Scorpio star position

. Scorpio symbol:? Center position: right ascension 16: 40, declination -36 degrees. Summer appears in the southern sky, and the scorpion's tail points to the southeast, between the snake head, Sagittarius and Libra. Alpha star (Antares) is a red star with a magnitude of 1. The open clusters M6 and M7 are visible to the naked eye, and 22 stars in the constellation are brighter than 4 stars.

At eight or nine o'clock in the summer evening, there is a bright star in the south, which is not very high from the horizon. It is Scorpio Alpha (Antares).

Scorpio is the most conspicuous constellation in summer. There are many bright stars in it, and there are more than 20 brighter than 4m. Scorpio is big and bright, with many stars, which can be said to be the representative of the summer night constellation. In addition, it is also a zodiac, so it is particularly eye-catching. However, Scorpio only occupies a short range of 7 on the ecliptic, which is the shortest ecliptic among the twelve constellations.

Scorpio is immersed in the vast galaxy from alpha star to long scorpion tail. Alpha is located in the scorpion's chest, so the west calls it "the heart of Scorpio". Interestingly, in ancient China, the alpha star of Scorpio was placed in the center of 28 nights, which was called "Antares". You see, astronomers in the East and the West happen to coincide.

M7 open cluster M7 is one of the most famous open clusters in the sky. This cluster has many bright blue stars. At night, we can see it from the tail of Scorpio with the naked eye. M7 is about 1000 light years away from us, and consists of about1000 stars, with an age of about 200 million years and a size of about 25 light years.

In ancient Persia, antares, the alpha star of Scorpio, was regarded as one of the four pillars to protect the celestial sphere. The other three pillars were Beiluoshimen, the alpha star of Pisces, Xuanyuan, the alpha star of Leo, and Bisuwu, the alpha star of Taurus.

Antares

In ancient astronomy in China, the three stars in Scorpio are called Shang Xing and the three stars in Orion's belt are called Laonian Xing. Scorpio and Orion are the most prominent constellations in summer and winter respectively. They just rise and fall, never meet, and can't appear in the sky at the same time. Therefore, Du Fu has a poem: "When friends meet, it is as difficult as the stars in the morning and evening." (Eight Guards for Chu Shi).

Edit this constellation myth

Legend 1

Helius's son Phaeton was born handsome, so he felt conceited. His attitude is always arrogant and rude, and his strong personality often makes him unintentionally offend many people.

One day, a man told Phaeton, "You are not the son of the sun god!" " "After laughing, he and roared off. How can the powerful Phaeton swallow this tone? So he asked his mother, "Am I Helius's son?" However, no matter how many times his mother assured him that he was really born in Helius, Phaeton still didn't believe his mother, so he said, "The man who made fun of you is Zeus' son, and his position is very high. If you still don't believe me, ask Helius himself! "

Helius listened to his son's question and said with a smile, "Don't listen to their nonsense, of course you are my son!" " "Phaeton still insist on not believing. In fact, of course he knows that the sun god never lies, but he has another purpose-to drive his father's solar car to prove that he is Helius's son. " How can this work? "Helius is afraid that the sun is the master of all things, and he will be miserable if he is not careful, but he can't beat Phaeton. Helius is explaining how to drive a solar car on a specific track. Phaeton was so proud that he jumped on the bus and galloped away at will.

Of course, the result was tragic. People, animals and plants on the ground are either dying of heat or freezing to death. Time has passed, and it is dark and full of complaints. In order to stop Phaeton, the gods released a scorpion from Hera and bit Phaeton's ankle. Zeus hit Phaeton with terrible lightning, only to see him fall to the ground with a scream and die.

Peace has been restored to the world. In memory of scorpions killed by lightning, this constellation was named "Scorpio".

Legend 2

It is said that Hercules killed the scorpion in the mountain stream.

Legend 3

There is also a story that the hunter Olivier (Orion) is too arrogant, boasting that no animal in the world is his opponent. A few days later, Hera sent a poisonous scorpion to bite his foot and kill him. So in heaven, we are enemies of each other and live far away from each other. Whenever Scorpio rises from the eastern horizon, Orion leaves in a hurry from the west.

Legend 4 (partly from the Star of Olympus)

Roman mythology tells that Di Anna, the goddess of hunting, once fell in love with Olivier, Poseidon's son. Apollo, the sun god, stopped believing in love because he still felt guilty about Daphne, and prevented Di Anna from falling in love with Olivier. However, Di Anna did not listen to Apollo's advice and insisted on staying with the hunter. Apollo sent a giant scorpion to kill the hunter, and Di Anna drew a bow and shot the giant scorpion to death. In order to commemorate his lost love, Di Anna asked his father Zeus to turn the giant scorpion and hunter into stars in the sky, so he had Scorpio and Orion.

Patron saint: Hades, usually regarded as the ruler of the underworld.
