Summing the Planets: How Eight Constants Reconstruct the Solar System from Mercury to Pluto

This paper presents the discovery of an underlying additive structure in the orbital periods of the Solar System’s classical planets. Beginning with Mercury, each planet’s orbit can be generated by cumulatively adding a fixed set of orbital deltas—revealing that planetary spacing follows a quantized, stepwise arithmetic progression. This additive sequence reconstructs the entire Solar System out to Pluto using only simple subtraction and summation applied to published NASA orbital period data. The findings challenge prevailing models that attribute planetary distribution solely to chaotic or resonance-based dynamics. Instead, they suggest a deterministic scaffold where each orbit encodes information about those before it. This mathematical structure—reproducible from raw data—may point to a deeper principle in planetary system formation and offers a testable framework for comparative analysis with exoplanetary systems
