I remember reading an article not too long ago that provided much info on
this, as well as a formula that might predict various outcomes, depending on
which body in our solar system you were interested. I could not find it on
my HDD, so I did a search on google for 'impact central uplift formula'

http://www.google.com.au/search?hl=en&q=impact+central+uplift+formula&meta=

and found this, it provides the formula.

http://www.bookrags.com/sciences/earthscience/impact-crater-woes-01.html

There is a fair amout of other good reading provided by the search.
All the best, Kevin.
