A meteor hit on the polar ice cap won't have much effect on the rotation rate, although it could vaporize some of the ice cap and cause a world-wide deluge. A hit near the equator big enough to slow the rotation rate by a factor of 8 or 10 would be a catastrophic, world-changing event. It would contain enough kinetic energy to vaporise much of the ...

This is an interesting question and one that probably needs detailed simulation to settle. But one can make the following broad prediction: the shape of the meteorite would have minimal effect on the outcome, for the following reasons: At the kinds energies let slip in the moments of impact and the kinds of pressures and temperatures that prevail, all ...
