What constellation is September 26th _1997 What constellation is September 26th?

The constellation of the Gregorian calendar on September 26th: Libra? (Date of birth: September 23rd-65438+1October 23rd).

Constellation is an indispensable part of astrology and a combination of stars in the sky. Since ancient times, humans have associated a small number of stars with their mythical figures or artifacts, which are called "constellations".

Constellation is a means to determine the position of the sky in almost all civilizations and is widely used in navigation. The division of constellations is completely artificial. Different civilizations have different divisions and names.

Constellations didn't have a unified and clear precise boundary until 1930, when the International Astronomical Union divided the sky into 88 official constellations with precise boundaries, so as to unify the complicated constellation division and make every star in the sky belong to a specific constellation. Most of these official constellations are based on ancient Greek myths handed down from the Middle Ages.

In contrast, some star combinations are widely circulated, but they are not considered as official constellations, such as the Big Dipper.

The origin of the twelve constellations:

The well-documented constellations originated in Babylon, and the Babylonians put forward 30 constellations around 1000 BC.

After Mesopotamia (Babylon) was introduced to Greece, ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table. Claudius Ptolemy, an ancient Greek astronomer, compiled 48 constellations according to his astronomical achievements at that time.

After the Middle Ages, the rise of European capitalism needed to expand outward, and the navigation industry was greatly developed. Ships sailing at sea need to navigate at any time. Stars are the best lights. Among the stars, the constellation has a special shape and is the easiest to observe. Therefore, constellations have received extensive attention. When Magellan sailed around the world, he not only used constellation navigation and orientation, but also studied constellations.

1922, the general assembly of the international astronomical union decided to divide the sky into 88 constellations, and the names of these constellations basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12.

The constellation we usually say is the zodiac. Each of them has some myths and legends about himself.
