How many constellation areas is the whole sky divided into?

The whole sky is divided into 88 constellation areas.

In ancient times, in order to facilitate navigation and observe astronomical phenomena, people connected the scattered stars in the sky through imagination. Half of them were named in ancient times, and their naming methods include myths and epics of Mesopotamia, Babylon, Egypt and Greece.

The other half is mostly in the night sky in the southern hemisphere. It was named only in modern times and is often named after navigation instruments. 1928, in order to unify the complicated constellation division, the International Astronomical Union divided the sky into 88 constellations with precise boundaries, so that every star in the sky belongs to a specific constellation.

The development of history

In ancient times, the way to look at the starry sky varied from region to region. Now the world divides the sky into 88 regions and 88 constellations according to the constellation map. The constellation we usually say refers to the sun constellation; That is, people on the earth are the center, and at the same time we can see which constellation the sun is in orbit, so we can say what constellation that person is.

More than 2,000 years ago, Greek astronomer Baccus divided the ecliptic into 12 segments, with spring as 0 and every 30 since the vernal equinox, and named them after the main constellations contained in the palaces at that time, namely, Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius and Capricorn.
