It will be interesting that’s for sure.

Boom!

Curious what the formula is for atmospheric deterioration.

Here's a paper on the subject: METEOROID ABLATION MODELS.

I don't think there's any one formula because meteors are of widely varying compositions. Some are balls of rock, some are almost solid chunks of iron. Some have odd shapes with "protuberances," which break up into small pieces soon after contact with the atmosphere, and some are compact.

Also, the angle at which they enter the atmosphere plays a big role in how they behave.

thanks, and good points regarding the varying properties! I suppose velocity is a factor as well
