every planet definetly contributes to physical appearnce some more than others. mars more than mercury perhaps, but maybe if its conjunct sun the person becomes more mercurial.
the fixed star modulation is really fascinating as well as trans-neptunians and asteroids.
nietzche has Orcus conjunct his ascendant.
"A similar approach can also be applied to the motion of planets. If Earth were the only planet to circle the Sun, its orbit would follow a precise elliptical path, but the gravity of the other planets disturbs the motion. Scientists found that it impossible to calculate the precise motion of the planets over very long periods of time or even prove that Earth will not one day be flung out of the solar system."
let me try to figure out the axis of influence.
DC can be a demeanor of appearing to others in terms of otherness.
for example if someone is walking down the street with saturn DC they look serious to the world.
AC is how one feels expressive and what other people get out of it.
for example if they have cancer asc with saturn DC they look soft, but also look like they are up to something of integrity.
the MC is more accentuated when the person is in their little area of doing what they are good at.
it can also affect job interviews, and the lingering feelings of authority that someone has.
the IC is probably more how the parents and childhood friends appear to them. it can also be the look that is carried with them from child-hood to adulthood.
