Sirius is a binary system. Sirius A is the highly visible star, but there is a companion known as Sirius B, first described in modern times by the Dogon tribe of Mali (Africa) and subsequently verified by the observational science of astronomers. The Dogon also described a third celestial body with characteristics of a neutron star. While a neutron wouldn't be visible in the same manner as Sirius B, the combined gravitational attraction of a neutron star, a white giant star and a white dwarf would certainly provide the gravitational force needed to keep the Sun bound at a distance of 8.6 light years. In fact, the presence of a neutron star is by no means necessary for the gravitational interaction of the Sun with Sirius.
Historic and mythological descriptions of Sirius provides further insight into the nature of the relationship between the Sun and Sirius. A shaft leading from the Queens chamber of the Great Pyramid of Egypt was -- and still is -- aligned precisely with Sirius. Given the high probability that it was constructed that way, and considering that the pyramids form a star map in and of themselves, it shows how many epochs Sirius has been in a stationary position relative to the movement of the other stars.
When European philosophers first hypothesized that the Earth revolves around the Sun it was a radical and revolutionary idea of that era. Nicholas Copernicus developed the model and scientific explanation by which the Earth revolved around the Sun, and proponents of the model expounded it after its posthumous publication in 1543. The process of overturning the geocentric model of the Solar System, where the stationary Earth was at the center of the Universe, was not an easy venture and came to be known as the Copernican Revolution. Like most ideas that challenge the existing paradigm, it was not well received by most philosophers of the day. This is evident in the following discourse concerning a lecture given by Giordano Bruno at Oxford University for the Polish Prince Albert Alasco in 1583, (verbatim):
"When that Italian Didapper, who intituled himself Philotheus Iordanus Brunus Nolanus, magis elaborata Theologia Doctor, etc., with a name longer then his body, had in the traine of Alasco the Polish Duke, seene [sic] our University in the year 1583, his hart was on fire, to make himself by some worthy exploite, to become famous in that celebrious place. Not long after returning againe, when he had more boldly then wisely, got up into the highest place of our best and most renowned schoole, stripping up his sleeves like some juggler ... he undertook among very many other matters to set on foote the opinion of Copernicus, that the earth did goe round, and the heavens did stand still; wheras in truth it was his owne head which rather did run round, and his braines did not stand still..."
As can be seen by this malicious retort, the best monds of Oxford did not consider the Copernican heliocentric model in the highest regards. Eventually with the development of science and its support of empirical observations, the Heliocentric model was adopted to explain the celestial mechanics of our Solar System.
Certain celestial movements could not be explained by the model however, such as the precession of the zodiacal constellations, whereby the stars associated with the constellations of the zodiac move retro-progressively across the sky over long epochs of time.
In precession there is a retrograde movement, which means that the stars of the Zodiac move backwards in relation to the overall progression of the celestial sphere. So while the Sun is observed to rise in a given constellation of the zodiac at a given date, say the constellation Pisces on the Spring Equinox of March 21st, over time it is observed that Pisces rises sooner and sooner each year. Eventually, after about 2150 years, the Sun is no longer rising in Pisces on March 21st, but is rising in a different constellation altogether, like Aquarius. This is a retro-progression because it is opposite of the apparent direction of the Sun within a single year, where the Sun moves in the opposite direction of the precession through the zodiacal band of stars, so from January to February the Sun appears to travel from Aquarius into Pisces.
This progression is due to the movement of the Earth around the Sun, and not the Sun around the Earth, as was purposed in the geocentric model. However the retro-progression cannot be explained by the movement of the Earth around the Sun, therefore, an additional revolving movement was introduced.
Since it was known that the Earth was tilted on its axis, it was hypothesized that the Earth wobbles around this axial tilt in a precise manner every 26,000 years. This would explain the precession of the Zodiac stars, as it takes about 2150 years for each Zodiac constellation to precede and there are 12 constellations (well there use to be until the introduction of the 13th constellation Ophiuchus into the Zodiac, which is a more harmonious configuration to the natural order) that equals approximately 26,000 years.
Problems with the wobble
By what mechanism is a secondary retrograde rotation of the axis itself induced? The theory that was posited came to be known as Lunisolar Precession [right]. It was hypothesized that torque from the Sun and Moon supplied a force that perturbed the orientation of the axis, causing it to wobble. I call this the "Wobble Hypothesis".
When you take into account all the rotational motions and orbital paths of these three bodies (i.e. the Sun, Earth and Moon) it is staggering to think that a uniform force could be applied to generate a stable enough torque to maintain a 26,000 year periodicity through the precessional cycles.
It should be noted that this number -- 26,000 years -- is rounded off and is not a stable time-line for the precession. The actual precession proceeds with temporal fractionalization , where in measurements from 1900's to 1990 it increased from 25,800 years to 25,920 years. The phenomenon of temporal fractionalization, whereby time accelerates in fractals so that more cycles are fit into shorter periods, was well known to the Mayans and is an intrinsic part of their Calendars, regarded as some of the most accurate measurements of time to this day . Furthermore the interactions of the numerous other celestial bodies of the solar system were not even considered, as well as the oblate geometry of the Earth, and as such the mathematical models have been continually altered in an attempt to manufacture a proper solution.
The history of the lunisolar precession model is one of problems, revisions, and the continuous addition of new inputs. Newtons' original equations did not work. d'Alembert, recognizing the earth was not a rigid body, made the first major changes, and many others since have added and changed dynamical inputs until the values have come very close to fitting the observable of approximately 50.3"p/y [50.3 arc seconds per year is a unit of astronomical measurement, it equals 30 degrees of precession about every 2000 years, 30 degrees being about equal to the diameter of the full moon]. The problem is that while current models are designed to closely approximate a fixed precession observable on a fixed date, the observed rate has been increasing at an increasing rate over the long term (100+ years), something that current models have been unable to predict. As predictability is a litmus test for the validity of a theory, the lunisolar theory is now undergoing increased scrutiny. 
This information by itself raises serious questions about the validity of the "Wobble Hypothesis". However the major flaw of this hypothesis comes from an examination of the static position of the star Sirius in relation to precession and its historical utilization as a marker for time in the Sothic Calendar of the Egyptians.
From Africa, where the Dogons live, the star Sirius disappears below the horizon and is out of sight for a couple of months; then it appears again on the morning of July 23, when it rises about one minute before the Sun. It appears bright ruby-red, just above the horizon, almost exactly due east. Sixty seconds later the Sun emerges. So you can see Sirius for just a moment, then it's gone. This is called the helical rising of Sirius, which was a very important moment for most of the ancient world, not just for the Dogons and Egypt.
This is the moment when Sirius and the Sun and the Earth are in a straight line across space. In Egypt, almost all the temples were aligned with this line, including the gaze of the Sphinx. Many of the temples had a tiny hole in the wall somewhere; then there would be another wall and another, going into some dim inner chamber. In that chamber there would be something like a cube or Golden Mean rectangle of granite sitting in the middle of the room with a little mark on it. At the moment of the heliacal rising of Sirius, a ruby-red light would strike the altar for a few seconds, which would begin their new year and the first day of the ancient Sothic calendar of Egypt. 
The periodicity of the helical rising of Sirius was such that the Egyptians based their calendar on it [right]. Every year for millennia the appearance os Sirius coincided with the flooding of the Nile, an event that remarakbly still happens to this day.
This fact alone betrays the blatant flaw in the current consensus model for the precession of the Zodiac. With the "Wobble Hypothesis", the Zodiac stars aren't actually moving; they are fixed in place. The apparent retrograde motion is only the result of the transient shift of the equinoxes. Therefore it receives it's much more common and well known description as "the Precession of the Equinoxes". In this consensus model, the equinoxes are occurring at different locations within the Earth's orbit around the Sun, and since they are occurring at different locations there is a different backdrop of stars.
The equinoxes and solstices are a function of the 23.6° tilt of the Earth's axis. When the tilt is facing the Sun, the Northern hemisphere is in summer because it is receiving more sunlight and there are more daylight hours -- the days are longer and the nights are shorter. When the tilt is away from the Sun, the Northern hemisphere is in winter. This is opposite for the Southern hemisphere. The midpoints between these two extremes are the equinoxes, where the length of day and night are equal.
The equinoxes retrogress because the tilt is changing its orientation to the Sun as it wobbles about. This causes the equinoxes, as well as the solstices to occur in different locations in the Earth’s orbit [right]. The problem is that if the equinoxes and solstices were occurring at different locations then Sirius could not have a precise helical rising every July 23rd from the latitude of Egypt!
All of the equatorial backdrop of stars would retrogress with the wobble of the Earth, and thus Sirius would have a helical rising that regresses throughout the Year, occurring at all different seasons throughout the 26,000 year cycle (see figure 5). The only stars that would remain relatively fixed are those at the poles, although they would still have minor perturbations themselves. But his is not what is observed. As Jed Buchwald, professor of the history of science at Caltech, states:
"Sirius remains about the same distance from the equinoxes -- and so from the solstices -- throughout these many centuries, despite precession" .
The Helical rising of Sirius in the summer, showing how the Sun and Sirius become aligned along the horizon of the Earth as it rotates into the light of the Sun. Similarly the Sun and Sirius are aligned in the winter as well, however, because Sirous is on the outside it appears directly above the Sun as it rises in the winter. This is the source of the Star of Bethlehem. It is the star Sirius.
The Solstice would occur at A, but because of the retrograde wobble of the axis (b), winter now occurs at C.
Figure 5: The wobble of the Earth's axis causes the seasons to occur at transient locations in the Earth's orbit during the cycle of the precession of the Zodiac. If the precession were due to the wobble, then Sirius would shift with the equatorial stars as well, and occur in a different season corresponding to the specific alignment.
These inconsistencies are resolved in the new precessional paradigm.
First off, the seasons do not regress with the precession of the Zodiac. They remain fixed in their location relative to the Sun. But not loci-static in the orbital revolution around Sirius. That is, seasons occur at different positions relative to Sirius (see figure 6). However the Sun's revolution around Sirius is so eccentric and long that perturbations in the position of Sirius are not perceived until the Sun reaches apastron. Apastron is the point in a star's orbit where it is furthest from its orbital companion, this is intrinsic to the nature of elliptical orbits. As the Sun revolves around Sirius, the zodiacal constellations shift location and appear to have a retro-progressional movement across the sky over epochs of time.
Figure 6: The Sun orbits around Sirius, and as it does so the backdrop of stars forming the Zodiac constellations change location. However the location of these seasons occur at the same position within the Earth's orbit around the Sun.
As the Sun passes through the apastron points approximately every 13,000 years, Sirius would indeed appear to have a precessional migration across the sky, until eventually the heliacal rising would occur in the winter (see figure 7). And this is fine, because it does not violate any historical recordings of the behavior of Sirius. In fact, a review of the highly advanced Babylonian astronomy shows that this was actually described.
The term Nibiru is well known, and equally misunderstood. The Babylonians used it more as a descriptive term than a name representing a specific object. In Babylonian Astronomy it was used to describe a star -- not a planet -- as can be seen in the following examples from translations by Horowitz : The Helical rising of Sirius as the Sun orbits it. Since the location of the solstices and the equinoxes are occurring at the same location within the Earth's orbit around the Sun, the helical rising is switched when the Sun reaches the opposite point in its orbit.
* He [Marduk in context] set fast the position of Nibiru to fix their [the stars] bounds."
*"...let Nibiru be the holder of the crossing place of the heaven and of the earth."
*...the red star which stands in the south after the gods of the night [the stars] have been finished, dividing the sky in half, this star is Nibiru, (i.e., Marduk)." (note it's a red star, and this is often how the Ancients described Sirius)
* "Nibiru is his [marduk's in context] star, which he made appear in the heavens ... The stars of heaven, let him [Nibiru] set their course; let him shepherd all the gods like sheep."
What can be seen clearly here is that the term nibiru is being used to describe a star, that this star sets the course of the other stars, that is to say that it is the source of their precession, and that it is the crossing point.
It is my supposition that Nibiru is referred to as a "crossing point" because when the Sun passed apastron and began its opposite revolution, Sirius would cross the sky. Not only did this crossing of Sirius mark the turning point in the Sun's orbit, but also the turning point in the Yuga cycles.
The new Sun-Sirius system model satisfies the observational behavior of Sirius and the constellations of the zodiac as they regress throughout the great cycle of 26,000 years. There is no need to introduce a "wobble" in the Earth's axis, induced by the action of 9 other celestial bodies -- a theory which is just a relic from a time when the motion of the Solar System was not yet conceived.
It would be sagacious not to place Sirius at the center of the Solar System, for in a fractal system there is no true center. The fractal nature of the Universe engenders its self-arrangement, or more apropos, the Universe is a holofractal graphic system . Therefore there are many nested orbital interactions, going out as far as the local cluster of galaxies, which themselves have a focal point.
This is nothing new. Previous civilizations understood celestial mechanics at an advanced level, and the mathematical precision of their astronomical observations is a testament to this . The reason why the Egyptians and many other civilizations of that era used Sirius as their marker for the passage of time is because they picked the most stable object as their reference point.
We choose the Sun as our reference point, and this is obviously highly inaccurate. Every 4 years a day has to be added to keep accurate time. But even Sirius was not accurate enough for the "Keeper's of Time", the Mayans. With their remarkably advanced astronomy they quickly detected the inaccuracies in using Sirius as a marker for the passage of time, and switched to an even more accurate cycle involving the Pleiades. There is however an even more stable reference point than the Pleiades and that is the Galactic center, which from the perspective of our galaxy is the ultimate center of rotation.
And indeed the Mayan's chose the Galactic Center as a reference point to mark the passage of time, which is evident as the Mayan Long Count ends with the galactic alignment of the Solar System on December 21st 2012. Therefore, the idea that the Earth orbits the Sun, or that the Sun orbits Sirius, or that Sirius orbits Alcyone and that Alcyone orbits the Galactic Nucleus, is not revolutionary -- it's just a rediscovery of lost knowledge.
