Capricorn and Cancer are opposite signs in astrology; compatibility between opposites is often good as they provide a special balance of qualities, each offering something the other lacks. In this case, Cancer is a deeply emotional and intuitive sign, whereas Capricorn is cool, practical and logical. When these two get together as lovers or parents, the family will have the best of both worlds, able to call upon the powers of both the head and the heart. Capricorn and Cancer compatibility thrives because both signs are cautious and quite serious too, so they work hard at the relationship and are willing to understand one another’s differences.
