    The differance in MM is 0.01085978
    This means that after 1 / 0.01085978 = 92.08 orbits Alexis catches up again
    with its rocket.
    For 92 orbits it uses 92.08 / 14.31 = 6.43 days
    So they will catch up on eachother every 6.43 days; presuming the MM's don't
    change. But they
    do due to friction of the upper atmosphere.
