Astrology has long fascinated people seeking insight into their relationships, and zodiac sign compatibility is one of its most popular applications. By examining the interplay of the 12 zodiac signs—Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces—astrologers assess how well individuals might connect in love, friendship, or professional partnerships. Compatibility is influenced by the signs’ elements (Fire, Earth, Air, Water), modalities (Cardinal, Fixed, Mutable), and planetary rulerships, which shape their core traits and interactions.
