[Why would the sun orbit the Earth when the sun's gravity is so much stronger?]
The amount or strength of the "gravity" of the sun is assumed and guessed at and is not known. IF it had huge “gravity” and we had a stationary Earth locked into place it would still go around the Earth because the Earth would not give in to the sun but in fact the sun would hold its orbit because of it.

Attention, Fundies. Get over it. The Earth is NOT the center of the universe. We live on an insignificant little planet in a solar system around one star on the outer fringes of the Milky Way Galaxy. Our sun is one star out of 200 billion in this galaxy. There are over 200 billion galaxies. Grow up, accept it, and admit that your fucking Book of Fables, i.e. the Bible, is wrong.

Yes, I suppose that's true. Now, I'm not sure how you would "lock" the Earth in place, particularly without the tidal forces involved ripping it to shreds, but let's ignore that for a moment.
Let's see... the sun masses 1.9891×10^30 kg, and the mean distance to the earth is 149.6×10^6 km. The sun "orbits the Earth" once per year, giving it a period of approximately 3.1536x10^7 seconds...
2*pi*149.6e9 m = 9.4e11 m
9.4e11/3.15e7 = 29,806 m/s
29806^2/149e9 = .006
F=ma, so
F= .006*1.9891×10^30
F= 1.19346e28 N
So the Earth (massing 5.9742×10^24 kg) should be experiencing 1.19e28 N of force... or nearly 2000 m/s^2 of acceleration.
So, why exactly aren't we being crushed against an invisible vise with 200 times the force of gravity (at the surface of the Earth)?
Wolf O'Donnell -- Please don't blame this idiot on the U.S. education system. The system has it's problems, but nobody could educate a mind like his.
Originally, yes, the sun's mass was deduced from planetary orbits and is therefore based on an assumed heliocentric system.

If my aunt had balls, she'd be my uncle. What's your point?
oh shit.... oh shit.... oh shit.....
To quote Douglas Adams: Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.
MK, when you're right, you're right. Between the antiscientific ravings of Carico, dad, and childol (and, I think, one other featured poster this month), those of JohnR7 hardly even stand out anymore.
Wow, that No Child Left Behind thing was a big FAIL wasn't it?
Edit: @ Anonymous/David D.G.: don't forget afdave. :)
"So, is childol the product of a US science education? If so, I can't for the life of me understand how you Americans have so many leads in the field of science..."
Well, first we weed out the real morons.. like the fellow being quoted here. Then we have the brightest folks from all over the world come and help us out. Think of American won Nobel prizes as World won nobel prizes. I'm proud that Americans are part of it, but grateful to scientists the world over who are also part of it.
Science is at its best as an international force. International projects like the LHC our are best way forward in discovering the secrets of the universe.
Meanwhile childol can be left to examine the lint that was created as a result of the gravitational pull of his belly button.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
