It is substantiated that the Solar System corresponds not to a static Newtonian gravitational field, but to a dynamic gravitational field that is also formed by planetary motion and therefore adapts to changes in the positions of the planets within it. It is because of this that gravitational pseudo-forces, just like centrifugal pseudo-forces of inertia, are orthogonal to the superharmonic quasi-circular orbits of the planets at every point. The correspondence of the superharmonic trajectories of the planets' motion exclusively to the laws of conservation of angular momentum and energies (the Newtonian of inert free rest energy and the Keplerian of ordinary rest energy of matter) is proven. The inconsistency of two-focus elliptical orbits with the law of conservation of angular momentum is substantiated. Equations for superharmonic single-focus quasi-circular (asymmetric oval) planetary orbits have been derived, consistent with both the laws of conservation and astronomical observations. Modernized and substantially improved versions of Kepler's laws have been formulated.
