I'll take a look later and comment back. > > How big is the anomalous acceleration at our solar system? If you're talking about the "anomalous" acceleration of the solar system around the milky way, you can calculate it using the centripetal acceleration formula. I've calculated it in the past. If the Sun is rotating around the galaxy at 220 km/s, and the distance to the center of the Milky Way is ~ 26000 light years, and assuming we're orbiting the galaxy in a circle(which sounds like a good approximation) the Sun must be subjected to a centripetal acceleration ac = v^2/r ~= 2 x 10^-10 m/s^2 You might be interested in a thread in physics forums called "solar system motions" (http://www.physicsforums.com/showthread.php?t=383916) where I discuss the subject with some members. The thread called "Alternative theories being tested by Gravity probe B " (http://www.physicsforums.com/showthread.php?t=104694) from which the previous thread was split off, is interesting also.
