When a stellar object falls into the earth's surface, it creates a crater on the ground. Most of the times, when people refer to these things, they refer to their age and their diameter/radius. My question is mainly about the radius. Is there a dynamical way to solve for the shape and radius of a crater such an impact can cause? Eg if I said that a meteor of mass 0.001 the mass of the earth, and initial velocity of 200 km/s falls horizontally on the ground, would I be able to calculate the radius of the crater?
