Sun
The Sun is the chart’s central luminary in most Western natal work. Its sign and houses describe conscious identity, vitality, and the life direction one grows toward—not the whole personality alone.
Solar placement by sign is what popular culture calls the “sun sign,” but the full natal-chart requires degree, house, and aspects. The Sun rules Leo in traditional dignity lists; an example solar sign note is sun-in-leo.
Transits to the natal Sun mark seasons of visibility and purpose. In synastry, one person’s Sun contacting the other’s personal planets often highlights recognition and ego rapport. Sign table: zodiac-signs; domicile: dignities; example: sun-in-leo / sign-leo.
