Every morning observers stationed on the Earth observe the Sun rise in the morning, move along arc of circle, and set in the evening. Apparantly the Sun is rotaing around the Earth at distance 1a.u. and period ~24 hours. The centripetal accleration of the Sun must be enormous. What is the force that causes the above described centripetal acceleration?

Alexander always asks thought provoking questions (but I think he usually knows the answer in advance. :-))
Alexander brings up a good point. A rotating reference frame can be treated just like a non-rotating frame, with all of Newton's laws applying, provided that you postulate two additional "forces" in your frame: (a) the centrifugal force, which tends to push things away from a central axis; and (b) the coriolis force, which tends to push moving things at right angles to the direction of their motion.
Given those extra two forces, I would have to say that the sun is kept in its "circular path" by means of the coriolis force, which pushes it radially inward toward the earth in response to its tangential motion.

The Earth rotates on its axis. It revolves around the Sun. Gravity pulls it towards the Sun, while inertia keeps it going forward. Result is its orbit.

the gravitational force that keeping the earth rotate around the sun. the the centripetal acceleration of the earth is to keep the earth on orbit with sun.

Fc = mr(omega)^2 = (mass of sun)*1A.U.*(2pi/24hrs)^2 The suggested force would only be
1.57353118 × 10^33 N

Okay. I'll bite. This has to be bait. Otherwise it's a really STUPID question. The EARTH rotates around the SUN.....

The Earth moves around the sun, not the other way around >_<

Very funny.
Now I am wondering just how many people will read this and believe it.
