You can put the planets and satellites anywhere you want: no law
dictates their periods of revolution or rotation.  The only law
you must observe is the harmonic law: p^2/r^3 must be constant,
where p is the period of revolution and r is the radius of the
orbit.

The constant is (4*pi^2)/(M*G) where M is the mass of the
primary body (the sun for a planet, the planet for a satellite)
and G is the gravitational constant,
approximately 6.67259*10^-11 m^3/kg sec^2.  This version of the
law does not hold if the mass of the planet/satellite is not
negligible with respect to the mass of the sun/planet, which is most
unlikely.

So you can choose either period of revolution or distance, but not both.
Rotations can be anything you want.
