Is the constellation 12 related to the constellations in the sky?

Let's put it this way: we project all the observable stars onto an imaginary sphere with the earth as the center. This sphere is called the celestial sphere.

For example, Gemini, the most easily noticed constellation in Gemini, consists of Beihe II and Beihe III. Beihe II is actually two white stars that are very close to each other and surround each other. This phenomenon is called "binary star system" in astronomy.

Used to describe the phenomenon that two stars surround each other because of similar gravity. Beihe San is more orange than his brother.

Another example is Leo. People born in the lion month are usually generous, and so are Leo in the sky.

Leo is located at the intersection of Cancer in the west and Virgo in the east. In the northern hemisphere sky, you will see it in late winter and early spring. The most recognizable feature is its mane. In the sky, it is more like a concave question mark or a huge sickle.

If you want to find your own constellation, I suggest you find a star map on the Internet, because there is an error between the time on the constellation and the exact time when the constellation appears, and the stars represented by some constellations in the sky are extremely difficult to be found by the naked eye because of the weather or other reasons, so I suggest you use the Internet to understand your constellation more easily and accurately.
