What constellations can you see in the northern hemisphere on winter nights?

The constellations that can be seen all year round in the middle and high latitudes of the northern hemisphere are Ursa Major, Ursa Minor and Hou Xian Constellation.

Relatively speaking, the only bright constellations between 60 north latitude and the north celestial pole are Ursa major, Ursa minor and Cassiopeia, while the brightness of Draco and Cepheus is 2.5 ~ 6 times darker than the above three constellations. But observers always look at the constellation where bright stars are located, so it is generally difficult to observe Draco and Cepheus.

Orion is the center of the winter sky. After nightfall, you can see three bright stars arranged neatly, which is what the folks call "Samsung shining high". There are four bright stars around Samsung that form a rectangle with Samsung. This is Orion. Samsung is Orion's belt. When the three-star line extends to the lower left, you can see Sirius, the brightest star in the whole day. It is the main star of Canis Canis. When it extends from Samsung to the upper right, it is the bright red star Biju V. Taurus is Gemini in the southeast, Cancer in the east and lion head in the east. To the west of Taurus is Aries, and to the north are Perseus and Auriga. To the southwest of Orion is the long and big but very dim constellation Bojiang. The main star Shuiwei No.1 can't be seen until Guangdong. South of Orion are rabbits and pigeons. South is the main star of carina. Below Orion's Samsung, there is a bright spot, which is the Orion nebula. Next to the leftmost part of Samsung is the Horsehead Nebula. The Pleiades cluster in Taurus is an excellent open cluster, consisting of about 500 stars. The screen opens. NASA ... shows Orion and Canis major (including Sirius, the brightest star in the whole day).
