planets and ascendant

[Big Dipper]

hey. what does it mean for someone when a planet crosses their ascendant, for example the sun? also for descendant, midheaven and ic. *finger pistols*

 

[fuoco blu 666]

It means that that planet will have a lot of importance in a prediction, Mars must be considered if retrograde, Jupiter, Saturn, Uranus, Neptune, Pluto with the prediction methods of the solar and lunar revolution, fast planets do not have much meaning because their transits last too long little in terms of time, it should last at least until the next lunar revolution.
The planet will take on different meanings for each corner, the ascendant therefore a transit in the first house or on the planet of the ascendant, the ruler of the natal chart is the most important of all.
