An examination of the waxing and waning influence of demoted planets • Explains in detail how the demotion or proved nonexistence of a planet marks the beginning of a roughly 30-year period in which that planet’s influence wanes • Explores Pluto’s arc of influence on individual and collective life in depth, from its discovery in 1930 to the end of its influence in 2036 • Offers examples from other demoted planets, such as Ceres, whose fifty-year reign as a planet corresponds very closely to the Romantic Era of history Recent research in astrology has shown that the discovery of a new planet correlates with the emergence of a new set of influences in individual and collective life. As John Michael Greer reveals, the opposite is also true: the demotion of a planet correlates with the decline of a set of influences into the background. Although there are several instances of this over the last two centuries, Pluto, downgraded to minor planet status in 2006, is the most striking example.
