I think I am lost in your math. Miles is a distance measurement and MPH is a velocity measurement. I’m not sure how you get from 17K mph to 1.08r.

Sorry if I missed something.

I don't know how to do this on the computer.... Velocity sub orbit equals the square root of the radius times the surface gravity sub orbit.

If I'm wrong, 'splain me. Won't be the first time I've been beat for math issues.
