What are the four constellations of Tianjin?

Question 1: What constellations are there in the four seasons? In the starry sky in spring, the most striking thing is the Big Dipper (that is, α, β, γ, δ, ε, ζ, η) hanging high in the northern sky. Because the brightness of the seven stars is relatively high, they are all easy to find. Starting from the Big Dipper, you can find the main bright stars in spring: the two stars (β and α) connecting Doukou, extending to five times the distance between the two stars, you will find the brighter Polaris (α of Ursa minor); Looking southwest along the connecting line of the other two stars δ and γ in Doukou, you can find the bright Xuanyuan XIV (Leo α star). A large arc can be drawn along the curves of several stars (δ, ε, ζ, η) on the barrel handle. If you extend this arc, you can find the bright orange star arcturus (alpha star of Capricorn), continue your southern tour, you can find another bright star Virgo of arcturus (alpha star of Virgo), and then continue your southwest tour, you can find a quadrilateral composed of four small stars, which is corvus corax. This big arc, which starts from the handle of a bucket and ends in corvus corax, is the famous "Big Spring Curve". The triangle consisting of arcturus, Cepheus and Leo β is called the "Spring Triangle". An equilateral quadrilateral consisting of a spring triangle and a star in Canis Canis is called a "spring diamond". The important symbol of the starry sky in summer is the Milky Way, a band of light extending from Dongping line in the north to the southern horizon, and a "summer triangle" consisting of three bright stars on both sides of the Milky Way: Vega (Alpha Lyra), Altair (Alpha Aquila) and Tianjin IV (Alpha Cygnus). The Milky Way in summer is extremely magnificent, but it can only be seen in the wild without light interference. When Vega cruises south along the shore of the Milky Way, she can see a bright red star-Antares (Scorpio α), which forms an S-shaped curve with more than a dozen stars. This is the famous Scorpio in summer, and its tail is immersed in the dense part of the Milky Way. From Altair to the south along the Milky Way, you can find Sagittarius, six of which form the "Southern Dou Six Stars", which is far opposite to the Big Dipper in the northwest sky. The Milky Way in Sagittarius is the widest and brightest. Because this is the direction of the center of the galaxy. The connection between Vega and Altair continues to extend to the southeast, and Capricorn composed of dark stars can be found. Patrol southwest along the connection between Tianjin Sihe and Vega, and you will find Wuxian. In the west of Wuxian, there are seven small stars in a semicircle, which is the beautiful northern crown. The starry sky in autumn "flying horse in the sky, galaxy hanging obliquely" is a symbol of the starry sky in autumn. The starry sky in autumn can start from the "autumn quadrangle" (also known as "flying horse-fairy box") in the direction of the head. This quadrilateral is like a square. When it is overhead, its four sides just represent one direction. The quadrangle in autumn is made up of three bright stars in Pegasus (α, β, γ) and one bright star in Andromeda (α), which is very eye-catching. Extend the east side line of the quadrilateral to the northern sky (that is, from the gamma star of Pegasus to the alpha star of Andromeda), find the Polaris through Cassiopeia, and extend southward along this baseline to find the bright star (β) of Cetacea. This long north-south line is almost at Right ascension. It is convenient to remember and estimate the position of the stars. Extend the western line of the quadrangle to the southern sky (that is, from the beta star of Pegasus to the alpha star), and at the low altitude in the south, you can find the famous bright star in the autumn sky-Beijiao (the alpha star of Pisces), and extend northward along this baseline to find Cepheus. From the northeast corner of the quadrangle in autumn to the northeast along Andromeda, Perseus composed of three rows of stars can be found. To the southeast of the quadrangle in autumn are Pisces and the Great Whale. Wang Xian, Hou Xian, Fairy, Perseus, Pegasus and Whale form a brilliant royal constellation, which is the main constellation in the autumn sky. To the southwest of the autumn quadrangle are Aquarius and Capricorn. There are few bright stars in the autumn sky, but there are many deep-space objects like Andromeda Extragalactic Galaxy (M3 1). The sky is bright in winter, and it is freezing in winter. It's not a pleasant thing to go out and watch the stars at night. However, in all seasons, the starry sky in winter is the most magnificent. Winter is the brightest season of stars all year round, and many constellations are very easy to identify. Of course, the most striking thing is Orion hanging high in the southern sky: the three stars (Orion δ, ε, ζ) sandwiched between the red bright star Betelgeuse (Orion α) and the white bright star Betelgeuse (Orion β) are quite attractive. Looking south and east along Samsung, you can find Sirius (Alpha Canis), the brightest star in the whole day. Due east of Betelgeuse ... >>

Question 2: Find the stars, mainly the positions of constellations. The main constellations in the sky in spring are Ursa major, Ursa minor, Leo, Capricorn, Canis major, Virgo, Raven and Ophiuchus. Summer is a good time to see the stars. Look west after dark, and you will find the constellation Leo. To the east of Leo is Virgo. In the south of the sky, a bright red star shines in the lower sky, which is the main star of Scorpio. It is also a bright star on the ecliptic. The obvious feature of Scorpio is that the distance between three stars is arc-shaped, and Antares is just at the center of the circle. In ancient astronomy in China, Scorpio belongs to Shang star and Orion belongs to Canxing. It just rises and falls, so a poet said, "It is almost as difficult for friends to meet each other as it is for the stars in the morning and evening." To the east of Scorpio is Sagittarius, and the eastern half of Sagittarius has six stars. There is a white band of light, which is the Milky Way. Looking northeast along the Milky Way, you can see Vega and Altair, with two small stars on the left and right. The bright star that forms a triangle with these two bright stars is Tianjin IV, which forms a cross with other stars in Cygnus and is easy to identify. The Big Dipper is in the northwest sky at this time. After finding the shepherd, it is almost at the zenith. It is called the Northern Crown, just like a crown studded with jewels. There are many galaxies here. The starry sky in autumn night is clear and transparent, and it is also a good opportunity to see the stars. On the southwest horizon, Sagittarius has been hanging there obliquely. The ancient book says that "Beidou withers and the south fights obliquely" refers to this. There are cowherd and weaver girl whispering in the western sky. Tianjin No.4 is also the light bulb there, but there is only one lonely bright star in the south. There are two bright stars rising in the northeast corner: Capella (the main star of Auriga) and Bisuwu (the main star of Taurus). There are many princes and nobles in autumn night: fairy king, fairy queen, fairy, Perseus, flying horse and whale. East of the zenith is Pegasus. Andromeda is in the northeast of Pegasus. To the east is Perseus. The big Ling V in Perseus is a famous eclipse variable. Cetaceans have a long-period variable called "Zenger" (those two words can't be typed out). Between Perseus and Cassiopeia, there is a pair of Perseus clusters. Andromeda has a famous big galaxy: Andromeda Nebula. This is a galaxy much larger than the Milky Way, and it is also the closest galaxy to us in the northern half of the day. Although it is very cold in winter, the starry sky is extremely magnificent. Orion is the center of the winter sky. At the latitude of Xiamen, after nightfall, you can see three bright stars arranged neatly. They are the ones who say that "Samsung shines high". There are four bright stars around Samsung to form a rectangle, which is Orion. Samsung is Orion's belt. Samsung's connection wants to extend at the lower left. You can see the brightest star in the whole day: Sirius. It is the main star of Canis Canis. Extending from Samsung to the upper right is the bright red star Bi Su Wu. Next to it is Capella. Taurus is Gemini in the southeast, Cancer in the east and lion head in the east. To the southwest of Orion is a long, big but very dim wave constellation. The main star of the Water Resources Commission, only in Guangdong, I vaguely saw Orion as a rabbit in the south. South is the main star of carina. Below the three stars of Orion, there is a bright spot, the Orion Nebula. Next to the leftmost one of the three stars is the Horsehead Nebula. The Pleiades cluster in Taurus is an excellent open cluster. It consists of about 500 stars. The above article is based on the following time: April 8- 10, July 8-6544.

Question 3: Which star is Tianjin IV? Cygnus α is a typical cygnus α star in pulsating variables, and other pulsating stars include Cassiopeia κ and Orion ε. The brightness of Tianjin IV varies from 1.2 1 to 1.29, and there is no clear dimming period.

It forms a beautiful cross with the other four stars in Cygnus, which is far opposite to the southern cross in the southern sky, so western Europeans call these five stars the northern cross. In fact, this big cross looks more like a swan, and Tianjin IV is on the swan's tail.

I guess no one understands this. Look at this photo. It's next to Lila.

Another is that he forms a right triangle with Altair in Aquila and Vega in Lyra, in which Vega is the vertex, which can be judged.

Please note that they are actually far apart in the sky.

Question 4: How many constellations are the stars in the sky divided into by region?

The ancients in China divided the stars in the sky into four groups:

There are dragons in the east, suzaku in the south, white tigers in the west and Xuanwu in the north.

Each group contains seven "huts", which together are "28 huts".

There is also a "Ziweiyuan"-the Big Dipper.

Each star has a name: Tianjin IV, Beiluo Shimen, Hegu III, Xuanyuan XIV, Weaver Girl, Cowherd and so on.

Second,

Westerners divide the stars in the sky into 88 constellations and name each constellation with ancient Greek fairy tales:

(1) Polaris constellations: Ursa minor, Dragon Constellation, Cepheus, Andromeda, Deer Leopard, Ursa major, Shepherd Constellation, Coronation North, Five Immortals, Lyra, Cygnus, Scorpion, Andromeda, Perseus, Auriga, Tmall Constellation, Little Lion Constellation and Houpai Constellation.

(2) Southern constellations: Cetacea, Bojiang, Orion, Kirin, Canine, Serpent, Grand Earl, Raven, Wolverine, Crown, Temple of Heaven, Crane, Phoenix, Clock, Painting, Sailing, Compass, Southern Pisces and Peacock. Flies, Antarctica, Tian Yan, hydra, mountains, moths, sextant, microscope, telescope, Southern Cross, Southern Triangle, Centauri and India;

Zodiac: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

Three.

Westerners found the stars that can be seen in the southern hemisphere after sailing around the world, so they had the Southern Constellation. China people didn't see it in ancient times, so there was no Southern Constellation.

Question 5: Translation of Chinese and foreign names of common constellations and planetary stars: for example, Tianjin IV-Cygnus α, the brightest star in the northern hemisphere;

Sirius alpha

Arcturus, Booth) Alpha

Vega Lyra) Alpha

Capella auriga (alpha)

Betelgeuse Orion β

Alpha star in the south constellation

Achernar，Eridanus)α

Altair aquila alpha

Betelgeuse Orion α

Aldebaran Taurus) Alpha

The name of Tianjin IV you mentioned is Tianjin IV, which is the alpha of Cygnus.

If it's not enough, I'll add it.

Question 6: There are always many stars in the night sky. How to identify which constellation they belong to? 1. starry sky on a spring night.

The Big Dipper hanging high in the northern night sky is the most familiar star. The Big Dipper is a part of Ursa major. It consists of five bright second-class stars and two third-class stars in the shape of a spoon, just like an ancient vessel for holding wine, hence its name.

The Big Dipper is equivalent to the waist and tail of Ursa major. Four of them make up a bucket spoon, and the other three make up a bucket handle. At dusk in spring, the big dipper of the Big Dipper points to the east.

Connect a straight line between Tian Xuan and Shu Tian at the front of the Big Dipper, extend the distance by five times, and you will meet a bright second-class star, which is the North Star. This is the easiest way to find Polaris. Therefore, Tian Xuan and Shu Tian are also called "finger stars". Because the Big Dipper revolves around the North Star constantly, and its height and position change from time to time, you should practice finding the North Star quickly through the Big Dipper at any time.

The bucket handle part of the Big Dipper is slightly curved. If you stretch out along the arc of the three stars on the bucket handle, you will meet an orange-red bright star, which belongs to Capricorn and is named plantain in Chinese. Capricorn is a big constellation, but it is difficult to identify because of its scattered structure. However, it is not difficult to find it through the Big Dipper.

Continuing along this arc, I met another blue and white star near the ecliptic. The Chinese name of this star is Jiaokou, and its bright and clear brilliance has been impressive since ancient times. Jiaokou is the main star of Virgo, clear but not cold, beautiful but not gorgeous, just like a dignified and delicate girl. In ancient constellation books, Virgo appeared as a goddess.

In the sky to the west of Arcturus II, a white star like 1 is shining brightly. This is the main star of Leo, and its Chinese name is Xuanyuan XIV. Like Kakudji, it belongs to one of the nine navigation planets. Besides Xuanyuan XIV, Leo also includes two second-class stars and four third-class stars, which is an easily recognizable constellation.

In addition to the above, the constellations you can see in the Spring Festival Evening include Cancer, Ophiuchus and Raven. But these constellations are not easy to identify. Among them, Ophiuchus is regarded as a long snake arrangement. When the snakehead rises due south, the snakehead has not completely crossed the eastern horizon.

2. Starry sky in summer night

It is best to learn to recognize the summer constellation from Scorpio, which shines near the southern horizon. Scorpio is a powerful constellation, consisting of 1 burning 1 equal star, 3 second-class stars and 10 third-class stars. It is the most magnificent constellation on the ecliptic.

Scorpio is the most famous of all the constellations. A long string of stars on the lower left constitutes a curly scorpion tail, and on the upper right is a scorpion head composed of several stars, with two poisonous needles on the side of the head. Except for a round waist and a face that looks like a scorpion with claws, it won't make people have a second imagination. I am in the heart of the scorpion with the ancient antares (also known as fire). At night, when you see the bright Scorpio in the southern night sky, it will tell you that the long summer has arrived.

In the summer night sky, the exceptionally bright Milky Way is particularly eye-catching, but the brightest part of the Milky Way is still Scorpio and Sagittarius in the east.

Sagittarius doesn't have such a bright star as 1, but it has two second-class stars and eight third-class stars. Although their arrangement is relatively compact and difficult for beginners to find, Sagittarius is a famous constellation in astronomy.

The six stars from the right side of Sagittarius to the upper end of the bow are arranged in a spoon shape, which is called Nandou Six Stars. Although the six stars in Nandou are not as famous and brilliant as the Big Dipper, they still have the beautiful shape of the seven tails of the Big Dipper.

The Milky Way extends from the east side of Scorpio to the north, across the sky, with a momentum of pounds. On the way to the extension, just in the middle of the eastern horizon, two stars as crystal white as 1 face each other across the milky way. Among them, the bright star on the east bank of the Milky Way is the Altair of Aquila, which is the cowherd in China folklore who expects to meet the Weaver Girl on the seventh day. The higher star on the west bank of the Milky Way is Vega in Lyra, which is beyond the reach of the cowherd and lovesick to the extreme.

Walking up the Milky Way from Aquila, there is a white star of 1 near our heads. This bright star is called Tianjin IV, with bright eyes and white teeth, and it is gorgeous in Cygnus. If you look carefully, Cygnus looks like a big cross, Tianjin IV is at the top of the cross, and the foot of the cross faces the eagle. This cross is called the Northern Cross, which corresponds to the Southern Cross in the southern sky. However, the Northern Cross is not as attractive and famous as the Southern Cross.

If the foot of the cross is regarded as Bai Niao's head and neck, and the crossbar of the cross is regarded as wings, Tianjin IV is the tail of a bird, gathering on the crossbar ... >>

Question 7: What constellations are there in the four seasons starry sky? In the starry sky in spring, the most striking thing is the Big Dipper (i.e. α, β, γ, δ, ε, ζ, η, etc.) hanging high in the northern sky. Because the brightness of the seven stars is relatively high, they are all easy to find. Starting from the Big Dipper, you can find the main bright stars in spring: the two stars (β and α) connecting Doukou, extending to five times the distance between these two stars, you will find the brighter Polaris (α of Ursa minor); Looking southwest along the connecting line of the other two stars δ and γ in Doukou, you can find the bright Xuanyuan XIV (Leo α star).

This big arc, which starts from the handle of a bucket and ends in corvus corax, is the famous "Big Spring Curve". The triangle consisting of arcturus, Cepheus and Leo β is called the "Spring Triangle". An equilateral quadrilateral consisting of a spring triangle and a star in Canis Canis is called a "spring diamond". The important symbol of the starry sky in summer is the Milky Way, a band of light extending from Dongping line in the north to the southern horizon, and a "summer triangle" consisting of three bright stars on both sides of the Milky Way: Vega (Alpha Lyra), Altair (Alpha Aquila) and Tianjin IV (Alpha Cygnus).

Patrol southwest along the connection between Tianjin Sihe and Vega, and you will find Wuxian. In the west of Wuxian, there are seven small stars in a semicircle, which is the beautiful northern crown.

From the northeast corner of the quadrangle in autumn to the northeast along Andromeda, Perseus composed of three rows of stars can be found. To the southeast of the quadrangle in autumn are Pisces and the Great Whale. Wang Xian, Hou Xian, Fairy, Perseus, Pegasus and Whale form a brilliant royal constellation, which is the main constellation in the autumn sky. To the southwest of the autumn quadrangle are Aquarius and Capricorn. There are few bright stars in the autumn sky, but there are many deep-space objects like Andromeda Extragalactic Galaxy (M3 1). The sky is bright in winter, and it is freezing in winter. It is not a pleasant thing to sit up and look at the stars. However, in all seasons, the starry sky in winter is the most magnificent. Winter is the brightest season of stars all year round, and many constellations are very easy to identify. Of course, the most striking thing is Orion hanging high in the southern sky: the three stars (Orion δ, ε, ζ) sandwiched between the red bright star Betelgeuse (Orion α) and the white bright star Betelgeuse (Orion β) are quite attractive.
