I would imagine that humanities on other planets have their own astrology.
How does this work? Do they have their own equivalents of Mars, Saturn, etc...or do they have other planets that possess completely different energies, unlike any in our solar system?
It seems to me that our astrological planetary energies are very archetypal, and thus universal, but obviously the astrology of other worlds would not utilize the planets of our solar system.
What about the constellations of the signs?
