Stresses in asteroid during close flyby
I think I understand the concept of tidal stress, although it is difficult for me to wrap my head around tidal stress in a relatively small body such as an asteroid, where the closest point to earth center and the farthest point may only differ by less than 100 yards. In other contexts, stress in a body is related to the time rate of change of acceleration, or "jerk". Thus jerk would be higher on an asteroid at say 17,000 miles from earth than at several hundred thousand miles. Or is this effect negligible? Or are we saying the same thing?
