Understanding of 12 constellation

For the understanding of 12 constellation, 12 constellation is still concerned by many people in our daily life. In fact, many times we can find that people in the same constellation have certain similarities in personality. The following is the understanding of 12 constellation.

12 Constellation Understanding 1 Constellation Introduction: The twelve constellations, namely the zodiac, are the twelve regions described by astrology that the sun passes through the zodiac on the celestial sphere, including Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces, although Ophiuchus also passes through.

After the International Astronomical Union standardized the constellation boundary in 1928, there were 13 constellations on the ecliptic.

Because of precession, the zodiac in 2 1 century no longer conforms to astrology.

Constellation history: In ancient times, in order to identify the direction and observe the astronomical phenomena in navigation, the scattered stars in the sky were connected by imagination, and half of them were named in ancient times, and their naming methods were attached according to the myths and shapes of ancient civilizations. The other half was named only in modern times, often named after navigation instruments. In ancient times, because of different regions, the way of "Lianliankan" was different! 2 1 century, the world unified the constellation map and divided the sky into 88 regions and 88 constellations.

The "constellation" we usually say refers to the "sun constellation"; That is to say, people on the earth are the center, and at the same time, we can see which constellation the sun is in orbit (Greek zodiac: meaning ~ circle made by animals, also known as "zodiac"), so we can say what constellation that person is. In fact, the origin of this constellation is different from that of the West and the East, and the arrangement of the lunar calendar is also different.

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

There are twelve constellations in all. Babies born when the earth moves to every fraction (constellation) will always have some 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.

12 understanding of constellation 2 what are the twelve constellations?

12 constellations are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

In western astrology, the zodiac is synonymous with the direction of the universe. When a person is born, the stars will fall in the position of the zodiac, which shows a person's natural character and talent. The zodiac symbolizes the psychological level and reflects a person's behavior. Therefore, the zodiac is divided into 12 constellation, which is called the zodiac.

Twelve constellations Source:

The well-documented constellations originated in Babylon, and the Babylonians put forward 30 constellations around 1000 BC.

After the culture of the two river basins (Babylon) spread to Greece, ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table. Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations.

After the Middle Ages, the rise of European capitalism needed to expand outward, and the navigation industry was greatly developed. Ships sailing at sea need to navigate at any time. Stars are the best lights. Among the stars, the constellation has a special shape and is the easiest to observe. Therefore, constellations have received extensive attention. When Magellan sailed around the world, he not only used constellation navigation and orientation, but also studied constellations.

1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations, and their names basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12.

And the constellation we usually say is the 12 constellation on the ecliptic. Each of them has some myths and legends about himself.
