Edit to add: read the article, it sounds exactly like it's the Roche limit, applied to passing objects instead of orbiting objects.

What happens can be simulated, and someone did that back in 1998.[1] There are pictures of the simulation result. Objects moving fast enough don't get disrupted. "Our results indicate that this limit is well below the mean encounter speeds of long-period comets with Earth. Thus, we predict that few comets ever undergo strong tidal disruption in the terrestrial planet region." Since 1998 many more near-earth objects have been found, because more automated equipment is looking for incoming threats. Don't know about speeds. Looking back at the 1998 simulations using new data might be useful.
