Astronomical Data for

the Transneptunian factors

of Alfred Witte and Friedrich Sieggrün


data compiled by L Blake Finley, M.A, ABD-2

(revised and updated April 2011)


Beginning in the 1920s, the surveyor, amateur astronomer, and astrologer Alfred Witte, in a search for astronomical factors beyond Neptune, found events that consistently correlated with what he at first thought were planets. Later, his colleague Friedrich Sieggrün added four additional factors.  Both studied in the 'Kepler Circle', an astrological group which sought to preserve only the most precise and reliable of astrological techniques, following the objective of Johannes Kepler, who was both an astronomer and astrologer.  Elements of the Kepler Circle eventually developed into the Hamburg School of Astrology, elements of which are often referred to more recently as Uranian Astrology.

Witte assumed his four transneptunian factors to be planets, as did Sieggrün his four additional transneptunians.  However, not all those working with the total of 8 trasneptunian factors used by Witte and Sieggrün assume that they are planets; positing that they could also be nodes of sorts, or barycenters of asteroidal belts or other astronomical factors revolving around a central point.

Data for the Hamburg School Transneptunians has been fine-tuned over a period of time.  The original data from Witte and Sieggrün is presented here, along with more recent updates based on the calculations of James Neely.  Neely's updated information was used to calculate Ruth Brummund's second edition of the Transneptune Ephemeride (1890-2000) in 1975, her Transneptun Ephemeride 1920-2000, and the Transneptun Ephemeride 2001-2050.  The purpose of the data being given below is not for ephemeris generation, and thus the figures are rounded off.  This data  gives one a general idea of where these factors have been assumed to be located, and can be used to track and match with the increasing astronomical data on transneptunian bodies being verified by recent space technology such as the Hubble Space Telescope.  The numeric data for the Witte and Sieggrün transneptunians also helps in understanding the proportional relationship of these bodies to the Earth, our solar system, and the astronomically-ascertained planetary bodies within our system.

Before the Plutinos were verified by astronomers, critics of Witte's discovery felt justified in discounting Cupido as real since its orbit is so close to that of Pluto that they would have to 'collide'.  Now we know that there are a number of Plutinos orbiting near Pluto, not all have been accounted for yet, and Cupido is logically among them.  Some have also speculated that some of the Witte-Sieggrün transneptunians may actually be the barycenters of planetary or asteroid groups.

Witte's writings from the 1920s clearly indicate that his transneptunian discoveries to be planets. At the end of the 20th century, it was conjectured that the inner bodies may be Plutinos, and that some may be barycenters of collections of astronomical objects.  Witte pointed out in the 1930s that his transneptunians are difficult to spot with normal telescopes, and may require use of infrared-type cameras... logically due in part to their great distance from Earth.  It may be significant to note that those factors verified by most astronomers as full-fledged 'planets' (as opposed to asteroids, plutinos, planetoids, solar-system newcomers, etc.) are of steadily decreasing physical density (i.e. more gaseous) as we travel away from the Sun -- and this affects ready visual detectability.

The following table includes the Neely data, as well as the older figures calculated by Witte & Sieggrün.

These are the comments amateur astronomer Alfred Witte wrote in 1924 and 1925 about the nature and visibility of the Transneptunians:  "The outgoing emanations of the Sun have, at the distance of Neptune, such a low level of density that their vibratory rate reflects as a greenish-blue color.  The greater the distance from the Sun, the finer and smaller these swirling emanations are, according to the law of capillarity (ed.: which, according to Witte, accounted for the correspondence between the color spectrum and planetary distance from the Sun). (Witte 1975, p 220).  "Of the etheric rays which surround the Sun, the smallest particles radiate  outward from the midpoint of our solar system so that, at the distance of Cupido the low-density mass corresponds with a light blue color.  At the next step of the sequence these emanations should consist of even finer particles, and thus at the distance of Hades resemble an indigo blue color" (Witte 1975, p 220), and "Though it is possible that the conjectured planet Cupido, in spite of the faintness of its reflected light, might be sighted with the telescope; one cannot count on sighting the following planet Hades with the telescope, since its indigo blue color is obscured by the color of the evening sky.  The colors of the next two planets, Zeus and Kronos, reflect the vibratory rates of the colors violet-blue and lavender-grey to us on Earth.  Only through photographic exposures made with plates which record ultraviolet rays would one be able to visibly verify these Transneptunian planets ascertained by mathematical calculations." (Witte 1975, p 222)

What Witte did not suspect is that today we have the technology to detect planetary bodies in these regions, and that at the dawn of the 21st century, information from the transneptunian regions is being relayed to the Earth, bit by bit, which may confirm or clarify Witte's observations.  In addition to the fact that astronomically-verified trans-saturnian planets (except the newcomer Pluto) are of increasingly gaseous and subtle composition as we move outward from our Sun, there are also indicators that the outermost transneptunians are might reflect additional light from a neighboring solar system.


¹  "Orbital period" here refers to what is also called the sidereal period, sidereal revolutionary period, or the simply the revolutionary period, depending on which text you refer to.  It is the time needed for a planet to make one complete orbit or circle around the Sun.  The figures to the left for the Witte-Sieggrün Transneptunians are based on the corrections calculated by James Neely in the 1980s; data provided by Ruth Brummund.

²  Pluto is known to have a highly eccentric orbit, and its distance from the Sun therefore varies significantly, from approximately 30 to 50 AU; it periodically crosses over the path of Neptune and the hypothesized path of Cupido, and very close to, if not beyond, the path of Hades.  Some astronomers in recent years even believe Pluto to be more in the "centaur" classification (as are Chiron and Transpluto) than in the "planet" category, and/or to be one of a number of "Plutinos", i.e. a belt of asteroid-like bodies the Transneptunian region.  From this, we can see an example of the rapidly and continually changing understanding of this region of our Solar System.  While Pluto was first recognized as being "discovered" in 1930, conclusions have been drawn about its chemical and atmospheric composition that are still being investigated and significantly revised.  Thus, earlier inferences about the impossibility of the co-existence of Pluto with nearby transneptunians are groundless.  For a detailed summary of recent U S Government data on the Transneptunian regions arriving from space telescopes, see .

³ One Astronomical Unit (1 AU) is defined as the distance from our Sun to the Earth.  Therefore, by looking at the chart, we see that Saturn is 9.5 times as far from our Sun as Earth is; that Pluto is 39.5 times as far from our Sun as Earth is; that Hades is assumed to be 50.7 times as far from our Sun as Earth is; and that Poseidon is supposed to be 83.7 times as far from our Sun as Earth is, over twice as distant as Pluto from our Sun.
