What constellations are there in winter?

Imperial constellation

One of the northern constellations. Center position: 6: 00 right ascension, 42 right declination. The area is about 658 square degrees. Located between Perseus, Taurus, Gemini and other constellations, half of them are immersed in the Milky Way. The visual magnitude of 102 stars in the constellation is greater than 6, and the brightness of 10 stars is greater than 4.

Carving seat

1752, French astronomer Llakaj described a constellation to fill the gap in the southern hemisphere. From 175 1 to 1752, Llakaj delineated this constellation when passing through the Cape of Good Hope. At first, it was named "the sculptor's file", and later it was renamed "the carving tool". Because the sculpture pedestal was a southern hemisphere constellation established only in17th century, there was no myth related to it before17th century.

Lubao

The leopard is located in the northern part of the celestial sphere. It is surrounded by bears, fairy kings, dragons, bears, Tmall, Yufu and Perseus. It is a big "tall and thin" constellation, but it is darker than 4 stars. Generally, residents in the area south of 7 degrees south latitude can't see this constellation.

Cancer constellation

Cancer is located to the west of Leo and to the north of snakehead. It is the darkest of the twelve constellations. The brightest star in the constellation is only 93.8m, and you can't see the shape of a crab at all. This may be because Hercules had already hit it with a stick. That's right, it still clings to the long snake and goes along with it!

Sirius

One of the southern constellations. The center position is 6: 40 right ascension and -22 declination. The area is about 380 square degrees. Located in the southeast of Orion, between Scorpio and tail constellation. There are 122 stars in the constellation whose visual magnitude is greater than 6, of which 18 stars are greater than 4.

Canine constellation

A constellation in the dog constellation. Located in the eastern part of Orion, between Gemini and Unicorn, on the edge of the Milky Way. This constellation has 1 bright star and is named "Nanhesan". Nanhesan, Betelgeuse and Sirius in the northeast corner of Orion form an equilateral triangle, which is called the "winter triangle" and is very eye-catching in winter nights.

Ship base

Ptolemy said that the tailstock, the vela and the carina are the same constellation (excluding the compass), which is called Argonavis. /kloc-In the 8th century, astronomers thought that the Southern Constellation occupied too much space, so they took it apart. The ship to the south is Argo. In the story, Jason took fifty people aboard Argo to Korcz in the Black Sea to find golden fleece.

swordfish

Located in the southwest of Carina, the constellation Swordfish contains a famous large magellanic cloud. It was discovered by Portuguese navigator Magellan when he sailed around the world to South America in 1520.

In fact, this "Large Magellanic Cloud" is an extragalactic galaxy and a companion galaxy of our Milky Way, with a diameter of 50,000 light years and a distance of160,000 light years.

Bojiangzuo

One of the southern constellations. The constellation with the largest span between north and south. Starting near the southern tip of Orion, it winds between Taurus, Pisces and Scorpio until the southern sky is next to Aquarius. It is one of the main southern constellations in the northern hemisphere on winter nights. The center position is: 3: 50 right ascension, declination-18. The area is about 1 138 square degrees. Between Pisces and Orion, it extends southward from the equator to about-60 declination. Most of the stars in the whole constellation are dark, and only one head and one tail are prominent. The bright star at the southernmost tip of the Bojiang constellation is Water Commission I, which can only be seen in the south of China.

Gemini

Extending the connecting line between Orion's beta star and alpha star to the northeast, we can meet two bright stars which are not far apart, among which the brighter one is Gemini's beta star with brightness of 1. 14, etc. The dimmer star is Alpha Gemini with a brightness of 1.97. A series of stars τ, ε, μ starting from α star are almost parallel to another series of stars τ, ζ, γ starting from β star, and are imagined as two friendly brothers-Caster and Polox Polokus.
