Where is Earth in this Galaxy?

Our solar system is at what radius from the center of the Milky Way galaxy?

I just have to say it... Third Rock from the Sun? <.<

Apparently our sun is 26,000 light years away from the centre of the galaxy.

Why is this in PPR?

.

I just think it would wind up here anyway, as soon as someone makes a comment about geocentrism, another person reports it to the moderators, then it gets moved here anyway.

geocentrism is for the mentally ret*d.

In the Orion spiral arm, about 26,000 LY from the galactic center.

What do I win?

A free ticket to attend geocentrism lectures.

Since someone brought up geocentrism it should be pointed out that one can pick any point as the center of either the universe or the Solar system. I could pick the tip of a carrot I have in my refrigerator and there's nothing wrong in that. The problem is, of course, that all the movements of the planetary bodies and the stars in the galaxy and the galaxies themselves become hellishly complicated whereas a Solar centric Solar system is rather neatly simple for planetary movements and the center of the galaxy (does our galaxy have its own name?) serves nicely for understanding the movements of the stars contained. As far as I know there is no choice made for all the galaxies except they all seem to be receding from whatever point you pick.

Its to be estimated being between 25.000 to 30.000 ly on the Sagittarius-Carina Arm.
New information on the structure of the Milky way suggest that the Sagittarius and
Norma arms not being arms, but only concentrations of gas, with some young stars.

Pretty cool Spudnik.

A free trip to Wikipedia.

Why? Have you gone through the relevant calculations and made the measurements so that you can say with confidence that you know geocentrism is wrong? For all that you can actually say or prove, there is no reason to favor either heliocentrism or geocentrism.

While the earth causes perturbations in the sun's motion, the earth is only
three millionth the mass of the sun so it can easily be said to orbit the sun.

cool

its "obscured" because it will take us intill mountains can knit sweatters untill we pass around the other side?

Meh. I haven't done the calculations to estimate the mass of either the sun or the Earth, or made any measurements about the effect of each's gravity on the other, so I can so no more than that scientists have studied it and come to the conclusion of heliocentrism over geocentrism. I take them at their word, since I can't be bothered to reproduce the work on my own.

Although, if we say that motion is relative and all inertial reference frames are equally valid (as we maintain in Newtonian mechanics) then we could quite easily say that the Sun orbits a stationary Earth. All the other planets would be seen as orbiting the Sun, but the Sun goes around the Earth.

:S

centrism, center.

geocentrism, earth in center. even if playing with perspectives, for geocentrism to work, the sun AND the solar system moves in an awkward orbit around the earth, along with the entire universe, which at this point, because of relativity, would basically be standing still.
all logic just went for a walk

its not possible to make a realistic geocentric reality to work.
