By comparison, this famous crater was caused by an object 1/400,000th as massive.

Hey /sci/.

Was at class today and the professor was discussing impact events (rather unrelated to my course, but I found it interesting nonetheless). A student asked if if a 10km rock hit the planet would it leave a 10km crater (Hard to imagine how these idiots got into Uni) which, whilst obviously wrong, made me wonder if there was any equation or general rule as to the size of a crater.

Obviously speed and angle of impact will greatly affect crater size but generally, is there a rule?

Sorry about the lack of coherence in my writing, it has been a long day.

tl;dr what's the rule of thumb for size of impact body and crater size
