Somewhere between 44,000 LY to 65,000 LY
But, it could be as small as 35,000 LY.

The problem is we are not exactly sure of the size of our galaxy, only recently did science suspect that it was a sprial barred galaxy and so larger than previously thought.

According to Wikipedia: http://en.wikipedia.org/wiki/Milky_Way
"The fact that the Milky Way divides the night sky into two roughly equal hemispheres indicates that the Solar System lies close to the galactic plane."

"The galactic disk, which bulges outward at the galactic center, has a diameter of between 70,000 and 100,000 light-years.[17] The distance from the Sun to the galactic center is now estimated at 26,000 ± 1400 light-years, while older estimates could put the Sun as far as 35,000 light-years from the central bulge."

"The Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Galaxy's Orion Arm, in the Local Fluff, at a hypothesized distance of 7.62±0.32 kpc from the Galactic Center.[24][25][26][2] The distance between the local arm and the next arm out, the Perseus Arm, is about 6,500 light-years."

According to Wikipedia: http://en.wikipedia.org/wiki/Barred_spiral_galaxy
"A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure comprised of stars. Bars are found in approximately half of all spiral galaxies[1]. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well."

Due to the bar and the unknown size of the interior bulge I couldnt' find how far we are in the Z axis (up and down), but according to the article we are pretty close to the equatoral plane and the spiral bar is inclinded at 44 degrees between the earth and the galacitc center.

On December 12, 2012 our solar system will be precisely in line with the galactic equatorial plane.

This website has a lot of information about where we are relative to the galactic plane, where we're going, etc.,. Lots of good graphics too..! ==>http://biocab.org/Coplanarity_Solar_System_and_Galaxy.html

Well, only the oldest stars, the population 2 stars, are in orbits that take them far away from the galactic plane. Barnard's star for instance, is close to us now, only 5 light years away, but its orbit will eventually take it into the galactic halo. But the Sun is population 1, so it stays in the galactic plane to within a hundred light years or so. That's about the thickness of the Milky Way where we are. An interesting question.

This is only slightly better than the other questions which you have asked... "Is the Earth hollow?" "Where is Nibiru now?"

If you have gone onto false 2012 sites again, you have been once again misinformed. Sometimes, when things speak of changes in the sky, they only speak in terms of AS VIEWED FROM EARTH. Not the actual moving of objects. When it is spoken that the Sun will rise in the Galactic center on 2012, this is meant to be AS VIEWED FROM EARTH. The Sun is not actually moving towards the galactic center. It is a visual phenomena as viewed from Earth caused by precession.

The Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Galaxy's Orion Arm, in the Local Fluff, at a hypothesized distance of 7.62±0.32 kpc from the Galactic Center. The Milky Way is a barred spiral galaxy. The Galaxy's bar is thought to be about 27,000 light-years long, running through its center at a 44 ± 10 degree angle to the line between the Sun and the center of the Galaxy. This will remain as such and will not suddenly change to zero simply because a 2012 website may have claimed so.

The Apex of the Sun's Way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The Sun's orbit around the Galaxy is expected to be roughly elliptical with the addition of perturbations due to the galactic spiral arms and non-uniform mass distributions. In addition the Sun oscillates up and down relative to the galactic plane approximately 2.7 times per orbit.

It takes the Solar System about 225–250 million years to complete one orbit around the galaxy. As precession is measured as a 26,000 year cycle, it is in no way related to an 80 million year up and down oscillation cycle. And most certainly is not related to 2012.

As there exist an immense amount of 2012 websites proclaiming false information, it would be wise to avoid such and stick to real science sites or you will continue to be misled by disinformation.
