What is a constellation?

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. Basically, dividing stars into constellations is a random process. Different civilizations have different constellations made up of different stars-although some constellations made up of more conspicuous stars are roughly the same in different civilizations.

China Ancient Constellation

In order to facilitate research, people divide the starry sky into several regions, which are called constellations. China has long divided the sky into three walls and twenty-eight nights. Historical records and official records are quite detailed. Sanyuan is the three areas around the north celestial pole, namely Ziweiyuan, Taiweiyuan and Tianshiyuan. Twenty-eight branches are located in 28 areas near the ecliptic and the white road, namely, seven branches in the east, seven branches in the south, seven branches in the west and seven branches in the north.

Modern constellation determination

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). All-day 88 constellations.

Astrology also uses images of 12 constellations: Cancer, Aries, Gemini, Aquarius, Virgo, Leo, Taurus, Pisces, Capricorn, Scorpio, Libra and Sagittarius.

In fact, under the guise of 12 constellation, people's personality characteristics are classified (similar to1February).

12 astrology is something introduced from the west, which simply divides people into 12 categories, far less than China's theory of Yin and Yang.

The theory of Yin-Yang and Five Elements is a simple dialectical thought of China in ancient times, and the world was conceived, developed and changed under the impetus of Yin-Yang and Qi. It is considered that the five elements of wood, fire, earth, gold and water are its basic changing relations. The five elements nourish and restrict each other and are in constant movement and change. This theory had a far-reaching impact on later ancient philosophy, such as ancient astronomy, meteorology, chemistry, mathematics, music, medicine, etc., all developed with the help of the theory of Yin-Yang and Five Elements.

Everything in nature includes two opposing aspects of Yin and Yang, and the opposing aspects are unified with each other. Yin and yang, the way of heaven and earth, the discipline of all things, the parents of change, the foundation of life and death. From this, I derived the Eight Diagrams in Zhouyi (sixty-four hexagrams, 384 hexagrams, 1 1520 strategy of Gan Kun * *); The follow-up development of 60-year-old Jiazi, with four pillars and eight characters (according to different regions), can at least produce (60 *12 * 30 *12 * 2 * 4 =) 2,073,600 different results at the same time, so that everyone has a different fate, and the 6 billion human beings on the earth have their own. Compared with the twelve constellations, it is infinite.
