Planet X and 2012: The PseudoAstronomy (or Just Plain Wrong Astronomy) About a Galactic Alignment


One of the many “theories” behind the 2012 doomsday scenario – but one of the few that does not involve the “Planet X” (at least in sum and substance) is the idea that on December 21, 2012 (sound familiar?), the sun and/or solar system will come into alignment with the galactic plane or center of our galaxy and cause bad stuff to happen. There are several different proponents of this, including John Major Jenkins and Brent Miller, the latter also linking it with a Planet X (discussed in future posts).

Note that most of the numbers/values in this post come from the book, Galaxies in the Universe (an undergrad/grad text) by Linda Sparke and John Gallagher, © 2000.

A Crash Course in the Sun’s Orbit

We are on Earth. Earth orbits the sun (a star). The sun orbits the Milky Way, our galaxy. Just as Earth orbits within the solar system but still orbits the solar system’s center of mass, the sun orbits the Milky Way’s center of mass but is still inside the Milky Way (that’s a complicated way of saying that we are neither at the center of our galaxy nor at the edge).

As Monty Python’s song states, “The sun and you and me, plus all the stars that we can see, are moving at a million miles a day, … the galaxy we call the Milky Way. Our galaxy itself contains a hundred billion stars, … we go ’round every 200 million years.” The numbers are reasonably accurate, though our orbital period is more recently calculated to be approximately 250 million years to make one complete ellipse around the center. Notice that I said “ellipse” for the orbit. This is correct, but to very good approximation, the stars out by us are mostly on nearly circular orbits.

Besides just orbiting in a single plane (as in like a flat piece of paper), stars also oscillate through the general gravitational plane of the galaxy. They generally stay within the “thin disk” that contains 95% of the stars, but this thin disk is on the order of about 1000 light-years thick (though, compared with the diameter of the galaxy being 100,000 light-years, this is still pretty thin). Our sun is one of those stars that does oscillate through the gravitational central plane of our galaxy.

The Sun’s Current Position and Velocity

Today, yesterday, and tomorrow, the sun does not lie in the galactic midplane, but it is about 35-70 light-years “above” it (since there’s no “up” in space, you could also say it lies below it). It is also currently still traveling “upwards” in the direction of the North Galactic Pole at a rate of 7-8 km/sec.

It is also not on a perfectly circular orbit relative to the plane of the galaxy, moving presently inward at a rate of 10-11 km/sec. Its rotational velocity around the center of the galaxy is about 200 km/sec.

I should also note that the center of our galaxy, the supergiant black hole known as Sag A* (pronounced “Sag A-star” or “Sagittarius A-star”), is the celestial coordinates 17 h 45m 40s RA, -29° 00′ 28.00″ DEC. What those actually mean is unimportant at the moment, just keep it in mind.

First of Two Ideas of the Galactic Center/Plane and its Relation to 2012

There are really two main premises of what will happen in or around 2012 in regards to the plane of the Milky Way. The first was popularized by John Major Jenkins back in 1998, and it deals with an apparent alignment, as viewed from Earth. To quote him:

Amazingly, the center of this cosmic cross, that is, right where the ecliptic crosses over the Milky Way, is exactly where the December solstice sun will be in A.D 2012. This alignment occurs only once every 25,800 years. [page XXXIX, italics are his]

The bottom line of my theory is that the ancient Maya chose the 2012 end-date because this is the date on which occurs a rare alignment of the solstice sun with the Galactic Center. [page XLI, italics are his]

The Long Count calendar is a galactic calendar because it pinpoints a rare alignment with our Milky Way Galaxy, due to occur in A.D. 2012 – a date written as in the Long Count. [page 105]

However, he gets the dates wrong, and corrects it in a later book published in 2002:

Early on in my research, I recognised that the solstice-galaxy alignment would occur around 1998 or 1999. This was based on precise astronomical concepts (e.g. galactic equator and solstice colure) and a rough estimate I made with EZCosmos astronomy software, confirmed by the calculations of European astronomer Jean Meeus and the US Naval Observatory. I’ll have more to say about this precise timing in chapter 21, but suffice it to say two things here. First, the fourteen-year error between 1998 and 2012 amounts to less than one-fifth of a degree – a tiny sliver of the width of the full moon and thus negligible, considering it is a forward calculation in precession of at least 2,000 years. Second, the sun itself is one-half a degree wide, so an alignment zone between 1980 and 2016 must be allowed, thus embracing the 2012 end-date. [page 12]

His math is a little wrong – 0.2° is actually 40% of the width of the full moon, not a tiny sliver, but I’ll forgive that for the sake of just presenting his argument.

Journalist Lawrence Joseph expanded upon this in his own book, Apocalypse 2012: A Scientific Investigation Into Civilization’s End. In a statement to USA Today, he said:

Part of the 2012 mystique stems from the stars. On the winter solstice in 2012, the sun will be aligned with the center of the Milky Way for the first time in about 26,000 years. This means that “whatever energy typically streams to Earth from the center of the Milky Way will indeed be disrupted on 12/21/12 at 11:11 p.m. Universal Time,” Joseph writes.

Why This Is Wrong

Jenkins’ premise is actually somewhat correct in the sense that, yes, the sun will be somewhat near the plane of the galaxy as seen from Earth around the winter solstice in 2012. But not anywhere near Sag A*. And there’s nothing mystical about the plane of the galaxy … in fact, the sun passes “through” it as seen from Earth once a year. It just so happens that for the last ~300 years through the next ~300 years, this will happen to coincide with mid-December – winter solstice in the Northern hemisphere and summer in the Southern. There is really NOTHING special about this other than New-Age woo and mysticism.

The Second of Two Ideas of the Galactic Center/Plane and its Relation to 2012

The second idea is that our solar system will actually pass through the plane of the galaxy on December 21, 2012 — instead of an apparent alignment, this version of the claim is that it is a physical alignment. I’m sure others believe it, but the person I have heard this from is Brent Miller of the Horizon Project. Now, just from a practical standpoint, I want to make this point: Brent and the folks at the Horizon Project claim to have incontrovertible proof that Earth will suffer considerably in 2012 due to various things. However, they don’t provide that information on their website (thehorizonproject.com). Rather, they want you to order their DVD for “only $24.95 each!” Now, capitalism is great and all that, but you would think that if they really want to help people survive this thing when they literally claim that up to half the world’s population will die within a day, then they’d be putting out as much free information as possible.

Note that the material and quotes in this section of the post come from Miller’s interview by George Noory on Coast-to-Coast AM from November 10, 2008.

Anyway … their idea is based on a few major false premises. Their scenario is that our galaxy has a central, massive black hole (this is true). Stars oscillate up and down through the plane of the galaxy (this is also true, as I explained in the beginning of this post). This black hole sends out gravity waves (this is predicted by Einstein, but has never been proven). These gravity waves radiate along the plane of the galaxy, creating a “dark rift” zone that is filled with asteroid-sized dust material (this is where it starts to get … incorrect would be the most polite term, or perhaps unproven and unlikely). In addition to being populated by this potentially dangerous material, it has “a very very large intense gravitational field to it, and it takes about 20 years for our planet and the solar system to pass through it.”

Miller makes many claims as to the effects that crossing through this “dark rift” would have on Earth, the bulk of which is called a “pole shift” that I will address in a future blog posting in this series on Planet X and 2012. For the purpose of this post, I am solely going to address his mechanism for doomsday, which is us passing through this “dark rift.”

Why This Is Wrong

First off, keep in mind that this is the entire mechanism for all of Miller’s doomsday predictions (that will be addressed in a future post, as the “pole shift” topic is quite extensive and has its own branch of pseudoscience surrounding it). Consequently, if I can show that his entire mechanism is flawed, then it should cast serious doubt upon his predictions.

And, I can do that fairly easily by referring to the data in the second section of this post: The sun right now is above the midplane of the galaxy by 35-70 light-years, and it’s still moving away from it. It is NOT, as Miller claims, currently in the middle of a 20-year process of moving through this midplane. It is far from it. And, if he has actual data (as in real science) to back up his claim of the sun’s position in the galaxy, then why doesn’t he publish it in the scientific literature? If nothing else, this should make someone seriously question his mechanism, and hence his claims. And ask for actual evidence that can be independently tested.

There’s another reason why this is wrong. The galactic midplane is not this abrupt region of increased gravity. This is a common misconception in astronomy, that galaxies are “solid” objects. All the midplane is is a non-pysical, mathematical 2-D plane where if you add all the gravity from the material below it and above it, then you get the largest possible value. Go a little above it, and there is more mass below you that will pull you back down (eventually). Go a little below it, and the reverse happens.

It is true that, simply by a “settling” of material over time, there is a greater density of stars and gas and dust the closer to this plane that you get. And there’s less as you get farther away.

A reasonable way to think of this is like a valley, or a gently sloped, shallow bowl. If you’re near the top of the valley or the rim of the bowl, then you are going to get pulled down towards the center. And then your momentum will carry you past the center, and you’ll climb back up the other side. And when your momentum runs out, you’ll fall back down towards the center, and this cycle will repeat.

What Miller wants to throw in there is effectively a brick wall … or perhaps a wall of molasses. In his scenario, when you get to the center, you hit that wall and will be affected by something that only exists in the center of the bowl (or valley). What I am saying is that the galaxy is not built that way, there’s no wall, no “dark rift” no “very very large intense gravitational field” to the central few hundred billion kilometers that’s filled with Planet Xs and asteroids and other dangers that will cause doomsday to happen in the neighborhood of 2012.

Final Thoughts

After reading over this post, I realize that some of the ideas are not laid out quite as extensively as I usually do. This is because I’ve only just touched the tip of the iceberg on these galactic crossing scenarios, doing case studies on two specific peoples’ claims, and explaining superficially why they are wrong while trying not to get into other aspects that I will cover on other posts (like the “pole shift”). In addition, these claims are just so incorrect – according to everything that we can observe – that it is somewhat difficult to figure out where exactly to start with the debunking.

If you feel that I have not explained myself clearly, would like more information, or care to argue the point, please leave a comment so I know what to address.



  1. I stumbled upon this blog, and can hardly believe that after a few short minutes, I have more useful information backed up by actual science, than I have been able to uncover in a year of looking for info on the whole 2012 hysteria. I’m a little embarrassed to admit I was leaning toward believing some of it, including the horizon project nonsense, although I questioned their credibility because of their obviously capitalistic view of the whole supposed crisis. Still, it was easy to get caught up in the idea. Largely because of the huge amount of info out there, it is really hard to wade through and analyze for the average person. Thank you.

  2. Thanks, Mike! I’m glad that you came here with an open mind and I was able to persuade you with the actual science, as opposed to others persuading you with legends of woe.

  3. Good points. Keep up the critique of the 2012 nonsense. However, there are people that are far more “out there” than Jenkins. These “prophets of nonsense” as I call them are making quite a lot of money on there claims. I believe we will see more of them as we approach 2012.

  7. Right on! It’s good finding others who use their heads when it comes to this stuff. It’s not a demon-haunted world, after all, and it’s because of people who wish to invest their time in spreading truth. Whew. Anywho, my blogspot has quite a bit on the Mayan Calendar “end” date and how it’s ethnographically/archaeologically *off* anyhow! Check it out!

    (I even found a video of Jenkins refuting astronomical speculations that even he attested to not so long ago)

  8. Ironically enough I was thinking about how much money could be made off people’s histeria on this stuff right before reading this.

    Nice job with all this info. Thank you for posting it.

  11. Question…? Regardless of whether it is a field of energy that is only within itself or if it is the center of a gravitation force which attracts what is above or below it, it is still a magnetic (or gravitational, which ever you prefer) pull of some sort. If there is a close alignment, with two magnetic forces wouldn’t there be some sort of magnetic reaction. If either one of our poles (North/South represented as Positive+/Negative-) line up with another magnetic force (depending on whether it is +/-) wouldn’t there would be a either a force of bringing the objects together or apart. Which would result in some sort of rotation, right? It would be massive forces but we are referring to our galaxy.

  13. This explanation is well put together. Because the people who expound the “2012 cataclysm theory” incorporate some astronomical science, it can be hard to tell what’s the real science, and part of the allure is that their explanations of the clockwork make sense to people who don’t know that much about astronomy. But yours is a very accessible explanation.. What isn’t clear to me is the reason for the solar system’s “peak and valley” orbit with relationship to the plane, it’s actual path, and the physics involved. Some diagrams I’ve seen have it as a kind of “slinky around a hula hoop” path, where we are not bobbing up and down like sine wave, but following a sideways spiraling path around the galaxy, so we are not only going up and down, but also inwards and outwards with respect to the center of the galaxy. Also, is the speed along that path always the same? In the “rolling down/up into the valley”, there is a slowing at the top and and a speeding up just before the bottom.

    • Correct, our path is not a perfect “flat” circle around the center of the galaxy. It does move up and down and back and forth a little bit, but ALL the stars in the galaxy do this. It would actually be VERY hard to get something on completely circular orbit with no ellipticity with no up-down motion. Saturn’s rings are an extreme example of this where, even there, particles move up and down an average of about 10 meters or so as they orbit around Saturn. And yes, Kepler’s Second Law applies where we will move faster and spend the least amount of time when closest to the center of mass (so we spend more time farther away from the galactic core and more time above/below the plane).

  14. our solar system is moving..then we might be moving into what they call the oort cloud? as we are on the edge of the milky way?? and we .sway…maybe like a space ocean…now,,as far as another planet nasa does hint around to an existence of another large body..i do not feel as if this object will hit earth…no..it would shake the cores of religions across the globe…because the true meanings were lost or twisted for the benefit of those who wish control…i love common sense…..huge applications of chemicals to the atmosphere..this would be to protect us from the influx of galactic energies…then why apply chemicals in early hours and at sun set..the energy from the sun is at its minimal .and if it is for galactic energies…would that not just enter …or is the sun a transformer of sorts?..what would account for the oddities that i am observing…for example..clear sky..no moon ..later moon still clear..no stars…no moon visible night…then visible all day…if not obscured by the chemical applications…large body hanging low in night sky with the appearance of moving yet nothing else in sky has that appearance….

  16. Someday we will have all the answers. I know that what we thought was impossible, changes with what ever the rulers think we can handle. Just try, you Scientist, to develop something that goes against the political grain and see how far you get. As long as you are in line with the community, truth or not, your explanations are acceptable. History tells us what happens to those who are trying anything that upsets the norm, gets squashed. Just try to say you can heal cancer, and if you are right, and you can, see what happens. What happened to the guys who drive their Ford truck on Nitrogen 10 years ago. Yet Japan just introduced a car that runs on it. So did BMW. We are not the owners of the truth so go ahead earn your paycheck. By the way who is paying for all this work anyway. It’s not your fault nor ours.
