(The Moon's orbital plane is flattened back toward the ecliptic, at just a 5.1° inclination.) This means the Moon drifts ...

The original eccentricities of the orbits of both planets and satellites would be considerably reduced; the inclination to the plane of the ecliptic would be small at the commencement, and would ...
