    	No.  If the Moon had the same mass as the Earth that would be
    the case (but then the Moon wouldn't be at the distance it is).  As it
    is only 1/81 as massive, the orbit would be a lot closer.  I work out
    the selenosynchronous (?) orbit to be about 93000 km from the Moon's
    center.
