1928 divide the whole sky into several constellation areas? 1928, in order to meet the needs of astronomical research, the meeting clearly divided the whole sky into 88 constellation areas. 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).

Most modern constellations evolved from the traditional constellations of ancient Greece, and the International Astronomical Union accurately divided the whole day into 88 constellations. Let every star in the sky belong to a specific constellation. Constellations play an important role in astronomy; Astrology also uses the image of the zodiac, but it does not use real scientific methods. Astrology is generally regarded as pseudoscience. In fact, in ancient times, technology was not as developed as it is now (except Maya, regardless of the Mayan civilization that cannot be cracked at present). What they did was watch the wind, rain and stars every day. After thousands of years of historical precipitation, the laws of the stars in the sky are summarized. (Not most, but at least a few), some people in the west began to summarize the constellations corresponding to the zodiac and make fairy tales for them.

China is no exception. At that time, our prophet discovered 28 stars through naked eye observation and summary, plus some myths and legends and admiration for nature. Similarly, it is also a collocation arrangement of positions and myths and legends in the sky.

In modern times, with scientific instruments, this guy began to find too many stars outside the universe. 1 is followed by countless zeros. Then, the stars we can observe on the earth began to be classified again. Finally, 1928, the International Astronomical Union divided the sky into 88 constellation regions by a show of hands in order to facilitate everyone's study and unify the names and knowledge points.

Great, what bull star, purple star, Sirius, Andromeda and Ursa major are all carved and named according to international unified standards.
