What is the biggest constellation in the sky?

The biggest constellation in the sky is "Long Snake". It is like a python, stretching from east to west 102 (the sky is 360), with a width of 42 from 7 north to 35 south of the celestial equator and an area of 1300 square degrees, accounting for 3.2% of the total sky area! In the night sky in May, when snakehead rises from the south, its tail is still hidden under the horizon in the east!

However, constellations are divided by people's imagination.
