Newton's gravity equation

F=G (Mm) / r^2

At 10,000 miles you can use the 600lbs to find the value of

G (Mm) in the appropriate units:

GMm = (10e3) ^2*600=6e10

So divide this by your other distances squared (in miles). That will be the value of force in pounds. (I don't see your other distances on my app)
