Physics busy work, I haven't seen that in years.
a. find orbit distance r, center to center.
b. subtract re, and rm
a. forcegravity=centripetal force
GMeMm/r^2=Mm*w^2 r
but w=2PIr/period
manipulate that around until you get r as a function of period. change period to seconds.
insert G, Me and you have r.
b. subtract re+rm
