Abstract

The mystery of why planets are spaced in a mathematical pattern around the Sun has baffled scientists since astronomer Johann Kepler (discoverer of the first three laws of planetary motion) made the initial futile attempt in J595 to find the solution. This elusive solution to a definitive Fourth Law of Planetary Motion explaining the spacing of planets is proposed. The four laws are powerful evidence that planets began as Sun-like masses of nuclear energies that evolve via the processes of internal nucleosynthesis through five common and observable stages of evolution. The Fourth Law is the final link in a FLINE paradigm of planetary origins comprised of three chronological. inseparable and ongoing realities: The Four Laws of Planetary Motion (FL). Internal Nucleosynthesis (IN) and Evolution (E). The pace of evolution through each of the five stages and the planetary features in each stage are revealed as functions of planetary mass and distance from the Sun. All planetary systems embrace these FLINE principles, of which more remain to be discovered. Every planetary anomaly should be examined closely in this new perspective.
