Don't know if there's a way to do "hyper-velocity impacts in a nutshell?" Just boil it down?

I know, I know, there's probably a lot of theory behind it. I'm just thinking "General Info..."

Obviously if it's moving that fast it'll highly compress the atmosphere in front of it, probably turning it into a high-temperature plasma. That, in turn, might well scorch or melt the surface of the impactor. How am I doing? But in addition to this, the plasma is highly conductive and prone to magnetic field influence. And the Earth has a doozy. So, thre's probably some influence from that. Not to mention layers of charge in the atmosphere. A rotating magnetic body can create electricity, no? So, can we assume the Earth does the same with its magnetic field and rotation? Or is the field somehow stationary despite the earth's rater apparent rotation?

Anywho, if soeone has a hyper-velocity impact-in-a-nutshell resource, I'd appreciate a lik or reference. Sounds interesting. Would love to absorb it. :)
