From now on: 747 1 constellation refers to the combination of stars in the sky. In the three-dimensional universe, these stars are not actually related to each other, but their positions on the celestial sphere are similar. Since ancient times, people have been interested in the arrangement and shape of stars, and naturally linked some stars with similar positions to form constellations.

Constellations play an important role in astronomy; Astrology also uses images of the zodiac 12, but astronomers regard astrology as pseudoscience without using real scientific methods.
