Do the constellations in the sky change depending on the season?

Yes!. According to the spring, summer, autumn and winter, "the bucket handle refers to the east, and the world is spring; The bucket handle refers to the south, and the world is summer; The bucket handle refers to the west, and the world is autumn; The north finger of the bucket handle, the world is winter. This is the conclusion that the ancients came to by observing the position of the handle of the Big Dipper in the sky.

As the Earth turns from west to east, one can see the rising and setting of stars, a phenomenon known as the sun's apparent motion of the star. Due to the constant rotation of the earth, we see different constellations at the same time and place every day, and the time when the same constellation appears in the same place is also different.

back. Because in the ancient tomb of Puyang, Henan Province, we have excavated a tomb that is a leader in ancient times, so in this tomb, there is a dragon and a tiger made of clam shells, which are listed on his left and right. And under this human bone, that is, under his feet, there is also a shape composed of the bones of his legs.

Then after the research of experts, this dragon is not an ordinary dragon, but refers to the constellation in the sky. In other words, the shape of the star we saw in the southern sky in the summer was already considered a dragon in ancient China more than 7,000 years ago. On winter nights, it is the starry sky in the southern sky, and we will see a white tiger, this white tiger and this dragon are all human imagination.

This constellation is called the Bear Major, and we Chinese have known these seven stars for a long time. This place has a bucket-shaped seven stars, and we call it Beidou. Everyone knows Beidou, so with the two stars in the middle of Beidou, we can connect and find the North Star.

Therefore, Beidou plays a very important role in the process of recognizing stars. But such a constellation is called Beidou in China, and in foreign countries, it is imagined as a big bear, that is, in the shape of a bear.

Due to the rotational motion and the orbital motion of the earth, the apparent position of the celestial bodies on the celestial sphere is subject to daily and annual changes. The orientation and path of the infestation horizon of the constellations will vary from place to place over time, but the shape of the constellations and the relative positions between them remain the same. Most of our country is in the middle latitude of the Northern Hemisphere, and the following are common constellations in the middle latitude of the Northern Hemisphere.

The main constellations of the spring sky are Ursa Major, Ursa Minor, Leo, Shepherd, and Virgo. The main constellations of the summer starry sky are Lyra, Aquila, Cygnus, Scorpio, Sagittarius, and other constellations. The main constellations of the autumn starry sky are Pegasus, Andromeda, Perseus, Cassiopeia, and Cassiopeia.

The main constellations of the winter sky are Orion, Canis Major, Canis Minor, Taurus, Twin Horns, and Auriga. Finally, add the four seasons star recognition song tips as a reference: 1. Spring starry sky:

The spring breeze sends warmth to learn to recognize the stars, the Beidou high hanging handle points to the east, and the two stars at the mouth of the bucket point to the North Pole, and the direction of the North Pole is clear. The lion lies in the spring night sky, the star of Xuanyuan 14 is of the first rank, the shepherd's big horn is along the handle, and the starlight illuminates the voyage. Second, the summer starry sky The south of the bucket handle refers to the summer night, and the Scorpio men and horses are close to each other.

Looking north along the Milky Way, the Aquila Lyra is lined up. The swan flies crookedly, and the cowherd and weaver girl are blue and white. The Antares red star shines on the Nandou, and the starry sky on a summer night is remembered.

3. Autumn starry sky: The Beidou is on the horizon in the autumn night, the fairy queen rises in the sky, the word fairy refers to the northeast, and the Pegasus volleys the quadrilateral. The constellation of the Immortals shines on the night sky, and the five stars of Daling will change The south sky is silent and bright, and there are few stars, and the north falls on the old chaotic master gate Race Lights.

Fourth, the winter starry sky: the three stars shine into the cold winter, the Pleiades are bright and shining, the golden bull bows its head to the hunters, and the stars are brilliant and bright. Yufu five-star pentagonal, kite flying on the Tianhe.

The stars recognize the constellation in the winter night, and Sirius is the brightest star in the whole day.

The most representative constellation in the winter sky is Orion; Playing Dark Xu Naze B;

The reason for this is because Orion has 2 stars of 1st magnitude, 5 stars of 2nd magnitude, and 2 stars of 3rd magnitude, arranged in a relatively regular shape, and is one of the most prominent constellations throughout the day.

The brightest star in the constellation Orion is the star, which is equal in apparent magnitude and ranks seventh among the bright stars throughout the day, with an absolute magnitude of equal and a surface temperature of 12,000 Ke. Orion Star, it is the ninth brightest star in the whole day, Latin is betelgeuse, the brightness varies between the equal and the equal, the brightness change cycle is 5 and a half years, it is an irregular variable star. At eight o'clock in the evening at the end of January and the beginning of February every year, the δ and three stars in the constellation Orion are hanging high in the southern sky, so there is a Chinese proverb "Three stars are in the south, and the New Year will be celebrated".

There are two kinds of movement in the position of the constellations in the sky: the first is due to the rotation of the earth from west to east on its axis, that is, the rotation of the earth, which allows us to see the stars coming out of the east, slowly skimming the sky, and then setting in the west, just like the movement of the sun that we see every day. The second is that because the Earth revolves around the Sun, each star rises from below the horizon about four minutes earlier each day than the previous day, so that the position of the constellation gradually shifts westward at the same time every night throughout the year.

For example, the constellation Orion rises in the east at dusk in early December, and after 3 months, at dusk, the constellation of Orion is already twinkling in the southern sky. By the end of spring, the constellation Orion had set in the west at the same time as the Sun.
