In astrology, Cancer is the fourth sign of the zodiac, ruled by the Moon. Represented by the Crab, Cancer energy is deeply intuitive, protective, and connected to home, family, and emotional foundations. A natal chart for a Cancer Sun reveals the unique ways these core traits manifest in an individual's personality, relationships, and life path.
