What is a constellation?

Constellation refers to the stars in the sky. In fact, the stars in the same constellation have no actual relationship with each other, but their projection positions on the celestial sphere are similar. Since ancient times, people have been interested in the arrangement and shape of stars, and naturally linked some stars with similar positions to form constellations.

Constellations are divided into Polaris, South Star and Zodiac. The whole day is currently divided into 88 constellations. Constellations are generally named after musical instruments or Greek mythical figures.

Constellation originated in Babylon, one of the four ancient civilizations. About 5000 years ago, a group of Babylonian shepherds lived a nomadic life in Mesopotamia. In their wandering life as shepherds, they still don't forget to observe the twinkling stars in the night sky every day. Over time, they can see the regular changes of time and season from the dynamics of the stars. Every night, they look at the sheep, observe all kinds of stars, connect the brighter stars with each other, associate all kinds of animals, utensils and even gods they believe in from the connected shapes, and name them, creating the so-called constellation.
