How to divide the constellations

Constellation refers to the stars in the sky. In fact, the stars in the same constellation have no actual relationship with each other, but their projection 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 are divided into Polaris, South Star and Zodiac. The whole day is currently divided into 88 constellations. Constellations are generally named after musical instruments or Greek mythical figures.

1928 The International Astronomical Union officially announced 88 constellations commonly used in the world. At the same time, it is based on the vernal equinox and equator of 1875. According to the different positions of the 88 constellations on the celestial sphere and the appearance of the stars, they are divided into five regions, namely, the Northern Celestial Constellation (5), the Polaris Constellation (40 ~ 90, 19), the Twelve Constellations (12 constellation near the ecliptic on the celestial sphere) and the Zodiac Constellation (19).

The 88 constellations of the whole day are:
