There are countless constellations in the Milky Way. Why is the most famous one only 12?

Nowadays, young people are particularly interested in constellations, so do you know the origin of 12 constellation? In fact, constellation is synonymous with divination orientation, and each birth orientation corresponds to a constellation. When everyone is born, the corresponding constellation is likely to affect your personality, luck, talent and so on.

We usually call it the "zodiac sign". To put it simply, the ecliptic is the great circle that the earth's orbital plane expands infinitely and intersects with the celestial sphere, that is, the ecliptic. When we study geography, we all know that the earth revolves once a year, but we usually can't see the slow movement of the stars and the moon unless we zoom in. In fact, the stars and the moon move in the same direction as the earth. They move once a year, which is geographically called the annual movement of the earth.

The ecliptic passes through 12 constellations every year, which is also a recording method for ancient astronomers to record the positions of various constellations and distinguish the direction of divination. Moreover, the trajectory of the sun and the earth will pass through 12 constellations from the vernal equinox, namely Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn and Aquarius.

The ruler of Gemini is Mercury, which is also the third sign of the zodiac. Cancer is the fourth house of the zodiac, the ruler is the moon, Leo is the fifth house of the zodiac, Libra is the seventh house of the zodiac, Venus is the ruler, and Scorpio is the eighth house of the zodiac. Rulers are Pluto and Mars, Sagittarius is the ninth sign of the zodiac, Jupiter is the ruler, Capricorn is the tenth sign of the zodiac, Saturn is the ruler, and Aquarius is the eleventh sign, which is called "Genius Constellation" or "Future Constellation".
