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

I'm pretty sure there's plenty of models to calculate that, but I doubt they are as simple as a single equation.

What kind of rock it impacts into also has to come in somewhere.

Wouldn't that mean all craters have a size of about 1?

1. Go to the nearest library or use google
2. Search for books on geology discussing impacts
3.???? WUTS GOIN ON HERE????

You would have to take into account things like the terrain it hits, the kind of material that hits, and obviously, its size and format; I suppose differential equations everywhere, which make me go like the pic

There isn't really a rule. You can calculate it sure, but there isn't any hard and fast rule given how vastly different any two impact events can be.
