Origin of constellations:
In ancient times, in order to facilitate the identification of directions and observation of celestial phenomena during navigation, the stars scattered in the sky were combined with imagination. Together, half of them were named in ancient times, and their naming methods are based on the myths and shapes of ancient civilizations. The other half was named in recent times, often after navigational instruments. In ancient times, due to different regions, the ways of "Lianliankan" were also different! In the 21st century, the world has unified the constellation map, which divides the sky into 88 regions and 88 constellations.
The constellation we generally talk about refers to the sun constellation, which means that people on the earth are centered and the sun is seen moving in orbit at the same time (Greek ZODIAC: means ~ the circle formed by animals , also known as the "ecliptic"), the constellation of that person is determined by the position of the constellation. In fact, this kind of constellation originated from the West, and the East also has its own constellations, and the arrangement of the lunisolar calendar is different. ?
More than 2,000 years ago, the Greek astronomer Hipparchus (190-120 BC) divided the zodiac into twelve sectors in order to mark the position of the sun on the ecliptic. , taking the vernal equinox as 0°, counting from the vernal equinox (i.e. zero degree of the ecliptic), a house is formed every 30°, and is named after the main constellations contained in each house at that time, in order Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and other signs are called the twelve signs of the zodiac. There are twelve constellations in total.
