What is a constellation? What constellations are there? How to calculate?

In ancient times, in order to facilitate navigation and observe astronomical phenomena, people connected the scattered stars in the sky through imagination. Half of them were named in ancient times, and the naming method was based on the myths and forms of ancient civilizations (including the myths and epics of Mesopotamia, Babylon, Egypt and Greece). The other half (mostly in the night sky in the southern hemisphere) was named only in modern times, and is often named after navigation instruments. In ancient times, because of different regions, the way to see the starry sky was different! Now the world divides the sky into 88 regions and 88 constellations according to the constellation map. The "constellation" we usually say refers to the "sun constellation"; That is, people on the earth are the center, and at the same time we can see which constellation the sun is in orbit (Greek zodiac: the circle made by animals, also known as the "zodiac"), so we can say what constellation that person is. 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. Babies born when the earth moves to every bisector (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics and personality characteristics. Connect these associations (rich imagination and creativity) in series to make the humanity of these constellations concrete; 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. But these constellations do not represent a certain "star", but can only be regarded as "representative symbols of the same name".

From February 20th to March 20th, Atamas, the legend of the origin of Greek mythology in the twelve constellations, the king of Tiphilia in Aries, married Princess Niepera, and they gave birth to twins. However, the king had an affair with Princess Ginova of Tebe, drove Princess Niepera out of the palace and welcomed Nova as the new princess. When Princess Khynova had a child of her own, she decided to kill the only twin left by her predecessor, Princess Niepera (the elder brother is Prica and the younger sister is Hurley). She bribed the fortune teller to complain to the king: If the children born to the former princess are not sacrificed to Zeus, the gods will be furious and there will be famine this year. When Nipola knew about it, he asked Zeus for help, so Zeus sent the golden ram in the sky to the other side of the sky with his two brothers and sisters. Because the speed was too fast, my sister fell into the sea, and the ram looked back at my sister and guarded my brother, forming today's Aries. Legend of Constellation-Taurus crosses the Behnas River in Mogna, Greece, and King Behnas has a beautiful princess-Herobe. One day, the princess and the maids went to the wild to pick flowers and play. Suddenly, a snow-white cow appeared and looked at Heluobei with gentle eyes. In fact, this cow was changed by Zeus who admired the beauty of the princess. At first, the princess was really surprised, but she went to the tame cow and touched it gently. Because the bull is very clever and docile, the princess climbed onto the bull's back and tried to ride it. Suddenly, Niu Ben ran and finally jumped into the Aegean Sea. The princess clung to the cow and all the creatures in the sea came out to pay tribute to Zeus. The princess finally knew that the cow was the incarnation of Zeus. When she arrived in Crete, she married Zeus, and Zeus, who became a cow, and Princess Shilobe lived a happy life. Constellation legend-Gemini is infatuated with the beautiful Spartan princess Zeus and turns into a swan to approach her. They gave birth to twins-the son of borax and the son of Custer. Both of them are brave and adventurous warriors, and they often make great achievements together. They also have a pair of twin cousins-Iddas and Lincks. One day, four people are going to catch cows. When they caught a lot of cows and prepared to share them equally, greedy Iddas and Lincks took advantage of borax and Caster's surprise and snatched them back. The enraged twins had a big fight, and Iddas shot casto with an arrow. Borax is very sad. He wants to go to heaven with Kaster, but he can't because he has eternal life. His grief touched Zeus, so he set up a constellation for them, living in the kingdom of heaven and the country of death respectively. Constellation legend-Zeus in Cancer and Akmeni, a girl on earth, gave birth to a son, Hercules, and later married and had children with Princess Derby, and lived a happy life. Due to Zeus' curse on Hera, Heracles himself prepared to commit suicide. In order to make him atone, Zeus was appointed king of Jeristos, and he had to go through twelve adventures, the second of which was to subdue the monster Sidorah who lived in the swamp. Sedola is a giant snake with only nine heads, hiding in a cave near the swamp. Hercules threw a torch at it, and the enraged Sedola attacked it with poison gas. Seeing Sedola's painful struggle, the cancer living in the swamp jumped out and bit Hercules' foot. As a result, cancer was shattered and Sedola was subdued. Hera set up cancer in the sky because she was sad about its death. Legend of Constellation-Hercules, son of Zeus and Akmini, Leo, was appointed king of Jeristos, and he had to perform twelve arduous tasks. The first task is to subdue the immortal cannibal lion in Nemesis Valley. The lion only eats livestock and villagers, and everyone is afraid. He was subdued before, but no survivors were seen. Hercules came to Neme Valley and lost his way for many days before he found the trace of the lion. Hercules tried to shoot an arrow, but the lion's skin was too hard to work. The sword also bent, so he made a thick stick from an olive tree and hit the lion hard on the head. At this time, the lion who was not afraid of bows and swords was also afraid of the angry Hercules. Hercules strangled him and was finally repelled by him. To commemorate this lion, the goddess Hera set up a lion constellation in the sky. Constellation legend-Demeter, the Virgo goddess of agriculture, and Zeus the Great gave birth to her daughter Persephone. One day, when Persephone was picking flowers in the wild, a beautiful flower that she had never seen before was in full bloom. Just as she reached for it, the ground suddenly broke into several pieces and fell down. Mother had to swear by Myrtle to look for her missing daughter, looking everywhere. Helius, the sun god who witnessed everything, told Demeter that Hades wanted to marry Persephone and brought her back to the ground. Demeter withered with grief and the earth became barren. Zeus saw that the situation was serious, but he pleaded with Hades. However, when Persephone was leaving, Haides gave her a pomegranate to eat. Persephone was happy to eat four, because she could leave. As a result, she was forced to stay in the underworld for a year and four months. These four months have become the winter when everything is not suitable for farming today. As soon as Persephone returned to earth, it was spring, and Demeter was the embodiment of Virgo. Legend of the origin of Greek mythology in the zodiac-Atamas, the king of Tejela in Aries, married Princess Neville and gave birth to twins. However, the king had an affair with Khynova, Princess Tiber, who kicked her out of the palace and welcomed Nova as the new princess. When Princess Khynova had a child of her own, she decided to kill the only twin left by her predecessor, Princess Niepera (the elder brother is Prica and the younger sister is Hurley). She bribed the fortune teller to complain to the king: If the children born to the former princess are not sacrificed to Zeus, the gods will be furious and there will be famine this year.

These four months have become the winter when everything is not suitable for farming today. As soon as Persephone returned to earth, it was spring, and Demeter was the embodiment of Virgo. Legend of Constellation-Libra This is the Libra used by the goddess of justice, Storez, to judge good and evil for mankind. Astoria has a balance in one hand and a sword in the other. To be fair, I was blindfolded. In the past, God and human beings lived peacefully on the earth. Although God has eternal life, human life is limited. Therefore, the lonely God has to constantly create human beings. But at that time, there were many people fighting and evil deeds were rampant, and the gods returned to heaven after being disappointed with mankind. Only the goddess Storez is reluctant to go back and stay on earth and teach people to be good. Nevertheless, mankind continued to fall, so the war began, and fighting and killing began. Finally, even Storez gave up human beings and returned to heaven. Libra, who loves justice, peace and justice, is on high. Legend of Constellation-Scorpio In ancient Greece, Poseidon's son Orion was a famous fighter, not only a beautiful boy, but also a strong man, so he was quite popular with women. He is also quite proud. He once boasted that there is no better person in the world than me! The goddess Hera was very unhappy when she heard this, so she sent a poisonous Scorpio to catch Orion and exile him to his original place. Scorpio crept up on the unsuspecting Orion and stabbed him in the heel with a poisonous needle. Orion died before he could respond. Because of this feat, there are scorpions in the sky. Even now, as long as Scorpio rises in the east, Orion dares to hide in the western horizon and sink. Constellation legend-Sagittarius once had a race of half-man, half-horse, and it was a savage race with a human upper body and a horse lower body. However, among a group of cruel people, only the son of Cronus, the God of Harvest, is a wise centaur. He not only knows music and divination, but also is a teacher of Hercules. One day, when Hercules clashed with his people, he was chased and fled to Ken's farmhouse. Angry Hercules aimed at the centaur and shot arrows frequently, but he didn't know that his teacher Kennon was among them and shot him in the foot. Because the end of the arrow is covered with immortality, it can't be freed from pain. Prometheus, the giant god, abolished his immortality and let him die peacefully, becoming Sagittarius in the sky. Constellation legend-Capricorn patriarch Paine is the son of Hermes, the messenger of the gods. He looks very strange, with goat horns, hooves and beard. He is a very good musician. Paine is often invited to parties because he can play wonderful music and bring joy to the gods. Once, when he was invited to attend and work for the gods, the monster Tifeng suddenly appeared and fell into chaos. When Tifeng rushed into the party, all the gods fled. Paine also turned into a fish and jumped into the Nile in a hurry. Because of nervousness, only the lower body became a fishtail, while the upper body was like a goat. This is a goat, half a fish and half a sheep. Legend of Constellation-Hesse, the daughter of Shearer, the father of Aquarius gods, is a staff member who serves and pours wine at the banquet of Olympia gods. Since she married another theologian, the position of serving wine has been vacant. Later, Zeus finally took a fancy to a handsome young Trojan prince-Ganymede. The gods also agreed that he should be a sommelier, so Zeus sent messengers to invite him. However, Ganymede loves freedom and is bohemian. He never agrees to Zeus' invitation. Zeus was very angry when he found out. He not only took Ganymede back, but also forced him to be a waiter forever, and the water in the Aquarius became the source of wisdom for the gods. This is the origin of Aquarius. Legend of the constellation-Pisces One day, because of the sunny weather, the gods held a banquet by the river. Music-loving gods happily sang and played musical instruments, and the atmosphere was quite warm. Suddenly there was a shrill cry. This is Fan Jie, a monster with big wings and a hundred snakes under his shoulders. The gods saw something bad and fled everywhere. Zeus became a bird, Apollo became a crow, Hera became a bull, and julius became a goat. All the gods turned into animals and ran away. African jute, the goddess of love and beauty, and Jeros, the god of love, took her son into a fish and fled into the Euphrates River. At that time, they decided to tie their tails together with ribbons and never separate, thus successfully escaping from the monster. In this way, mother and son are connected by their tails and will never be separated. This is the origin of Pisces.
