There are traditionally 12 zodiac signs in Western astrology. These are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces

. However, in astronomy, there are 13 constellations on the ecliptic, the path the Sun appears to follow through the sky. The 13th constellation is Ophiuchus, located between Scorpio and Sagittarius. Although Ophiuchus is recognized astronomically, it is not traditionally included in the zodiac signs used in astrology, which is why the zodiac system has remained with 12 signs

. In summary:

• 12 zodiac signs in traditional astrology.
• 13 ecliptic constellations astronomically, including Ophiuchus.
• The 12-sign system is the standard in horoscopic astrology.

Thus, the number of zodiac signs is 12, with the occasional mention of a 13th (Ophiuchus) in some astronomical contexts but not commonly used in astrology
