Final answer:
Zodiac signs are based on the position of the Sun at one's birth. Due to precession, the stars in the constellations have shifted, making today's astrological signs not align with the actual constellations as they did in ancient times. Astrology's predictive power has been scientifically tested, showing no significant results in correlating zodiac signs with success.
Step-by-step explanation:
The zodiac signs are determined by the position of the Sun at the moment of your birth, and they are divided into 12 sectors, each associated with a constellation. Originally, each zodiac sign corresponded to the position of the Sun in the respective constellation, but due to the precession of the equinoxes, the real stars have shifted their positions. Therefore, the astrological signs that we refer to today no longer align with the actual constellations in the sky during one's birth.
The process of creating a horoscope requires charting the positions of the planets, including the Sun and Moon, at the moment of an individual's birth. While astrology remains popular, scientific tests have shown that sun sign astrology does not predict personal traits or likelihood of success in a statistically significant manner, suggesting that the distribution of birth dates among professionals in various fields is random, without any preference for certain zodiac signs.
