The Guardian Planet of Cancer is the Moon, which is the only natural satellite of Earth. In astrology, the Moon represents emotions, intuition, and subconscious desires.

As the ruling planet of Cancer, the Moon influences the deep and complex emotional nature of those born under this sign. They are sensitive, compassionate, and nurturing individuals who value relationships and connections with others. They also possess a strong intuition and are often guided by their gut feelings.

The Moon's influence on Cancer is also reflected in their tendency to have mood swings and emotional ups and downs. They can be highly reactive to their surroundings and may retreat into their shell when feeling overwhelmed or threatened.

Additionally, the Moon plays a significant role in the different phases of the lunar cycle. This corresponds to the cyclic nature of Cancer's emotional state, which ebbs and flows like the tides. During the full moon, Cancer's emotions may be intensified, whereas during the new moon, they may retreat into introspection and solitude.

Overall, the Moon's guidance on Cancer is profound and multifaceted, shaping their emotional landscape and intuitive abilities. It is a vital force that nurtures and sustains their innermost needs and desires, giving them a sense of security and belonging in the world.
