How to tell the stars in the sky?

Find a celestial globe or an active star map and compare them.

Pay attention to the direction on the map, that is, north, south, and Zuo Dong is on the right west.

I can't say clearly in a few words.

Constellations in the sky divide the sky into 88 constellations according to arcs parallel to and perpendicular to the celestial equator. In order to study the position and motion of celestial bodies, astronomical imaginary celestial bodies are distributed on a sphere with the observer as the center and the appropriate length as the radius. This sphere is called the celestial sphere. Among them, 29 are north of the celestial equator, 46 are south of the celestial equator, and 13 crosses the celestial equator.
