Sun
Identity
The sense of self expressed in a reading. This is symbolic reading language; your actual placement comes from your birth details.
Find your Sun, Moon and risingThe Sun describes identity and deliberate direction
A natal Sun reading concerns what a person identifies with and wants to express through their choices. Purpose is part of this symbolism: the activities or commitments that feel worth taking responsibility for.
The Sun differs from the Moon, which concerns emotional needs and familiar responses. Someone can want public responsibility while also needing a quiet private life. Reading both placements gives room for that difference.
The sign describes a style of expression. The house places the subject in an area of life. Aspects connect it with other planetary themes. A Sun sign alone leaves those relationships out.
A worked comparison
The house changes the reading
Compare an Aries Sun in the 4th with an Aries Sun in the 10th. Initiative is a shared sign theme. The first reading places it in home and private life; the second places it in public responsibilities.
This is an illustrative reading, not a description calculated for you.

Sun's sign and degree
The sign identifies a 30-degree section of the tropical zodiac; the degree locates Sun inside it. A position near the end of a sign still belongs to that sign until it crosses the boundary.
Near a sign boundary, use the year and birth time rather than a fixed birthday list.
Explore the zodiac signsHouse placement and birth time
Astriel defaults to Placidus. Find Sun between its calculated starting cusp and the next cusp. The birth time and location determine those boundaries. A sign name alone cannot identify the house.
With an approximate or unknown time, houses remain unavailable. Planetary signs and ranges can still be shown; missing house data is not a missing area of life.

Look for contacts involving Sun in the aspect table. The other factor, angle and allowed orb all matter. An aspect label describes a calculated relationship, not an event that must happen.

Traditional and modern rulership
Sun traditionally rules Leo. If one of these is your rising sign, Sun is your chart ruler under Astriel's method.
A ruler relationship does not tell you the planet's actual sign, house or strength.
