetosphere (Jupiter's magnetic field is very strong, and the magnetic field on the side facing away from the sun is even
extended to the orbit of Saturn). This field is thought to be created by vortices -- swirling motions of conductive material -- and the liquid metallic hydrogen at its core.
Volcanoes on Io's moon release large amounts of sulfur dioxide, forming rings of gas along the moon's orbit. These gases are ionized within the magnetosphere, producing ions of sulfur and oxygen. Together with hydrogen ions originating in Jupiter's atmosphere, they form a plasma sheet at Jupiter's equatorial plane. These sheets of plasma rotate with the planet, causing a distorted dipole magnetic field that enters the magnetic plane. The electric current in the plasma sheet generates a powerful radio signal, causing bursts in the range 0.6 to 30 MHz.
Jupiter's magnetosphere has a large range and complex structure, and the huge space between 1.4 million and 7 million kilometers away from Jupiter is Jupiter's magnetosphere.
