I did the math once for a 1 meter sphere of ice, entering at a fairly
shallow angle and at the lower end of the possible speeds. Assuming it could
hold itself together structurally (which is a big if), you should have
something like a 20cm sphere still frozen at the end of ablation.

Any numbers on how big the block would have to be? How small the
surviving
piece could be? I'm thinking of some of those chunks of ice that fall
from the
sky some times. Most come from planes. Could some be cometary?
