A horoscope sign, also known as a zodiac sign, is one of the twelve divisions of the zodiac, each of which is named after a constellation. In Western astrology, the twelve horoscope signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. These signs are based on the positions of the sun, moon, and planets at the time of a person's birth. Each horoscope sign is said to have its own unique characteristics and personality traits, which can influence a person's life.
