At present, the whole day is divided into () constellations internationally, and about half of them are named after ().

Hello, landlord. At the 1922 conference, the International Astronomical Union stipulated that:

The whole day is divided into 88 constellations, representing 88 different sky regions.

Of the 88 constellations in the sky, 53 are named after mythical images. 65,438+04 was named after instruments and appliances, 65,438+05 was named after exotic animals discovered after the opening of the new air route, and six of them were special (Southern Cross, Indian, Yamaraja, Yufu, Triangle and Southern Triangle) and had no history, so they were named on a whim.

It was the first century A.D., and the ancient Greek astronomer Ptolemy divided 48 constellations, which later generations classified into Ptolemy constellations. These 48 constellations are basically the brightest and most sought-after 48 constellations on the celestial sphere. Later, after the opening of the new seaway 1597, Dutch navigators discovered that there were many constellations in the southern hemisphere that had never been seen in the northern hemisphere, which triggered another upsurge of constellation discovery and naming. This craze did not disappear until 1922, when the International Astronomical Union permanently stipulated the constellations in the sky.

therefore

Internationally, the whole day is divided into (88) constellations, about half of which are named after (mythical images).
