Pluto In Scorpio. Nineteen Eighty-Four, the novel by George Orwell, made a lot of people apprehensive as that year loomed. Astrologers discussed Pluto’s entry into its own sign at the time (1983–4), and the phenomenon became the theme for astrological conferences. It was evident that Pluto was signalling the development of HIV and AIDS. This illness is extremely Scorpionic in character, and it was not difficult to predict the devastation it would cause as the planet progressed through its own sign (until 1995). While its influence from Scorpio will increase the Scorpio characteristics of those with a Scorpio Sun, Moon, or Ascendant sign, there is no added danger of these individuals contracting the illness.
