Constellation origin

Constellation originated in Babylon, one of the four ancient civilizations. The ancient Babylonians divided the sky into many regions and called them "constellations". Around 1000 BC, 30 constellations were proposed. The Tigris River and the Euphrates River flow into the Persian Gulf from northwest to southeast, so it is also called the "two river basin" area.

After the culture of the two river basins spread to ancient Greece, it promoted the cultural development of ancient Greece. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table. In the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. Connect the main bright stars in the constellation with imaginary lines, imagine them as images of animals or characters, and give them appropriate names in combination with fairy tales. This is the origin of the constellation name. Most of the 48 constellations in Greek mythology live in the northern sky and north and south of the equator.

After the Middle Ages, European capitalism rose and needed to expand outward, and the navigation industry was greatly developed. Ships sailing at sea need navigation at any time, and stars are the best street lamps. Among the stars, this constellation has a special shape and is the easiest to observe. Therefore, constellations have aroused widespread concern. 16 when Magellan actually sailed around the world, he not only used constellations to navigate and orient, but also studied constellations.

1922, the General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations, and their names basically followed the historical names. 1928, the international astronomical union officially announced the names of 88 constellations. These 88 constellations are divided into three celestial regions, 29 in the northern hemisphere and 47 in the southern hemisphere, near the ecliptic 12.
