Because of a 26,000-year-old process known as “precession,” the stars appear to migrate over time. The wobble in the Earth’s rotation is to blame for this.

What makes my zodiac sign unique?
The Sun sits between the Earth and each zodiacal constellation for varied amounts of time due to the size of each constellation, the ecliptic passing through greater or smaller areas of each constellation, and the speed of the Earth around the Sun altering during its orbit.
Is it possible for a person’s zodiac sign to change?
No, it’s more like once every 30 years or so. (Thank G, you’ve got some time to think about it.) “Each sign has 30 degrees, and the advanced sun moves less than a degree per year, so this shift is really slow,” Montfar explains.
Why are the signs of the zodiac incorrect?
The main reason astrological signs don’t align with the zodiac is due to precession, a wobble in the Earth’s spinning axis. The Earth bulges somewhat at the equator as a result of its rotation, similar to how a skater’s skirt fanned out as she spins. The Moon’s and Sun’s gravitational pulls on the bulge, causing the Earth to wobble like a top. Over the period of 25,800 years, the wobble causes the Earth’s axis, which is the center line around which it revolves, to swing in a leisurely circle.
The view of the zodiac from Earth is altered as a result of this movement, with the constellations appearing to slide to the east by around a degree per human lifetime. Hipparchus of Nicaea discovered precession with his naked sight approximately 150 B.C., though it was gradual.
The vernal equinox, or the first day of spring, was in Aries in ancient times. It went into Pisces circa 100 B.C. due to precession, where it is today and will remain until 2700 A.D., when it will move into Aquarius, and so on. It will finally return to Aries after 25,800 years, and the cycle will begin again.
Astrology and its predictions about fate and personality can be entertaining as a game. The subject, on the other hand, has no scientific foundation. It’s the equivalent of the board game “Monopoly” in the real estate market.
Astrology draws attention away from the planets’ very real affects, namely their gravitational interactions with one another, which create true changes in the shapes, sizes, and tilts of their orbits. Past ice eras on Earth were most likely triggered by such shifts. Direct impacts between Earth and celestial bodies can result in dramatic changes, such as the 66 million-year-old impact of an asteroid off the Yucatan Peninsula, which resulted in the extinction of dinosaurs and the advent of mammals.
Astronomical studies will someday allow such events to be predicted, however astrological forecasts will lead to nowhere.
Who designed the zodiac signs?
The 12 zodiac signs, one of the earliest notions of astrology, were devised by the Babylonians around 1894 BC. The Babylonians lived at Babylon, which is roughly where modern-day Iraq is located. Babylon was one of the most prominent ancient Mesopotamian towns.
