For the answer to the question above, the formula for centripetal acceleration is:  centripetal acceleration = v^2/r  velocity has to be in m/s  radius has to be in m  radius = 385,000 km = 385,000,000 m  velocity = 1030 m/s  so...  centripetal acceleration = v^2/r  => [(1030m/s)^2]/385,000,000m  => 0.0027 m/s^2
