How do constellations help us understand the universe?

Constellations are celestial regions that are considered to be divided on the celestial sphere. It imagines the close celestial bodies in a sky area, so that it is easy to record the distribution of stars in the sky.

For beginners, it is easier to find the celestial body you are looking for through the constellation.

Using constellations, we can transform more abstract latitude and longitude into more specific images, and it is easier to determine the approximate position.

However, I want to emphasize that constellations are artificially divided sky areas and have no influence on the physical properties of celestial bodies. Therefore, the examples given by the landlord are not rigorous (I can't give many examples, and the study of the frontiers of astronomy by constellations can also make readers determine the role of regions more intuitively).
