Have you ever gazed up at the night sky and wondered about the stories hidden among the stars? In the western tradition, the world of astrology has given birth to the 12 zodiac constellations. These constellations, named after the signs of the horoscope, have captured our imagination for centuries. Let's embark on a journey to explore the fascinating world of star constellations and the mysteries they hold.
The Zodiac Constellations: Guardians of the Night Sky
In total, there are 88 officially recognized star constellations in the sky. However, the zodiac constellations, which include Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces, hold a special place in our hearts. These constellations trace their origins back to ancient astrological practices.
The zodiac constellations travel along a narrow region of space called the ecliptic, spanning roughly 20° wide. This apparent path is followed by the Sun, Moon, and planets throughout the year. Unfortunately, the Sun's brightness obscures our view of these constellations during the daytime. But if we could see the stars during the day, we would witness the Sun slowly drifting from one zodiac constellation to the next over the course of a year.
Astrology vs. Astronomy: Unveiling the Differences
In the realm of astrology, the zodiac constellations, also known as astrology signs, are divided into 12 equal segments of the sky, each 30° of longitude wide. As the Sun makes its annual 360° journey across the sky, it spends approximately one month in each zodiac sign.
However, in the world of astronomy, the boundaries of the zodiac constellations are not evenly sized. This disparity affects the number of days that the Sun spends in each constellation. Even an unofficial thirteenth zodiac constellation called Ophiuchus has made its way into modern boundaries, intersecting the ecliptic. The varying sizes and durations are highlighted in the list below:
- Sagittarius (32 days)
- Capricornus (23 days)
- Aquarius (24 days)
- Pisces (38 days)
- Aries (25 days)
- Taurus (37 days)
- Gemini (31 days)
- Cancer (20 days)
- Leo (37 days)
- Virgo (45 days)
- Libra (23 days)
- Scorpius (7 days)
- Ophiuchus (18 days)
