Sun in Aries: your identity is built through action
The Sun is identity: what you are building yourself around.
Your identity is built through action. You come alive when you move first, and playing it safe leaves you flat. Boldness is not the risk. The risk is mistaking motion for meaning.
Aries is fire, cardinal and ruled by Mars
The element sets the temperament: fire acts, earth builds, air connects, water feels. The modality sets the motion: cardinal starts, fixed holds, mutable adapts. The ruler is the planet that carries the sign’s agenda.
Your Sun may be in Aries in one zodiac and not the other
The tropical zodiac is tied to the seasons; the sidereal zodiac to the stars. They have drifted about 24 degrees apart, almost a whole sign. So a planet in the first two-thirds of tropical Taurus usually sits in sidereal Aries, and a tropical Aries Sun is often sidereal Pisces.
Neither is wrong. The tropical chart describes how you meet the world; the sidereal chart is the sky as it actually stood. We read both, plus True Sky and the draconic chart, and make sense of all four as one picture.

It depends on the degree. The zodiacs are about 24° apart, so a late-Aries tropical Sun is usually sidereal Aries too, while an early one is sidereal Pisces. Your chart settles it.
