    Most of the known moons of the planets revolve about their axes in the same direction as the planets themselves.
     Long-period comets do not appear to have orbits that are all in the ecliptic plane.
     The direction in which all planets orbit the Sun is identical to that of the Suns own rotation about its axis..
     The orbits of all the planets lie nearly in the same plane.
     The Moon orbits so that it keeps the same face toward Earth at all times.
