Well...The astrology will never be affected even if there were some contributions by Pluto itself. Pluto is still there, where it was for centuries. All these guys have done is taken the pluto out of the Planet list. It will not change any effect of pluto on other planets, it will not change its path of rotation, magnetic effect, gravitational forces etc. So how will it affect the astrology. The only thing that will change is Text book. People will not read Pluto as a planet. Tyatti ta ho ni, haina ra??
