I want to know information about Uranus.

Update 1: (in English)

Venus is the seventh farthest planet from the sun and the third largest planet in the solar system (in terms of diameter). Uranus is larger in diameter than Neptune, but smaller in mass. Orbit: 2870990000 km from the sun (19.2 18 AU). Diameter: 5 1, 1 18 km (equatorial diameter). Mass: 8.683E25kg. I'm sorry to avoid mispronouncing. It should be pronounced "YOOR a nus". Picture reference: hcc.earth.sinica.edu/earth/star/chinese/nineplas//sound instead of "Your anus" or "Piss on us". Uranus is the god in ancient Greek legend, the earliest god. He is also Cronus (Cronus

Saturn), Cyclopes and Titan (Tit, the ancestor of the Olympian gods), and his wife is Gaia, the mother of the earth. Uranus is the first planet discovered in modern times, which was discovered by William Herschel when he searched the sky with a telescope system in March 178 1. In fact, Uranus has been observed many times before, but it has been ignored as an ordinary star (the earliest observation record was classified as 34 Taurus by John F. Lhostis and john flamsteed in 1960). Hershey named the planet he discovered "Geium Sidus" to commemorate his patron, a little-known (American) King Gee iii； of England; Others call this planet "Herschel". As for the name "Uranus", it was first put forward by Baud in order to be consistent with the naming of other planets according to classical mythology, but the name "Uranus" was not widely used until after 1850. The only spaceship that has visited Uranus is Voyager 2, which passed by on1986 65438+1October 24th. Image reference: HCC. Most planets in earth.sinica.edu/earth/star/Chinese/nineplas/thumb/Uranus's BT solar system rotate at an angle almost perpendicular to the ecliptic plane, but Uranus' axis of rotation runs at an angle parallel to the ecliptic plane. When Voyager 2 passed Uranus, the south pole of Uranus almost pointed to the sun. This phenomenon leads to a strange phenomenon. Uranus will receive more solar energy in the polar regions than in the equatorial regions, but the equatorial temperature of Uranus is still higher than that in the polar regions. The mechanism behind this is still unknown. In fact, about "which pole of Uranus is the North Pole?" The debate is still going on. Its axis of rotation is either a little more than 90 degrees and then rotates forward, or a little less than 90 degrees and then reverses. The problem is that you need to draw a dividing line "somewhere", because whether it really rotates in the opposite direction like Venus (not in the positive direction of inclination 180 degrees) is still controversial. Venus is basically composed of rocks and different kinds of ice, with only about 15% hydrogen and a little helium (compared with Jupiter and Saturn, it is mainly composed of hydrogen). Uranus (and Neptune) is similar to the cores of Jupiter and Saturn in many ways, with a large amount of liquid metal hydrogen removed. This means that Uranus, like Jupiter and Saturn, has no core of rock material, but its material still shows more or less uniform distribution. Uranus' atmosphere contains about 83% hydrogen, 15% helium and 2% methane. Image reference: HCC. Earth.sinica.edu/Earth/Star/Chinese/Nineplas/Thumb/Uranus binary stars, but they are very dim, and can only be seen in Voyager 2 photo after the basic image is enhanced (right). Recently, larger and more obvious stripes have been found from the observation of Hubble Space Telescope (HST). Uranus is no longer the boring planet Voyager saw at that time! He can now clearly show the appearance of different seasons, because the solar system is directly directed at the low latitude area of Uranus, which may lead to more obvious seasonal effects of day and night. By 2007, the sun will be directly on the equator of Uranus. Neptune's blue surface is the result of absorbing infrared light by methane contained in the atmosphere. Its surface may also have ribbons of different colors like Jupiter, but it is covered by the surface. Image reference: HCC. Earth.sinica.edu/earth/star/Chinese/nineplas/thumb/9 Ring Like other gaseous planets, Uranus also has rings, which are as dark as Jupiter's rings, and its rings are also like Saturn's rings, which are mostly caused by large particles (the diameter can be as large as 10 m) and fine dust. At present, there are 1 1 rings in Uranus, each of which is very dark, and the brightest one is called ε ring. Uranus is also the earliest discovered ring after Saturn's ring. The importance of this idea is that we can now know that the "ring" is actually a universal feature of the planet, not a unique structure of Saturn. Voyager 2 discovered 10 small satellites of Uranus, plus five large satellites that we already know. There seem to be several smaller satellites in Uranus' ring. There is something strange about Uranus' magnetic field, which is not centered on Uranus' center. The magnetic field is tilted about 60 degrees relative to the rotation axis, which may be caused by the relative movement inside Uranus' shallow layer. Sometimes, only on a clear night can you barely see the star with the naked eye. If you use binoculars, it is easy to see a bright spot (you must know the correct observation location), and you can see a small disk with small astronomical glasses. There are several websites that show the current position of Uranus (and other planets) in the sky. Some astronomical programs (such as starry night) can describe more detailed data and star maps, so you can make more use of them. Uranus' satellite Uranus has 20 named satellites plus a recently discovered satellite that has not been officially named, so Uranus has the most well-known satellite among all the satellites of many planets. Unlike other stars in the solar system named after classical myths, Uranus' moons are all named after Shakespeare's works and the Pope. Image reference: HCC. These satellites in Earth.sinica.edu/Earth/Star/Chinese/Nineplas/Thumb/Urasats have formed three different categories: 1 1 the smaller and darker inner satellite discovered by Voyager 2; Five relatively large satellites (right); A new discovery is far away. Most of the satellites are in an approximately circular orbit, and the orbital plane is the equatorial plane of Uranus (so it has a great angle with the ecliptic plane), while the orbits of the four outer satellites are all elliptical.

Uranus is one of the eight planets in the solar system. It ranks seventh outside Saturn and Neptune, and its color is gray-blue. It is a gas giant planet. Uranus is the third largest planet in the solar system; But if calculated by mass, it is lighter than Neptune, ranking fourth. Uranus was named after Uranus, the god in Greek mythology. [Editor] Physical properties [Editor] Composition Uranus is mainly composed of rocks and water-ice substances with different compositions, and its main element is hydrogen (83%), followed by helium (15%). In many ways, Uranus (and Neptune) is different from Jupiter and Saturn, which are mostly composed of gaseous hydrogen. Its nature is closer to the core of Jupiter and Saturn, and there is no huge liquid gas surface surrounded by near-earth planets (mainly formed by gravity liquefaction of metallic hydrogen compounds). Uranus has no cores like Saturn and Jupiter, and its metal composition is distributed in the whole crust in a relatively uniform state. Directly observed by naked eyes, the surface of Uranus appears ocean blue, which is because its methane atmosphere absorbs most of the red spectrum. [Editor] Ocean on Uranus According to the detection results of Voyager 2, scientists speculate that there may be a liquid ocean with a depth of 10000 km and a temperature of 6650 degrees Celsius on Uranus, which is composed of water, silicon, magnesium, nitrogen-containing molecules, hydrocarbons and ionized substances. Due to the huge and heavy atmospheric pressure on Uranus, the molecules are close together, which makes this high-temperature ocean unable to boil and evaporate. On the other hand, it is precisely because of the high temperature of the ocean that it just prevents the high-pressure atmosphere from pressing the ocean into a solid state. The ocean extends from the high temperature core of Uranus (up to 6650 degrees Celsius) to the bottom of the atmosphere, covering the whole of Uranus. It must be emphasized that this kind of ocean is completely different from our understanding of the ocean on earth. However, in recent years there has been a view that there is no such ocean on Uranus. What is the truth? I'm afraid we have to wait for further observation, or hope that the National Aeronautics and Space Administration (NASA) will implement the preliminary plan of "New Horizon 2" and send an unmanned exploration ship to visit Uranus again. [Editor] The angle between the polar axis of Uranus and the ecliptic plane is very large, about 98 degrees. This planet is equivalent to "lying down" and rotating, which is very unusual compared with other planets in the solar system. Astronomers speculate that it may be because Uranus was hit off-center by a huge asteroid at the early stage of its formation, so that the polar axis was "knocked down" and appeared in the present situation. [Editor] Uranus was discovered by accident. 1781March13rd, British astronomer William Herschel happened to find a light green star in Gemini while observing the starry sky with a self-made reflective telescope. After several days of observation, he thought it must be a celestial body in the solar system, maybe a comet, so he submitted a paper entitled "Report of Comet" to the Royal Society. 1783, French scientist Laplace confirmed that Herschel had discovered a planet. To this end, William Herschel was awarded the Copley Medal by the Royal Society. [Editor] Satellite main entry: Uranus' satellites currently have 27 natural satellites. The first and second satellites (Titan and oberon) are William? Herschel discovered it in1March 787 13, and the other two Ariel and Umber Rieul were discovered by William in 185 1 year. Wrathall found it. At 1852, William? John Herschel's son? Herschel named these four satellites. 1948, Gerard P. Kupr discovered the fifth satellite Miranda1986 65438+10. In October, Voyager 2 flew over Uranus. Later, when studying the photos, we found Perdita and 10 small satellites. Later, the use of ground telescopes also confirmed the existence of these satellites. Unlike the satellites of other planets, all the satellites of Uranus are named after the plays of English poets Shakespeare and Pope.

However, the temperature in the equatorial region is still higher than that in the polar region, and the mechanism behind it is still unclear. In fact, whether it is the South Pole or the North Pole is still controversial! You can say that Uranus rotates clockwise like most planets, but its axis is slightly tilted by more than 90; Or its axis is inclined slightly less than 90 degrees but in the opposite direction. A similar controversy also occurred on Venus. Some people think that Venus' rotation is not reversed, but its rotation axis is tilted by nearly 180. Uranus is mainly composed of rocks and all kinds of ice. Hydrogen accounts for only 65,438+05%, and helium is a small amount, which is very different from Jupiter and Saturn. Uranus and Neptune are very similar to the core of Jupiter or Saturn after removing the thick liquid metal hydrogen shell. Uranus rocks are not concentrated in the core like Jupiter and Saturn, but are evenly distributed throughout the body. Uranus' atmosphere contains 83% hydrogen, 15% helium and 2% methane. Like other gas planets, Uranus has a high-speed wind belt, but it is very blurred. The image of Voyager 2 must be enhanced to see it (right). The latest Hubble Space Telescope image (left) shows larger and more wind stripes, while other Hubble observations show more activity. Uranus is not as monotonous and peaceful as navigator's eyes. This difference is obviously due to the change of seasons. At present, the sun is at the low latitude of Uranus, which may lead to more obvious weather changes at night. By 2007, the sun will be directly at the equator. Uranus' blue appearance is caused by methane in the upper atmosphere absorbing red light. The colorful wind belt similar to Jupiter may still exist, but it can't be seen because it is covered with methane. Like other gas planets, Uranus has rings, which are as dark as Jupiter's rings, but more like Saturn's rings, surrounded by objects of similar size into rings with the widest width of 10 meters, and some tiny dust. At present, there are 1 1 rings, all of which are dim, and the brightest one is ε ring. Uranus ring is the first discovered planetary ring except Saturn ring, which makes us know that rings are not unique to Saturn, but the normal state of the planet. In addition to the five previously known large satellites, Voyager 2 also discovered 10 small satellites. It seems that there are more tiny orbiting satellites in Uranus' ring. Uranus' magnetic field is very strange. Its magnetic core is not in the geographical core, and the inclination angle between the magnetic axis and the rotation axis is as high as 60, which may be caused by its shallow internal movement. On a very dark and sunny night, Uranus is sometimes almost invisible to the naked eye; If you know its position in advance, you can easily see it with binoculars; A small sphere can be seen with a small astronomical telescope.

Lkcss.edu/eca/astronomy_club/Ourspace/2solarsystem/uranus Uranus is also very big, four times the diameter of the earth. It is composed of extremely cold methane plastids, so its density is also very low. Observed through a telescope, its surface also has zones and stripes similar to Jupiter. Uranus has a different feature from the other eight planets, that is, the angle between its axis of rotation and its axis of rotation is about 98 degrees, just like a horizontally rotating gyro, so the sun will shine directly at the North Pole at one time of the year and at the South Pole at another time. Uranus also has a halo above the equator, but it is not as bright as Saturn's.

The most special thing about Uranus is that its axis of rotation is inclined at 98 degrees, and it lies almost horizontally on the orbital plane. If we are in Uranus, we will find that Uranus faces the sun for half a Uranus year (42 Earth years), and then it is night for half a Uranus year. Uranus was discovered by astronomer Hustler in 178 1 year. Structure Uranus, like other woody planets, is mainly composed of hydrogen and helium, but its atmosphere and interior are rich in methane. The outermost layer of Uranus is an atmosphere composed of hydrogen, helium and methane; Below the atmosphere is an inner layer composed of ice, methane and ammonia; The center is a core made of rocks. 2007-06-02 16:54:24 Supplement: There are 2/KLOC-0 satellites in the satellite and Uranus, the largest of which is Tianwei III, but it is not obvious (the highest apparent magnitude is only 14, etc.). ), so the satellites of Uranus can only be seen with large telescopes and space telescopes. Up to now, there are 1 1 rings of Uranus that have been discovered. Uranus' halo is not obvious. In the hundred years after Uranus was discovered, no one knew about the existence of Uranus rings. It was not until Voyager passed Uranus in 1986 that it was discovered that the halo was made of rocks. Observing Uranus Uranus is only 6 at its brightest, which is the minimum visible to the naked eye, so you need a telescope to see it clearly. It's hard to see a star hunter unless you consider yourself an expert. As of 2009, Uranus will be in Aquarius forever. 2007-06-02 16:54:45 supplement: diameter (earth = 1) 4.0 mass (earth = 1) 14.5 volume (earth = 1) 63 density (.
