Previous Analysis


Beyond a reasonable doubt, the ancients were aware of an additional Jupiter like body in our solar system, one that most of our current astronomical community is totally unaware of. However, some powerful members of this community were aware of this ancient knowledge and appears to have combined it with intelligence gained from extra-terrestrial aliens contacts. Apparently, there may be an ultra-tiny brown dwarf in our outer solar system. The Pioneer, Voyager, IRAS satellite and possibly even the Hubble space telescope were constructed to find and observe this half Jupiter sized brown dwarf star.

While there is no proof that others have ever found this solar body, this web site has been able to deduce it's mass and orbital parameters. Moreover, many of these values have been verified beyond a reasonable doubt. This body has been dubbed Vulcan because a theosophist, Madam Blavatsky, already named it that and described how it affects the formation of mankind's great avatars.

Physically, however, Vulcan's orbit is such that it draws small bodies from the Kuiper Belt, and casts them into comet like orbits. Sometimes these objects pass through the solar system in Sun grazing orbits. Then they break up forming meteor or comet swarms. At least five such swarms have been identified. Often, some members of these swarms impact Earth when they pass through the inner solar system. More than thirty such impacts causing massive weather changes have been identified from tree ring and ice core data spanning the past 15,000 years.

Venus may have been hit by just such a large fragment only a few million years ago. The magnitude of the impact had the result that its surface was melted and reformed. This event offers support for Christ's prediction that a similar catastrophe could happen to Earth. But before that happens, Earth may be subjected to another impact (before ~2160 AD) starting a new Ice Age. After that, (~3800 AD) Earth and a diminished and weakened mankind may suffer a similar fate, making Earth uninhabitable. The video below offers a realistic scenario depicting how this final event could unfold.

Meteorite Collision



Vedic Prophecies have long held that the Sun has a 'dark companion' and the Bible Code, written about 3200 years, ago not only contains references to it by name but associates it with comet/asteroid impacts. Madam Blavatsky even refers to how its presence astrologically influences avatars like Christ and Buddha.

A Jovian sized Vulcan was known to the ancient Akkadians of the third millennium B.C. Not only was it known, but they also knew of planets Neptune (that cannot be seen with the naked eye) and the barely visible Uranus. Figure 1 shows the Akkadian seal containing an image of Vulcan and the four Jovian planets, Jupiter, Saturn, Uranus and Neptune (courtesy of the seated god Ea - a Cenos astronaut from the Proxima Centauri star system). Note the size of Vulcan is between that of Saturn and Jupiter. Almost anyone can envision the Sun and these five solar bodies depicted in the Akkadian Seal.

Figure 2 shows a mathematical fit of the Sun and Jovian's diameters as measured from the Akkadian Seal vs. their known masses. The quality of the fit (0.997) of the straight line proves, beyond any doubt, that the 'ancients' were both aware of these planets and their relative masses compared to the Sun's. Further, it also implies that there is another Jovian like planet in our solar system (our Vulcan) of 141 +/-35 Earth masses. Similar Vulcan masses have been deduced by other means; 166 Earth mass and [333,000(Sun mass in Earth masses)] X [ 0.35 Earth Orbit radius from the Sun (Bary Center)]/[ 447.6 - 0.35] = 261 Earth Mass.

Figure 2. A Mathematical Fit Of The Depicted Diameters Of The Jovians/Sun Vs. The Logarithm Of Their Masses.

Newton's 'Philosophia Naturalis Principia Mathematica' published 5 July 1687 offered the first modern day estimates of relative masses for the known giant planets, the Earth and the Sun. So one must wonder where the ancient Akkadians got the concept of mass depicted on the Seal. Further, the inclusion of Uranus and Neptune on the Seal suggests that the source of this knowledge must be someone else. Most likely, this information came from extra-terrestrial alien contacts because only they would have the technology to deduce this information at that time.


There are more recent references to this dark companion from those "extra- terrestrial alien" sources. Dr. J. Allen Hynek (Astronomer):

Civilian scientific consultant to the U.S. Air Force (1948/49-1969) i.e. 20 years. He began as a debunker of UFO sightings, however he discovered there was what he felt were a significant percentage of these reports which he could not explain. He became convinced they deserved further study by the scientific community.

seemed to think that some of these alien contact reports were valid and they are. Perhaps this was one that caught Hynek's attention.

Figure 3. Extra-terrestrial Alien Description Of Our Alphabet And Solar System.

A well circulated, but unpublished, case occurred on 6 Oct. 1974. The individual was invited on-board a saucer. Figure 3 is the Invitee's description of the alien's interpretation of our alphabet and a description of our solar system. Our planetary symbols were employed by the aliens, but they may have been deduced years before they left on their long journey to our solar system. The first three alien symbols, 12V, translates to G2V. The Sun's recognized astronomical characterization is that of a G2 main sequence spectral class V star.

Three other solar objects are indicated, one above and one below the string of planets and a final one at the end. Two (* and phi) appear out of the ecliptic plane. One of these may be Eris whose inclined orbit indicates that it (and 2000 CR105) are objects 'captured' by the Sun. While the I symbol denotes a super-giant star, if the Invitee failed to notice a V (i.e. as in IV) a sub-dwarf star may have been indicated. The IV is (incorrectly) associated with brown dwarf stars, but perhaps this was the only designation available to the aliens at the time. The Invitee was also told that the asteroids (Maldek) resulted from an exploded planet, a view since popularized by a well known Naval Observatory astronomer.


It appears that someone in the government/NASA decided that a search for this distant planet or brown dwarf was a worthwhile undertaking.

Not only were the Pioneers sent out to try to detect its gravitational influences on the spacecraft, but the Voyagers were sent out to refine its location.

Figure 5. Locations Of Pioneer And Voyager Space Probes.

Figure 5 shows that the Voyager probes (launched 1977) bracket an object (a Brown Dwarf?) roughly located by the Pioneer probes (launched 1972 - 73). Table 1 shows that one of the first reported IRAS (Infrared Astronomical Survey) Satellite objects, IRAS 1732+239 - thought to be our Vulcan, is in the nominal direction of Pioneer 11. Pioneer 11's radio transmitter (conveniently?) 'failed' when it was about the distance of Pluto's perigee (30 AU).

Figure 6 shows a 1983 NEWS report of a heavenly body almost as large as Jupiter, or possibly a protostar (brown dwarf) discovered 50 billion miles away.

Figure 6. A NEWS Reports Of A Jovian Sized Planet Being Found.

The object may have been IRAS Object 1732+239, one of the first nine unresolved objects first nine objects found by the IRAS Satellite. The resolution of the other two IRAS objects that were initially unknown (1703+049 and 1712+100) appear to have been reasonably well accomplished. The image for IRAS OBJECT 1732+239 showed multiple objects in the error box. Notice in Figure 6 that there may have been an attempt to 'off-ramp' others who may be interested in this object by claiming that it was in the constellation Orion.

Sitchin noticed a fifth Jovian like object (our Vulcan) on the Akkadian seal, but Hynek (and the 1974 aliens) considered it to be a brown dwarf like star. The IRAS satellite could detect nominal range and possible motion of a ~50 billion mile distant infrared object in our solar system. That is why multiple acquisitions of an IRAS object were required to confirm its possible existence in our solar system. A comet would be too small to be detected unless it were truly a giant planet sized one. And a dust shrouded galaxy would not move, but its infrared output could possibly vary thus giving a false reading. The NEWS article proves that the IRAS team was at least aware of the fifth Jovian sized planet depicted on the (alien derived?) Akkadian Seal as well as the alien concept that it could be an un-ignited stellar object (e.g. a ultra tiny brown dwarf). This also proves that a select group of astronomers were also privy to extra-terrestrial alien intelligence concerning the structure of our solar system. Our ASTRO- METRICS concept considers it to be the binary companion of our Sun and the instrument necessary to form our planets. But this does not prove that they discovered such an object in our outer solar system.

Sitchin noticed that some astronomical object (in a comet like orbit) appeared in the sky's of Earth several thousand years ago and assumed it was this large Jupiter like object. But such a passage would perturb the orbits of the inner planets, likely even ejecting them. Given the circular nature of most of the terrestrial planets, that clearly has not happen. But what astronomers have long known is that an icy comet impact may have caused Noah's flood (first suggested by Sir Isaac Newton's assistant, William Whiston)


We believe the brown dwarf star depicted in the Figure 4's Science Digest article to be Madam Blavatsky's Vulcan. Her description of it being "The Forge Of The Avatars" or "The Solar Logos" requires Vulcan to be star like. Astrologer Max Heindel described how the Moon plays a similar function for humans. We have regard the Earth/Moon system to be a double planet. Thus, there is a mechanism in place to deduced Vulcan's orbital parameters. See Table 2.

Table 2 shows Vulcan's orbital parameters. Vulcan's Aphelion is 41.6 billion miles (448 AU) vs. Hynek's 50 billion. Forbes (1880) used comets aphelia to predict a similar orbit. Stars pass within 2000 AU of the Sun over the solar system's life and would eject planets more distant than 47 billion miles (500 AU).

The reclassification of Pluto and Eris as dwarf planets also makes one wonder if they could be the planets of a brown dwarf star. This is especially true of Eris since its orbital inclination is about 44o (just a few degrees less than Vulcan's 48.4o. Kenyon and Bromley (originally posted by Harvard) say that only the detection of objects with orbits inclined 40o or more from the plane of the ecliptic will prove the existence of 'alien' planetoids. This may be why the existence of 2003 UB313 (AKA Eris) was kept secret. In other words, Eris' 44o orbital inclination associated it with a brown dwarf star, i. e. Vulcan.


Vulcan draws in Kuiper belt objects that fragment into meteor or comet swarms if they pass near the Sun. Figure 7 shows how these Vulcan related swarms move about the Sun.

Figure 7. Vulcan Related Meteor Or Comet Swarms.

These swarms are labeled A' & A and B' & B respectively. A rogue swarm C is also present. Their periods (~3313 years) are about are two thirds that of Vulcan's, but vary slightly due to Vulcan's distant presence. The 3:2 resonate orbit means that the comets orbit the Sun three times every time Vulcan orbits it twice. Thus, for an interval of every three comet revolutions, or two Vulcan revolutions, the celestial geometry modifying the periods of the distant comet swarms is the same as before. This interval is theoretically 9938 years, two times Vulcan's theoretical 4969 year period.


The comet impact threat was known to the Egyptians well before the time of Christ. However bot Christ and Sir Fred Hoyle probably offer the most outstanding warnings. The Bible is full of warnings of comet or asteroid impacts, especially from Christ as found in the New Testament. Clear text Bible predictions speculating on impacts have been interpreted as follows:

"Starting at the end and work forwards, the last cataclysmic event is when the Earth is renovated by fire. It is discussed in 2 Peter 3:5-13 and Revelation 20:7-15. The Earth is turned into a sea of fire and lava. There are no longer any oceans. This event could be cause by a large impactor 100- 200 miles in diameter. The Meteorite Collision video offers a good illustration of such an event.

Before that happens there will be a millennium, a thousand years, of peace. Revelation 20:1-6 - God made a promise to the Jewish people, during this time he will begin to fulfill it. Before that there is a Great Tribulation. This event is discussed in Matthew 24:21, Revelation 8:5-13, Revelation 6:12-17, Revelation 16:17-21 and Revelation 18:8-10,21 to name a few. The damage falls in line with the damage that would be created from an impactor in the 2 - 3 mile diameter range. Across many cultures, dragons have been symbolic of comets. As a result, if the damage during the Great Tribulation, was done by an impactor, it is somewhat natural to believe that the impactor would be a comet."

A few million years ago, such an event happened to Venus. See: What Would Happen If A Massive Oort Cloud Comet Stikes Earth? Answer: Venus
"After several million years, the planet would cool down and a crust would form. The crust creates an insulation barrier between the hot magma and the atmosphere. Surface temperatures would drop below 1,000o F. The average temperature at the surface of Venus is 865o F."

The recently deceased Royal Astronomer, Sir Fred Hoyle, has likewise warned us of such disasters. He proposed that meteors (or comets) strikes are responsible for both the rapid onset and termination of Ice Ages as well as the variations of global ice levels found in the Pleistocene. This is exactly what a 2 to 3 mile in diameter impactor would do. Specifically, Hoyle said:

"Together with disease, the next ice age ranks as the biggest danger to which we as individuals are exposed. The next ice age is not a specific problem of the distant future. The causative agent, the strike of a giant meteorite, could happen at any time.

The risk of the next ice age is not just the biggest of the risks that we run. It is a risk that would hopelessly compromise the future. Besides wiping out a considerable fraction of those now alive, it would leave a wan, grey future from which the survivors and their descendants could do nothing to escape. It would be a condition that might last 50,000 years or more, a future in which the prospects for mankind would be much less favourable than they are today. This is why our modern generation must take action to avoid catastrophe, an ultimate catastrophe besides which the problems that concern people, media and governments from day to day are quite trivial."

Mother Shipton, Nostradamus, the Biblical Zechariah and a host of minor prophets have likewise forecast impending comet impacts. What's worse, Nostradamus' predictions end in the year 3797 AD implying that mankind likewise ends then. Apparently, should the impact of a giant meteorite or comet happen before 2160, the population of the Earth would be so decimated that it would be unable to prepare for the 'Venus like' cataclysmic event predicted by Christ.

Current warnings have even come from what appears to be extraterrestrial alien sources as late as 1995. Figure 8 contains an image of Crop Circle T367. Note that the planets depict a planetary positions that seem to relate to late February 2007 and that the Earth appears missing from its orbit seeming implying that it will be destroyed by one of the objects labeled 2 - 5 (comets or meteors?). Such objects would not physically destroy Earth, but they may just cause a major change to its habitually for mankind.

Figure 8. Crop Circle T367 - The Solar System - Indicates Four Threatening Impact Times.

It is interesting that in this crop circle, the Sun is offset from a cleared central region. The offset is in the opposite direction of IRAS 1732+239. Considering Vulcan to be near aphelion, 448 AU, simple mathematical projection implies it is about half the mass of Jupiter - 160 Earth masses. Vulcan's high inclination is not alluded to here implying that this crop circle is to be considered a 'cartoon' and not a 'photograph' of the physical situation. Four threat periods per year have been identified for the years after 2007.


Humans became sentient about 55,655 to 55,680 BC near an Ice Age thermal minimum. Then it got colder. The climate did not begin to warm up until 15,000 years ago.

Table 3 illustrates that Earth has been the victim of many impacts in the recent past. Major comet/meteorite impacts cause significant weather changes and cause the collapse of civilizations. The most notable events are Noah's Great Flood (~3,195 BC) and the Atlantis disaster (~9,703 BC). The comets/meteorites may not be visible until they hit the atmosphere as their volatile ices may have been cooked away during their many passes around the Sun.

Comet impact generated climate changes offer indirect evidence that verifies Vulcan's theoretical period. The 3:2 resonance means an interval of two theoretical Vulcan (4969 year) periods is required to maintain the same celestial geometry's impact on the swarms otherwise Vulcan's gravitational force slightly changes the swarm's period. The 9938 year interval has been measured to be accurate to within a year for two A Swarm Cluster 1 (A:Cl-1) impact events. These are spaced exactly two Vulcan periods apart. The measured value is found to be 9939 years. However, the second event was a small one as the major meteorite/comet appears to have hit during the earlier event. A similar value of 9942 years is measured for the B:Cl-1 cluster that initiated the Younger Dryas weather change event.

Indirect evidence is also available from the orbital period of comet 2000 CR105. CR105 is a member of an exclusive club containing only a few distant comets whose perihelion's (far-points) are too far away from Neptune to be influenced by it or any other commonly know solar planet. CR105 orbit offers the elusive astronomical evidence that is tantamount to revealing Vulcan's existence.

Vulcan's mass only slightly changes the average period of CR105 over three orbital revolutions. Including/excluding Vulcan's mass and orbit, CR105's average period is 3319.3 years/3316.7 years respectively.

Multiplying CR105 average period by 3/2 gives Vulcan's period of 4979.0 years, only ten years off the theoretical 4969 year value. Moreover, other distant objects, like 2001 FP185 (3433.7 years) and 2002 GB332 (3234.2 years), appear to be in a similar 3:2 resonance and 1999 DP8 (1246 years) in a 4:1 resonance with Vulcan.

Weather changes at nominal ten thousand year intervals induced by impacts of fragments from the A:Cl-1 and the B:Cl-1e swarms' cluster along with the estimate of Forbe's planet's period and the CR105's average orbital period offer a ways to verify Vulcan's orbital period. These three different means using four different independent measurements can be statistically combined yielding:

Vulcan's Combined Measured Period = 4969.3 years +/- 8.14 (one sigma) years.

Vulcan's theoretical period obtained from the Blavatsky's Theosophy is:

If Vulcan is at the IRAS point:
Vulcan's Theoretical Period = 4969.0 years +/- 5.7 (one sigma) years.

If Vulcan is nearby (e.g a typo was made recording the IRAS point):
[Vulcan's Theoretical Period = 4972.0 years +/- 27.35 (one sigma) years.]

It is statistically certain that the combined measured periods is within 97.6% of Vulcan's theoretical period if Vulcan is at the IRAS point employed, and 92.4% if it is not. Any probability > 40% means that the two physical quantities are related.

There have been at least 36 weather changing impact events over the last 15 thousand years. A recent one, around 2345 BC, claimed more than half the population of the world. Even worse catastrophes may have occurred earlier than three thousand BC.

The climatic change data provided by the Center for Ice and Climate, offers data showing at least five major weather changes about ten thousand years ago. With the knowledge of Vulcan's period and the 3:2 resonance structure of the meteor/comet swarms, an accurate estimate can be made of when Earth is next at risk. These calculations imply that we are currently living in a time when dramatic weather changes could very rapidly occur - usually Global Cooling Events.

The danger periods over the next 150 years are thought to be associated with the B swarm. If these meteor/comet clusters remain potent weather changers, the odds are that a significant weather changing event will occur before the close of 2017. Noah's Great Flood and the Atlantis Catastrophe really happened, artifacts from these events (like Noah's Ark) have been found and the times they happened have been pinpointed. The elite who rule our world are nervous that their civilization could disappear in an instant.

Related impacts/weather changes may already be underway. The 8 October 2009 Indonesian 10 meters wide meteor exploding in air with the force of 50,000 tons of TNT could be the first major strikes from the returning first cluster of the B-swarm. Significant weather changes have appeared since then.

In 2010, comet fragment explosions may have caused great concern. The WISE Infra-red comet and asteroid detector that was launched in December 2009 was waiting for them. The WISE Infrared Space Telescope is:

"really good at finding the darkest asteroids and comets" like "dark asteroids that may be former comets that have long since had all the ice vaporized from their exteriors, leaving them with inactive surfaces that no longer shed dust to produce tails."
WISE's mission ended late October 2010. Dark comets warmed by the Sun results in an increase in their visibility for 5 months (~2.8 AU) before they threaten Earth. Comets near or beyond Jupiter's orbit are generally stable, as water ice is unaffected by the Sun's warmth beyond about 5 AU. Note that pure, clean, white snow or ice is stable as far in as 2.7 AU, in the middle of the Asteroid Belt, but normal comets have significant quantities of dust and dark materials such as hydrocarbons which increase the absorption of solar radiation.

There was concern that the mid November 2010 comet fragment (e.g. meteor) atmospheric detonations over the North Atlantic and Chinese landmass could have lead to much colder global winters. These fragments are thought to have come from space debris that first grazed Earth circa 5 to 7 September, impacting Colombia and Brazil. The impacts of these meteorites apparently injected enough cosmic dust in the atmosphere to cause a Massive Cooling Event in northern Europe and southern China. Just before the 12 November G20 meeting of that year, two Sub launched ballistic missiles were launched off both the East and West Coast of the USA. They were soon determined to be of foreign origin, most likely Chinese. This threat of nuclear war has continued with unpublicized, but verified, military nuclear detonations in Syria (2013) and in Yemen (2015).

The threatening meteorite fall period has been reduced to one for 2015 and it is expected to continue for 2016 through 2017 with 2016 being the most dangerous year. However, utilizing just Vulcan's measured period and measured uncertainties, that dangerous period could be between 2021 and 2023 instead of 2016 and 2017. Collateral data suggests the 2016-2017 period is more likely. This bombardment activity could involve major massive objects.
