What is a constellation? How did the thirteen constellations come from?

What is a constellation? In ancient times, in order to meet the needs of navigation and positioning, some stars were connected and named this connection. The name of this connection is constellation. The origin of the twelve constellations is that the ancients saw the sun's trajectory in the sky (rising in the east and setting in the west) passing through twelve constellations, so they gave these constellations mysterious significance.
