The Sun represents core identity, ego, vitality, and purpose in astrology, reflecting one's central sense of self and life direction.
Definition
In astrology, the Sun signifies the core of a person's identity, representing the essence of who they are and their conscious purpose in life. As the center of the solar system, the Sun symbolizes vitality, creativity, authority, and the drive to shine. It governs the zodiac sign Leo and is exalted in Aries, linking it to themes of leadership, self-expression, and individuality. In a chart, the Sun reveals where a person seeks recognition and fulfillment, often pointing to areas of life where they aspire to feel significant. The Sun is considered a 'luminary' rather than a traditional planet and plays a pivotal role in determining personality traits and life goals. It is crucial to interpret the Sun's placement by house, sign, and aspects to other planets to fully understand how an individual expresses their core essence. The Sun’s position by transit or progression can also highlight periods of growth or shifts in life focus. Edge cases include combust planets (those too close to the Sun), which may struggle to express their full potential due to being overshadowed by the Sun's dominance.
In a chart
In a natal chart, the Sun is identified by its zodiac sign and house placement. Consider its aspects to other planets, which modify its expression. For example, a Sun in the 10th house often points to a focus on career and public achievements, while a Sun in the 4th house emphasizes home and personal roots. Ignore minor aspects unless they reinforce major themes.
