Pluto Cycles

Pluto Cycles - Astrology Encyclopedia

Definition of Pluto Cycles The application of Bode's Law roughly coincides with the distances of the planets from the Sun; except in the case of Neptune, where it breaks down entirely. However, D. E. Richardson, of the Armour Research Institute, as noted in Popular Astronomy for January 1945, has discovered a formula which accurately yields the planetary distances. The only discrepancy of over 0.1 per cent between distance values computed from this formula, and the observed values, occurs in the case of Pluto. Furthermore, his formula confirms what Wilson found from a study of medieval records as to the knowledge of the ancients, viz., that there are 13 orbits in the Solar System: one within the orbit of Mercury (Vulcan), and two beyond the orbit of, Pluto. According to this formula the planet next beyond Pluto should have a mean distance of 74.2 astronomical units, and a sidereal period of 640y; the outermost planet, 137.4 A.U., and 1608y. The mean values in tropical years would then be 625y and 1515y.

Recent discoveries by certain outstanding non-astrological investigators are interesting, even if as yet speculative, in the fact that they check with the periods of the two planets which there is some reason to believe lie beyond the orbit of Pluto. Studies of the Culture Cycle, by Jean Bradford, and by Petry, the great Egyptologist, indicate a period of about 1500 years as the duration of a Culture: subdivided into 6 culture -- phases of about 250 years each, in each of which certain psychologically different basic components receive special emphasis. She has correlated recognizable physiological differences with endocrine imbalance, based on the work of Dr. Berman, recognized endocrinologist, revealing wherein both the psychological and the physiological characteristics of a culture-phase display a different sense of Space, dimensional in nature.

The work of Dr. Ellsworth Huntingdon of Yale, outstanding geographer, climatologist and cyclologist, indicates a cycle of about 640 years in the migrations of peoples.

Clearly these suggest a Pluto cycle, of a sidereal period of 247.7 years, or 245 1/3 tropical years, the interpretations of which agree with certain conclusions reached by Dane Rudhyar, astrological student of cultures and civilizations, concerning the Pluto period and its correlation with the style of a period. The sidereal period of the planet next beyond Pluto correlates to the Migration cycle of Dr. Huntingdon. The 1500-Year Culture period of Bradford and Petry correlates to the tropical period of the hypothetical outermost planet. Since in all Culture-cycles, Mrs. Bradford finds that changes of phase occur in years divisible by 250, it is notable that close to these dates Pluto is at its perihelion (13�+) - its nearest point to the Sun. Its next perihelion passage will be in 198g, 11 years before her date. The first perihelion passage of this epoch was 8 A.D., 8 years after her date. This is highly significant, since Pluto is nearer to the Sun than Neptune during nearly 5 years before and after its perihelion pas- sages. Thus, as Rudhyar has suggested, Pluto "fertilizes" Neptune once in each cycle by crossing within its orbit. It is also of interest to note that Neptune's aphelion nearly coincides with Pluto's perihelion. Thus of all planetary orbits theirs are the most singularly related.
