Sun stands for identity, vitality, and the self you are building. It rules leo, and the 5th-house themes of creation and visibility. Astronomically it is the star at the center; everything else in the chart is seen from its light.

The astronomy, briefly
Astrology ignores almost nothing about the sky, but it does sort bodies by how fast they move. Sun takes 1 year (about 30 days per sign). That pace matters: fast bodies describe personal, day-to-day patterns, while slow ones describe whole generations. When someone says “everyone my age has Pluto in the same sign,” this is why.
Reading Sun: the three questions
Every placement answers three questions. What is it (the planet: here, Sun)? How does it behave (the sign)? Where does it act (the house)? Take Sun in Gemini, the receipt above. You would read the function (identity, vitality, and the self you are building) in Gemini's style, and then look up which house it occupied that day for that observer. Same planet, different story per person. The house is why two people with the same placement can live it differently.

FAQ
What does Sun mean in a birth chart?
Sun stands for identity, vitality, and the self you are building. In your chart, its sign shows the style it comes in and its house shows the area of life where it works. Read our birth chart guide for the full method.
How long does Sun stay in a sign?
1 year (about 30 days per sign). That pace is why some placements feel personal (fast bodies like the Moon) and some feel generational (slow ones like Pluto, which a whole cohort shares).
Can Sun be retrograde in my chart?
Yes, every planet except the Sun and Moon can appear retrograde. A retrograde planet is read with more inward focus. Your chart's positions table flags Rx bodies straight from the ephemeris.
