In astrology, the zodiac is divided into twelve signs of 30 degrees each: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Each sign carries a distinct energy defined by its element (fire, earth, air, water), modality (cardinal, fixed, mutable), and ruling planet. Planets take on the characteristics of the sign they occupy.
