There is an urgent need for a broadcast draft about constellations (don't use constellations, just introduce the real constellations in the sky, understand? )

In order to identify the stars easily, people divided several regions according to their natural distribution in the sky. Different sizes. Each region is called a constellation. Connect the bright stars in the same constellation with lines to form various figures. In shape, they are similar to animals and utensils. There are nearly 6,000 stars visible to the naked eye, each of which can be classified as a unique constellation. Each constellation can be identified by the shape of the bright star inside. 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, such as Orion and Scorpio. The International Astronomical Union divides the sky into 88 official constellations with precise boundaries, so that every star in the sky belongs to a specific constellation. Most of these official constellations are based on the ancient Greek traditional constellations handed down from the Middle Ages. 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. CONSTELLATION is English "Constellation", which means "Constellation" and "Constellation"; The constellation in astrology is "constellation", which means "sign", "sign" and "symbol". There is such a translation in the English-Chinese dictionary: "Zodiac" is the same free translation as the English-Chinese astronomical vocabulary; In Ying Ying's dictionary, it is explained in more detail: "one twentieth of the zodiac", which means "twelve ecliptic divisions". Therefore, the twelve constellations in astronomical calendar and astrology are different in practical sense. If you are not an astrologer, you should compare your date of birth with the actual dates of the twelve constellations in the astronomical calendar to see which constellation you belong to.

Edit the origin of this constellation

Western ancient constellations

Western constellations originated in 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 5000 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 or 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.
