When will that kind of prophet be included in the zodiac?

At present, there are indeed 13 zodiac signs, that is, Ophiuchus is added to the well-known 12 zodiac sign, which is determined according to the constellation range set by the International Astronomical Congress 1928. The following article is taken from AEEA Astronomy Education Information Network, which is a good choice to explore the universe online! Astronomical exhibitions and educational activities. June 8, 2003 Summer Constellation (8): Ophiuchus Provider: Chen (Group)

NMNS) Description: Ophiuchus, one of the zodiac signs, is located in the south of Hercules, north of Scorpio and Sagittarius, and west of the Milky Way. Ophiuchus is the only constellation in the starry sky interwoven with another constellation (Ophiuchus), and it is also the only constellation in the starry sky that crosses the celestial equator, ecliptic and "Silver Road" (the Milky Way seems to have a belt-shaped circular orbit in the background of the celestial constellation, which is called "Silver Road" if traced back along the galactic center line). It is a big and wide rectangular constellation. The Milky Way has a prominent reach in Ophiuchus, which shows the widest range of the Milky Way. The lower left corner of the above picture is the naming schematic diagram of this constellation, Ophiuchus, SHIELD and so on. The snake man grabbed the giant snake with both hands. & nbsp; Although the zodiac passes through Ophiuchus, Ophiuchus is not one of the zodiac 12 palaces. Every year around165438+1October 29th, the sun enters Ophiuchus from Scorpio, and it does not leave Ophiuchus until 65438+February19th. None of the 24 solar terms on the ecliptic is in Scorpio, but Ophiuchus has a "heavy snow" solar term. This is because the zodiac sky of Ophiuchus once belonged to Scorpio in ancient times, but the bright star at the tail of Scorpio is too south, and Ophiuchus' feet have nowhere to be placed, so this part of the sky has nothing to do with the extra starry sky that constitutes Scorpio's body, and it belongs to Ophiuchus from Scorpio. & nbsp; Ophiuchus has a famous "Barnard Star", which is only next to proxima centauri, one of the "α Cen". Barnard Star is the second closest star to the sun, about 5.97 light years. The brightness is about 9.56 apparent magnitude, and it is also the fastest star in the whole day. Every 180 years, it will move a full moon's apparent diameter distance on the celestial sphere. Legend: Kay Long Xing of Sagittarius took a fancy to Apollo's beloved son Ascledius and taught him all his knowledge. With his father, the god of medicine, and an excellent teacher, Ascledios immediately surpassed the teacher and became a very excellent doctor. He treated patients who other doctors had given up treatment, saved seriously injured patients, and soon even had the ability to bring patients back to life. Hades said angrily, "What a terrible thing! If this continues, there will be no one in the country of the dead. " He quickly told Zeus, the king of the gods, * * *: "The fate of the world has long been doomed. Can I change it at will? Even god forbid to do such a thing. What's more, he raised the dead into people, which is really clever. Zeus also thought that the order of the universe would indeed be chaotic, so he killed Ascledius with lightning. But as a doctor, his great achievements can not be ignored, so Zeus added him to the constellation, and Ophiuchus was born. After Asclepius's death, he was even more respected. Because he built a temple in Urus, patients who came to ask for help always lined up. Those patients go to the temple to support him and pray for him, and then when they fall asleep, Ascledius will appear in their dreams and tell them how to cure their diseases. Ascledios, who became Ophiuchus, held a snake in his hand, because Ascledios used snake venom as medicine before his death. In the eastern Mediterranean, snakes have always been a sacred animal and are cherished and respected; In a hospital called Asclepion, snakes are not only used as spells or witchcraft, but even snake scare therapy is used. They think that snakes have strong vitality, so they are related to treating diseases. Moreover, after the snake dies in the cold winter, the "corpse" will not rot until spring. If you agree with thirteen constellations, the changes of each constellation and date of birth are as follows: Muyang: 04/ 19-05/ 13 Taurus: 05/ 14-06/22 Gemini: 06/23-07/2 1 cancer. 1 1-09/ 16 Virgin: 09/17-10/31Libra:110/. 24- 1 1/29 Sagittarius:11/30-12//7 Sagittarius:12/18 17 Aquarius: 02/ 18-03/ 12 Pisces: 03/ 13-04/ 18 Photo reference: LCSD/CE/ Museum/Space/FAQ/Star.

There is a Ophiuchus frame every year!

Ophiuchus symbolizes that Asclepius, the Greek god of medicine, holds a big snake (Ophiuchus), which is a symbol of traditional medicine. Ophiuchus is a big constellation across the equator of the celestial sphere. It is the latest zodiac sign (explained on the previous page). The position of the ecliptic is the yellow dotted line in the picture, and Ophiuchus' right foot passes through the ecliptic. Important observation: Barnard: the second closest star to the sun, 5.9 light years away (the nearest distance is about 4 light years). M 10: It is a globular cluster, which can be seen with binoculars, especially with medium-sized telescopes. Distance to Earth 14000 light years. Focus of observation: name, category and grade, other features of observation instruments: Ophiuchus A (the brightest star) 2. 1 Ophiuchus R binoculars -4.6 and other stars; Stars with higher magnification such as 6.8 and 7.3; Next to the brightest star, there is a companion star Ophiuchus 36 (Tianjiang II). Ophiuchus 70. 4) The binoculars with slightly larger aperture 4.2 and 6. 1 are composed of yellow and orange dwarfs, which are 0/7 light years away from the Earth and have an orbital period of 88 years. Seen from the earth, these two stars are slowly moving away. Barnard's Red Dwarf 9.5 and other telescopes are 5.9 light-years away from the sun's second closest star. The temperature is low, dim and invisible to the naked eye. M 10, M 12 two spherical cluster binoculars M 10 from the earth 14.

000 light years. M 12 Earth distance 18

000 light years. The distance between M 12 and M 10 is 3 degrees, which is about half the size of a full moon. Only medium-caliber telescopes can identify the stars between them. The binoculars of NGC 6633 open cluster are about the size of a full moon. The IC 4665 open cluster telescope is large and sparse.
