    Answer:

    G M m / R^2 = m v^2 / R     gravitational force = centripetal force

    G M = v^2 R   =    constant

    As v increases R will must decrease

    Take the moon as an example

    S = 2 pi R   where R is about 240,000 miles for one orbit

    S / 1 day = 54,000 miles/day  for a 28 day circuit

    S / 1 hr = 54000 / 24 = 2200 mph  which is much less than a satellite in orbit
