What is the distribution of 12 constellation in the universe?

signs of the zodiac

The sun runs from west to east on the ecliptic and circles the sky once a year. There are twelve constellations on a belt on both sides of the ecliptic. They are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. People on earth can see them one after another in a year.

Babylonians observed these constellations for a long time, determined the ecliptic through observation, and divided the ecliptic into 12 equal parts, each equal part was 30 degrees, which was called 1 segment. The sun travels around the ecliptic in 12 months/cycle, so it travels on the ecliptic every month 1 segment. In the eyes of the ancients, the sun was Apollo, and its resting place must be a magnificent palace. Therefore, they called the 1 section of the ecliptic 1 palace. In this way, the section 12 on the ecliptic becomes the "zodiac". The names of the zodiac signs are the same as those of the 12 constellation near the ecliptic, namely Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

Although the names of the zodiac signs are the same as those of the 12 constellation near the zodiac signs, they are essentially different. The zodiac indicates the position of the sun on the ecliptic, and the size of each constellation is fixed. It's all 30 degrees, and the time when the sun enters each house is basically fixed. Now the sun comes to the vernal equinox on March 2 1 every year and enters Pisces Palace. Around June 22, I came to the summer solstice and entered the twin uterus; On September 2 1 day, I came to the autumnal equinox and entered the virgin palace. 65438+Come to the winter solstice around February 22nd and enter the Sagittarius Palace.

However, this was not the case before 2000, because under the gravity of the sun and the moon, the rotation axis of the earth did not point to the same position in the sky, but turned around in the sky. This phenomenon is called precession. Due to precession, before 2000, the sun was located in the above four positions of Aries, Cancer, Libra and Capricorn. Different from the ecliptic, the 12 constellation near the ecliptic has different sizes. For example, the width of Pisces is 49 degrees, while the width of Cancer is only 2 1 degree. 12 constellation is not necessarily located on the ecliptic, but distributed within 8 degrees on both sides of the ecliptic.

There are five stars above level 4 in the constellation. The first house of the zodiac, with longitude ranging from 0 degrees to 30 degrees, was originally in Aries, hence its name. But due to precession, it has now moved to Pisces.
