The twelve constellations are in BC.

What is a constellation?

CONSTELLATION, whose Latin name is Constellation, refers to the combination of a group of stars with similar positions projected on the celestial sphere. English is "Constellation", which means "constellation" and "constellation"; Constellations in astrology mean "signs", "signs" and "symbols". Different civilizations and historical periods may divide constellations differently. Most modern constellations evolved from the traditional constellations of ancient Greece, and the International Astronomical Union accurately divided the whole day into 88 constellations.

How many constellations are there? How are constellations divided?

There are 12 constellations in different celestial positions. The twelve constellations are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

The origin of constellations

Western ancient constellations originated in ancient Babylon, one of the four ancient civilizations. It is said that the so-called Zodiac 12 constellation has more than 20 constellation names, and Mesopotamia was born about 5,000 years ago. Since then, the Babylonians have continued to divide the sky into many regions and put forward new constellations. Around 1000 BC, 30 constellations have been proposed. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table. In the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. Connect the main bright stars in the constellation with imaginary lines, imagine them as images of animals and Hu characters, and give them appropriate names in combination with fairy tales. This is the origin of the constellation name. Most of the 48 constellations in Greek mythology live in the northern sky and north and south of the equator.

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.

The seven lodgings of Oriental Dragon are: horn, health, edge, room, heart, tail and dustpan.

The seven nights in South Suzaku are: well, ghost, willow, star, Zhang, wing and bird.

The seven accommodations of Xibaihu are: Kui, Lou, Wei, Chang, Bi, Gou and Shen.

The seven nights in Xuanwu in the north are: fighting, cattle, women, air, danger, houses and walls.

Modern 88 Constellation 1928 The International Astronomical Union officially announced the international 88 Constellation scheme. 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 major regions, namely, the Northern Sky Constellation (5), the Zodiac Constellation (12 constellation near the ecliptic on the celestial sphere), the Zodiac Constellation (10) and the Southern Sky Constellation (-30 ~-90), with a total of 42 constellations. The 88 constellations of the whole day are:

Zodiac (12): Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

Zodiac signs (10): Ophiuchus, Eagle, Unicorn, Sagittarius, Canidae, Serpent, Sextant, Ophiuchus, Orion and Whale.

Southern constellations (42 in total): Centauri, Phoenix, Crane, tán, Picture Frame, Fly, Mountain Case, India, Tian Yan, Flying Fish, Long Ruler, Swordfish, Clock, Rhododendron, Southern Triangle, Compass, Dragonfly, Telescope and Water Snake.

Polaris (19): Pegasus, Cygnus, Scorpio, Andromeda, Pantheon, Auriga, Canis, Foxtra, Little Lion, Perseus, Shepherd, Ursa major, Beiguan, Tmall, Lyra, Dolphin and Triangle (constellation).

Northern Sky Constellation (5): Ursa minor (closest to the north celestial pole), Ursa major, Cassiopeia, Draco and Cepheus.

Extended data

The origin of the twelve constellations:

More than 2000 years ago, the Greek astronomer Hipparchus (BC 190 ~ BC 120) divided the ecliptic into 12 segments, with the spring divided into 0, and every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic) as a palace, subject to the main height of each palace at that time.

Babies born when the earth moves to every bisector (constellation) always have similar characteristics when they grow up, including behavioral characteristics. By connecting these associations (rich imagination and creativity) in series, these constellations are visualized; It also adds the color of myth and becomes an important part of culture (mainly Greek and Roman mythology).

This set of numerology has been developed and circulated for at least five thousand years, represented by these twelve constellations respectively.
