I'm not much into astrology, so I don't know the ramifications, if there are any, on an astrological scale. Whether they call it a planet or dwarf planet or whatever else they want to call it, I wouldn't think it would or should have any affect. It's still the same mass in the solar system, it still has the same orbit, it's still in the same place it has been for millions of years.
A rose by any other name...
I fully concur.
For astrologers to use it, they have to empirically observe it first. They also have to have a theory of how it might work in the psyche.
Most astrologers, I think, don't think that the physical characteristics of the planets mean anything. Most I know take a mystical approach, or a Jungian, "archetypal" or "synchronistic" approach; the planets just somehow mirror the soul, and can characterize and predict things in the life of an entity (a state, organization, enterprise or individual) by virtue of that synchronistic quality.
For me, the solar system is a web of magnetic and gravitational influence, and everything in it is influenced to a greater or lesser degree by everything else in it. The Sun is of course by far the most important thing; for Earth, the Moon is next (and the Earth itself of course!). But celestial bodies also affect us with their energy. Except for the Sun and Moon, the planets are subtle but persistent forces in nature and our lives. It doesn't matter that Jupiter's energy doesn't knock you over, or overtly "cause" anything - it is persistent and constant and measurable force; astronomy quantifies the force, but what astrology tries to do is *qualify* the effects of that force.
I don't think Pluto - or any of the asteroids like Ceres - can be shown to have much effect electromagnetically or gravitationally on earth, or the Sun (as the other planets do). All together, they make up quite a weight, but except for a few chance encounters, Earth is pretty much unaffected by them.
The other planets are like anchors of the solar system - if any one of them were destroyed, we would notice it to a greater or lesser extent.
