Here's a question for those of you more familiar with impact structures on
Earth. I believe I saw somewhere that craters fall into 2 main categories?
simple and Complex with the later having a central uplift, concentric rings,
etc among other things.

My question is: How small can a complex crater be? Is there a definitive
size restraint or does it completely depend on a multitude of variables such
as the make-up of the impacting body, velocity, impact angle, target rock,
etc?

Any help is appreciated,
