James wondered for a moment. "Well, if my high school physics class meant anything, it really depends on the magnitude of it's pull." He said in reply to Annett. " If I remember correctly, when you are in orbit you are really falling, but the rotation of the planet keeps you from falling straight down. That is, if you don't force anything. So, I think if we find out the rate of Ceres pull, we could probably handle being thrown back on course."
