Hegel said: Only when a nation has a group of people looking up at the stars can they have hope. I understand that people who often look up at the stars will not only stare at the scenery in front of them, but their footsteps are always on the road to progress. Any place that cannot be reached by footsteps can reach; wherever eyes cannot be reached by eye, the mind can be reached by mind. Let us look up at the starry sky. The stars in the night sky will light up the long-lost spiritual lamp and the spiritual lamp in our hearts.
The previous article briefly introduced the four major triangles in spring, summer, autumn and winter, and was liked and encouraged by teachers and friends. While the autumn is clear and the starry sky is clear, this article will introduce several relatively regular quadrilateral and pentagonal astrological patterns in the night sky.
2. Spring and autumn quadrilateral
(I) Spring quadrilateral. Spring Quadrilateral is the spring large diamond, also known as the diamond of Virgin, and is a cluster of stars. It consists of four stars: Chang Chenyi (Dog alpha) in Dog Reaper , Five Emperors (Leo β) in Leo , Virgo , Virgo , and Big Arcline (Postrum α) in Pisces . It covers a larger space than Beidou. Finding this huge "diamond" makes it easy to locate the throne, Virgo, Leo and Canine.

, the Great Arctic Star, the Ark of the Shrine and the Five Emperors. In the previous article, I will not say much.
Dog Retriever represents the two dogs Chara and Asterion led by the zodiac (called Chang Chen Si and Chang Chen Yi in Chinese). It is one of the three signs representing dogs, the other two are Dogs and Canis .
[ Changchenyi ] is the brightest star in Dog Reaper, with a magnitude of between 2.84 and 2.98. It is about 110 light years from Earth. In Chinese, Cháng Chén means the imperial guards in the palace. "Book of Jin: Astronomy" records: "The seven stars are always in the north of the emperor's throne. The emperor is with the men of Wu Ben to set up a border."
In October, the sun sets soon we can see them in the western sky. In March, the spring quadrilateral is located slightly east of the middle sky.
(two) Autumn Quadrilateral. Autumn quadrilateral consists of three stars α, β, and γ of Pegasus and α star of Andromeda . In other words, it is a quadrilateral consisting of Pegasus 1, 1, , and Andromeda's 2. Although these four stars are second-class stars and are not so bright, because of their special patterns, they are unique in the autumn starry sky. It is particularly convenient to find other stars with it as the center and the main symbol of the autumn night sky.

[ room 2 ] Pegasus β star is the second brightest star in Pegasus. It is a red giant with a diameter of 95 times larger than the sun, a mass of 3 times that of the sun, and a brightness of 1500 times that of the sun.
【号一个文 】Pegasus γ star, which means the first star that forms the wall, is regarded as "wings" in the West. The quadrilateral is located at the lower left corner of the Pegasus quadrilateral. It is a magnitude of the zodiac zodiac. Its visual magnitude changes between +2.78 and +2.89 in a 3.6-hour period. The distance from the earth is 335 light years, the brightness is 4,000 times that of the sun, the diameter is 4.5 times that of the sun, and the mass is about 7-10 times that of the sun.

In the evening of October, you can see it in the northeast sky, and it is located in the middle of the sky at midnight. It is located in the north of it with a "W" shape of Cinnamon .
3. Spring, autumn and winter pentagons
(I) Spring pentagons. Spring pentagon refers to a pentagon composed of five medium bright stars in Masahisa, like a big kite. These five stars are: ,
, Zhaoyao, 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs and 7 gongs.
【 Arked Star 】The brightest Arked Star in this constellation (the viewed magnitude is -0.05, etc.), looks like a beacon hanging under a kite. The Arctic Star is one of the three brightest stars in the northern sky (the other two are Vega and 5 Car II). Ancient Greek people praised it as "the most beautiful star among all stars" and an orange superstar. It is about 36 light years away from us, with a surface temperature of about 4400 Kelvin , a diameter of about 21 times the diameter of the sun. In spring, there is a saying of "double angle guarding eastward". The so-called "double angle" refers to the big angle star in Masahito and the katsuichi of Virgo. These two stars guard both sides of the eastern sky in spring like two loyal guards. Ancient Greeks imagined the star chart of the constellation Madonna as a ferocious hunter, holding a spear in his right hand and holding his left hand high, wishing to grab the Ursa Major in front of him (the star of the Great Star is located in the awkward position of the hunter).
From February, Madame will slowly rise from the east; in late spring and early summer, Madame is located at the zenith position. In October, Madame is located in the west, and can be seen after the sun sets.
(two) Autumn pentagon. Autumn Pentagon refers to the throne of fairy, which is very eye-catching on autumn nights. Celestial Throne is close to Casino posterior, most of which are immersed in Galaxy , forming a "fan pentagonal" pattern.

(three) Winter pentagon. Winter pentagon refers to the pentagon composed of five bright stars, ι, α, β, θ and Taurus β in . Located in the north of Bisu, it was called "Five Cars" in ancient China. It is said to be the imperial parking lot of Gods in the east, west, south, north and central directions. However, some scholars believe that the five chariots represent the five types of military vehicles in ancient times, namely, military chariots, Guangzhou chariots, Que chariots, Apple chariots, and light chariots.
In the Western constellations, the image of the Imperial Majesty is an excellent driver who drives a four-wheeled carriage.
[ Yufu Seat ι] Five cars and one is the first of the five chariots. Its inherent name is Al Kab, which refers to the person holding the reins, and its traditional name is Hassale. The five cars are one of the orange K-shaped bright giants with an apparent magnitude of +2.69, about 512 light years away from the earth, and the absolute visual magnitude is -3.88, and the brightness in the visible light band is 2900 times that of the sun, the total energy is 5400 times that of the sun, and the diameter is 127 times that of the sun, which is more than half of the distance from the earth to the sun. The mass is about 7 to 8 times that of the sun, not enough to form a supernova.
[ Oshima α] means the second of the five cars, which is the sixth bright star in the day, second only to the Great Arctic and Vega in the northern hemisphere, and is the third bright star in the northern sky. The English name is Capella, which means little goat. The visual magnitude is 0.08, 42.2 light years away from us, car 2 is a big family, composed of 4 stars. Including two bright superstars Capella Aa, Capella Ab and two dull red dwarfs Capella H, Capella L.
Capella Aa, Capella Ab forms binary star system . Since their orbital planes are inclined towards us, there will be no phenomenon of one being blocked by the other, which means covering up the food, so it is called spectroscopic binary stars. The surface temperature of the main star is about 4900K, the radius is about 12 solar radii, and the mass is about 2.7 solar mass , and the luminosity of the entire band is about 79 times that of the sun. companion star temperature is about 5700K, the radius is about 9 solar radii, the mass is about 2.6 solar masses, and the luminosity in the entire band is about 78 times that of the sun. The main star has an approximate magnitude of 0.91, while the companion star has an approximation of 0.76.They are very close, only 0.74 astronomical unit , probably the distance between the sun and Venus. But it rotates very slowly, and it takes 104 days to rotate around each other.
Muka is located in the northwest of Taurus and Orion
Among all the brightest stars, the five-car 2 and North Star are closest. Because it is closer to the North Star, for most observers in the Northern Hemisphere, it is located above the horizon for more than 20 hours in a day. In the area north of Harbin, the five-car 2 will not fall below the horizon and you can see it all year round.
[ β] Five car three is an A2 type white superstar with an apparent magnitude of 1.90, the 41st bright star in the day, about 85 light years from the earth, and the absolute magnitude is 0.6, which is 45 times the sunlight luminance of .
号号号号号号号 is actually a Samsung system. The two brighter stars, βA and B, are both white sub-superstars. The mass and radius of star B are comparable to that of star A. βA and B of the constellation constellation form a joint star. The combined visual magnitude of the two changes in the range +1.85 and +1.93 in the 3.96004-day cycle. At the same time, from the perspective of the earth, one of the stars will partially cover the other every 47.5 hours, so it is called a double star covered. The third star, βC, is a red dwarf, whose visual magnitude is far lower than the brightness that can be seen by the naked eye.
[ Yuhu θ] Five car four, is an joint star system, about 173 light years away from the earth.
[ Taurus β] Five car five, English name El nath, means "boundary", with a magnitude of 1.65, ranking 27th on the bright star table, 150 light years from the earth. Before the 20th century, the five carriages and five were called the γ star of the sign of the sign of the , and now it is changed to Taurus β, which is the second brightest star of Taurus.
