Questions

How long does the Sun take to go through the zodiac?
About 365.3 days for one full circuit as seen from Earth. That is the synodic figure this site computes ephemeris positions against, not a sidereal orbital period, and it is what determines how long the Sun stays in one sign: roughly one twelfth of the cycle, stretched or compressed by retrograde motion and by the eccentricity of the orbit.
Which sign does the Sun rule?
The Sun rules Leo. It is exalted in Aries. It is in fall in Libra. It is in detriment in Aquarius. Rulership is a fixed correspondence, so it holds in every chart; what changes chart to chart is whether the Sun actually occupies one of those signs.
Is the Sun a personal planet?
The Sun is classified here as a luminary. The Sun and Moon are treated separately from the planets in classical sources - they never go retrograde and they define the day and night sect of a chart.
Does the Sun ever go retrograde?
No. The Sun is a luminary, and from Earth its longitude only ever increases, so it has no retrograde period. Any source listing a the Sun retrograde is either using a different reference frame or is in error.
