Rule of Thumb for hypervelocity impacts

The size of the crater is ~20 times the size of the impactor.

Ceres is ~500 km in radius (actually 466, but wait...), so the crater on Earth would be ~10,000 km in radius.

Earth is only 6371 km in mean radius.

This would not be a nice day. So please don't drop it...

        It works better for smaller impactors. - et - 11/6/2006 7:19:44 PM
