Why did the ancient Chinese discover Jupiter in 2000?

In ancient times, even if there was no high technologyAstronomical telescopesWhen there are great changes in the planets, they can be observed with the naked eye

More than 2,000 years ago, in 48 B.C., ancient Chinese astronomers witnessed with the naked eye the appearance of a new star about 1,600 light-years away, a phenomenon recorded in the Book of Han

Inside:In April of the first year of the early Han Dynasty, the guest star was as big as a melon, blue and white, inNandouThe second star in the east, four feet in the east.

In 1981, Xi Zezong was inActa Astrophysical Sinicapublished an article in **".Two thousand years before GalileoGanderThe Discovery of Europa。This ** is from the Tang Dynasty"Kaiyuan Zhanjing".In a few sentences, Xi Zezong argues and speculates that Gander during the Warring States period had discovered Wood Marinade in 364 BC. Since then, the astronomical community has quickly carried out experimental tests on this, whether it is simulation verification or actual observation verificationThis new finding is confirmed.

During the Warring States Period, there were many astronomers whose names could be investigated in our country, the most famous of which was the Qi State.

of Shi Shen and Wei State.

Gander is the most famous, but it is a pity that none of their writings have survived. Fortunately, this part was preserved in the Tang Dynasty's Kaiyuan Zhanjing, which records a passage from Gander when he spoke about Jupiter, one of which reads: ".If there is a small red star attached to its side, it is called an alliance.", which attracted the attention of Xi Zezong. Combined with the context of Gander's words, it should mean that the "little red star" is attached to Jupiter and has been combined with Jupiter to form a system.

In addition, "red" is light red, which also matches the color of the four Ganymede. It is precisely because of this analysis that Xi Zezong thinks that what is recorded here may be that Gander discovered Gande

In fact, Ganymede was discovered by Gander, an astronomer from China's Warring States period, nearly 2,000 years before Galileo. He is the author of two books, "The Classic of the Stars of the Year" and "Astronomical Astrological Horoscope", but unfortunately they have been lost. In the twenty-third volume of the "Kaiyuan Zhanjing" compiled by the Tang Dynasty astronomer Qu Tan Siddha, there is such a record: "Gan Shi said:

The age of the single cast, the setig is in the mao, the year star is in the son, and the bearded girl, the void, the danger of the morning and the evening in, its shape is very large and bright, if there is a small red star attached to its side, it is called an alliance".

The ancients had nothing to do, looking up at the sky every day, at that time the natural environment was good, the air observation conditions were superior, and the stars visible to the naked eye could not be seen. And all the ancient civilizations attached great importance to astronomy, not only the Chinese discovered Jupiter.

The ancient people's understanding of the solar system began with the Sun, the Moon, and the five planets (Mercury, Venus, Mars, Jupiter, and Saturn), which were called planets because they were observed to move slowly relative to the other stars in the sky

Because in ancient China, there were also people who made astrological observations and discovered the planet Jupiter.

Because the Chinese have loved to explore new events since ancient times, they were able to discover Jupiter.

This should be the wisdom of the ancients, who discovered Jupiter through special means.

Because the ancients loved to study and explore, they will discover many mysteries.

Because the ancients also wanted to see what was in the universe, they tried their best to explore.

Because Jupiter is not very far from Earth, exploring the universe has always been a human idea.

This is because many planets could be observed at night in ancient times.

Because there may be some ancient documents that are documented about Saturn.

Jupiter was known as the Year Star in ancient China

Jupiter is the fifth-closest planet to the Sun and the largest planet in the solar system, with 79 known moons as of 2019.

In ancient China, Jupiter was called the star of the year, and it was said that it orbited the earth for about 12 years, which is the same as the earth's branch. In the Western Han Dynasty, Sima Qian, the author of the "Historical Records of Tianguanshu", found that the star was cyan from actual observation, which was associated with the "Five Elements" doctrine, and officially named it "Jupiter".

Internal structure. Jupiter has a stony core composed of iron and silicon. Outwardly, it is composed of mixed particulate matter of rock and hydrogen, with no clear boundaries, and is coated outwardly by a layer of liquid metallic hydrogen containing a small amount of helium, mainly hydrogen.

On the inner core, most of the planetary material is concentrated, in the form of liquid hydrogen. The most common form basis on these Jupiters may only exist at 4 billion Pa pressures, and it is this environment inside Jupiter (as is Saturn) where liquid metallic hydrogen is made up of ionized protons and electrons.

Jupiter was known as the Year Star in ancient China

In ancient China, the five planets of the sedan chair state were placed alongside the sun and the moon, and were called the five stars of the sun and the moon, and together they were called the seven yao. respectivelyGlowing Star(Mars), Chenxing (Mercury), Suixing (Jupiter), Taibai (Venus), and Zhenxing (Saturn) are called the five stars, and the five stars are also called the five stars, plus the sun star (sun) and the sun star (moon), collectively called the seven stars.

Qiyao originated in ancient China.

The people's natural worship of the stars can be traced back to the Zhou Dynasty.

It has been widely used since the Han Dynasty. It is recorded in the "Historical Records of Heavenly Officials"."There are five stars in the sky and five elements in the earth. "

1. Venus, because of its strong brightness and silvery-white, was called Star, Dahuo, and Taibai in ancient times. It is the brightest planet in the sky besides the Sun and Moon. "Poetry, Xiaoya, Dadong".

said,"There is Qiming in the east and Chang Gung in the west. "It was the ancients who thought Venus was two stars, dawn.

The one seen in the east is called Qiming, and the one seen in the west at dusk is called Chang Gung.

2. Jupiter is closed, and ancient China called Jupiter the star of the year, taking its orbit around the earth for about 12 years, which is the same as the earth's branch. By the Western Han Dynasty, Sima Qian, the author of "Historical Records of Tianguanshu".

From actual observations, it was found that the star was cyan in color, which was associated with the "Five Elements" theory, and it was officially named "Jupiter".

3. Mercury, known as the star in ancient times, is closest to the sun, and always seems to swing on both sides of the sun, and is no more than 30 degrees away from the sun. In ancient China, the day of the week was divided into 12 days, each of which was about 30 degrees, so Mercury was called the star of the morning.

4. Mars, known as Yingfu in ancient times, was named after its red light and fire. In ancient China.

Take its meaning of "glowing like fire, brightness and position are closed and bent and even confusing people", named "glow", Mars is also known as penalty star, law enforcement.

5. Saturn, the ancient famous town star, Saturn orbits the sky once every twenty-eight years, and enters one of the twenty-eight nights every year, called the year town one night, as if taking turns to sit on the twenty-eight nights, so the name town star.

It is impossible for humans to enter Jupiter.

Inside, the surface of Jupiter is a tornado.

1.Jupiter is the solar system.

One of the largest planets, scientists used to have great hopes for this planet, but when we really got close to this planet, it was discovered that Jupiter was just a gas planet. Its atmosphere is heavier than that of the Earth, and its main components are gaseous and liquid hydrogen. In this gas flow, there will be many instability on the surface of Jupiter.

In such an environment, it is not suitable for human survival.

2.In the universe, most objects are not solid, or do not have a solid surface. For example, Jupiter, humanity's most curious celestial body, is a gas giant.

Jupiter as we see it in space is actually the atmosphere on its surface.

Because the gravity on Jupiter's surface is twice that of Earth, the person will feel heavier first – but he has nothing to step on in Jupiter's atmosphere, so this feeling is not obvious.

3.Unlike Earth, Jupiter is just one large gas that comes together in the shape of a planet. Also, similar to Earth's atmosphere, the gas in Jupiter's atmosphere has a ceiling or top.

The farther you get from the planet, these layers get thinner and thinner until at a certain distance, and the atmosphere becomes an interstellar space.

From Jupiter's surface, Jupiter is just a huge gathering of gas.

4.From a scientific point of view, it would be difficult for a human plane to pass Jupiter. Over time, we will experience difficulty breathing, which also requires us to increase our lung capacity.

Although Jupiter looks like a gas planet, it has a very dense interior and a very high pressure. Liquid metallic hydrogen alone is formed when the gas is compressed, and its pressure is equivalent to 2 million atmospheres on Earth, not to mention the super-pressure in the core of a rock. Currently, no material known to man can withstand this kind of stress.

The above is the answer to the question of whether it is possible for humans to enter Jupiter and what the surface of Jupiter is like.

It is impossible to enter Jupiter, the surface is full of red or white streaks, there are two color swirls, and the material inside will tumble to the surface.

It is unlikely, because Jupiter's magnetic field is very strong, and it is necessary to remove storm obstacles on Jupiter's surface, which human technology has not yet reached. Jupiter's surface has numerous streaks, which are very terrifying storms, with winds capable of reaching 130 to 150 meters per second.

It is possible for humans to enter Jupiter; Jupiter's surface is filled with gas, and most of its structure is masonry. The fraction of the surface can reach more than 100 meters per second.

Jupiter was called Sui Xing, Tai Sui in ancient China. It orbits the sun for 12 years, which coincides with the twelve earthly branches, hence the name. This property makes Jupiter a giant clock in the sky, with the importance of dating and revising the calendar.

Jupiter, Saturn, Uranus, and Neptune are all gas planets, and Jupiter's density is g cm, so they can be called "Jupiter-like", and Jupiter and Saturn are also called "giant planets" because of their huge size.

Features of Jupiter

1. Jupiter's upper atmosphere is composed of about 88-92% hydrogen and about 8-12% helium in volume or gas molecules.

2. Since the mass of the helium atom is four times that of the hydrogen atom, the mass composition of Jupiter will change somewhat: hydrogen and helium account for 75% and 24% of the total mass in the atmosphere, respectively, and the remaining 1% is other elements, including trace amounts of methane, water vapor, ammonia and silicon compounds.

3. In addition, Jupiter also contains trace amounts of carbon, ethane, phosphine, sulfur and other substances. The outermost layer of the atmosphere contains frozen ammonia crystals. Trace amounts of benzene and hydrocarbons have also been detected on Jupiter through infrared and ultraviolet measurements.

Jupiter is also known as the Tai Sui star.

Jupiter is second only to Venus in brightness, and ancient China used it to determine the age of the year, so it was called "Year Star", and the West called Jupiter "Jupiter", that is, the king of the gods in Roman mythology;

Jupiter is also known as the king of the planets, because it is the largest planet in the solar system, both in mass and volume, Jupiter's mass is more than times the mass of the other planets combined, and the volume is more than 1,300 times larger than that of Earth, which is large enough to be king.

Jupiter is like a clock hanging in the sky, and the ancients recorded the sexagenary through its regular movement, and it orbited the sun for 12 years.

Years of Stars.

In ancient China, Jupiter was called the star of the year, and it was said that it orbited the celestial sphere for about 12 years, which is the same as the earth's branch.

In the Western Han Dynasty, Sima Qian, the author of the "Historical Records of Tianguanshu", found that the star was cyan from actual observation, which was associated with the "Five Elements" doctrine, and officially named it "Jupiter".

Jupiter Overview: Jupiter is a giant planet with a mass of one-thousandth the mass of the Sun, but twice the mass of the other planets in the solar system combined. Jupiter's main component is hydrogen, but helium, which accounts for only one-tenth of the molecular quantity, makes up a quarter of the total mass; It may have a rocky core and heavy elements, but no solid surface that can be clearly defined.

Due to its rapid rotation, Jupiter's appearance appears as an oblate sphere. The atmosphere is divided into different zones and zones depending on latitude, and there are turbulence and storms at the junction of each other. The most striking example of this is the Great Red Spot, a huge storm that has not stopped since it was first seen by a telescope in the 17th century.

Jupiter is also surrounded by faint planetary rings and a powerful magnetosphere, including four Galileo moons, discovered in 1610, and 79 moons have been discovered as of December 2019. Ganymede is the largest of them all, and its diameter is larger than that of Mercury in the planet.
