Ophiuchus, the longest and largest constellation among the 88 constellations?

Constellation 88 takes you to know Ophiuchus, the longest and largest of the 88 constellations. In the spring night sky, Ophiuchus winds in the south of the constellations such as Cancer, Lion, Maiden and Libra, spanning a quarter of the whole day. The stars rose in the east half an hour later than Xuanyuan Fourteen and set in the west two and a half hours earlier than Xuanyuan Fourteen.

Ophiuchus is the longest and largest of the 88 constellations in the whole day, with a span of 1/4 days, and it is also one of the 48 constellations listed by Ptolemy. Contains the ancient constellations of China: Liu Su, Waichu, Su Xing, Zhang Su, Pingping, Forever Summer Watch, Clear Autumn and Zhanche. Except for a red second-class bright star (that is, the alpha star of Ophiuchus, which China called "Star One"), all the other stars are very dark, so Ophiuchus is not very noticeable. To the south of Cancer and to the lower right of alpha star Leo (Xuanyuan XIV), there are five third-class stars and fourth-class stars forming a small circle, which is the head raised by the long snake. Located in the southwest of Xuanyuan 14, constellation I is equivalent to the heart of a long snake. Not to be confused with Aquarius. Latitude changes are located at +54 and? 83, the best observation month is April.

In the spring night sky, it winds in the south of the constellations such as Cancer, Lion, Virgo and Libra, spanning a quarter of the whole day. The stars rose in the east half an hour later than Xuanyuan Fourteen and set in the west two and a half hours earlier than Xuanyuan Fourteen. The outline of a star and many dark stars symbolizes the body of a long snake. It swims southeast under Leo and Virgo, and its tail reaches Libra. On the "back" of Ophiuchus, the Grand Duke skillfully connected it, as if he had specially put a big bowl on Ophiuchus. There is a crow (crow's nest) on the tail of a long snake extending eastward, and it keeps pecking at it with its mouth. Perhaps its relatives were killed by a long snake venom and are now taking revenge.

Although Ophiuchus is very long, there are no bright stars. Except for a red second-class bright star (that is, the alpha star of Ophiuchus, which China called "Star One"), all the other stars are very dark, so Ophiuchus is not very noticeable. To the south of Cancer, there are five third-class stars and fourth-class stars in the lower right of Leo alpha star Xuanyuan 14, which form a small circle, which is the head raised by the long snake. Located in the southwest of Xuanyuan 14, constellation I is equivalent to the heart of a long snake. There are no other bright stars around the star, so Arabs call it a "lone ranger".

Because Ophiuchus is very long, there are many adjacent constellations, such as Pumpkin, Cancer, Canidae, Centauri, Raven, Grand Duke, Leo, Libra, Wolf, Unicorn, Tail, Compass, Sextant and Virgo.
