Is Ophiuchus the longest constellation in the whole day?

The largest constellation in the celestial sphere, with the longest east-west direction. This is a constellation that appears in the spring night. Located in the south of the ecliptic, it winds in the south of Cancer, Sextant, Grand Duke, Raven and Virgo, between Canine and Libra. To the south of Cancer, at the lower right of Leo Xuanyuan 14, there are five three dragons.

Four stars form a small circle, which is the head of a snake. There is a lonely red second-class star in the southwest of Xuanyuan 14th. Because there are no other bright stars nearby, it is often called "orphan", which is the heart of a long snake. Other dark stars in the constellation meander into a long line.

Legend has it that Xu Dela is a fierce and terrible water snake with nine snake heads. This monster can spit poison gas from nine mouths and feed on wild animals and people. In order to destroy it, the great hero Hercules and his friend Olaus came to the place where Xu Dela lived. Hercules swung a big stick and smashed nine heads one by one, but immediately after smashing 1 basilisk heads, 1 new heads grew. Later, Hercules found a way for Olaus to burn the new snake head with burning branches. Finally, he killed the snakehead, buried the snakehead's body in the ground, and pressed a boulder on it. Xu Dela, the water snake, was eliminated. Zeus, the god of gods, praised Hercules for this achievement, and lifted the water snake he conquered to the sky and became Ophiuchus.
