As seen from Earth, the Sun is the brightest star in the universe. It is the center of our solar system, and the vital heart in any horoscope. Without the Sun, there would be no life. The Sun rules your will, your pride, your determination, your heart, health and vitality, the recognition you receive for work well done, your sense of purpose, and motivation for future goals. The Sun is your ego, governing how you see yourself, your self-esteem. This planet also determines how others view you. An essentially masculine force, the Sun also wields influence over the significant men in your life, especially those in positions of authority. This may be your father, your current boyfriend or your husband, a guy-friend, or a male boss or client.
The Sun rules all daylight. In the same way it rules public recognition and self-image by illuminating who we are, the Sun also clarifies the characteristics any planet it touches and reveals truths about that planet. For example, if the Sun and Jupiter communicate in a special configuration, Jupiter’s goodness would be illuminated and made even more brilliant by the Sun. Under the nurturing light of the Sun, Jupiter’s strengths intensify, as do the benefits it bestows upon us.
The Sun takes one year to move through all twelve constellations (signs) of the zodiac. The Sun guards the heart. It is the ruler of the sign of Leo.
