Spin-Axis Organization and Orbital Spacing in Planetary Systems: A Phenomenological Framework for Radial-Wave Structure

The architecture of planetary systems exhibits structured patterns in both orbital spacing and spin-axis orientations, suggesting the presence of underlying organizing principles beyond purely stochastic formation processes. In particular, correlations between planetary obliquities and orbital spacing suggest the possibility of underlying organizing principles beyond purely stochastic processes such as impacts and migration. In this work, a phenomenological framework is proposed in which rotational dynamics of a central body generate radial wave–like spatial structure that organizes characteristic orbital distances. Within this framework, planetary bodies forming within these radial structures may inherit correlated spin-axis orientations and orbital spacing conditions. The resulting patterns are interpreted as manifestations of large-scale radial spatial organization rather than independent dynamical coincidences. The approach is descriptive and does not modify gravitational dynamics; instead, it provides a geometric framework for analyzing obliquity correlations and orbital spacing within planetary systems. Possible implications for planetary system architecture are discussed, while detailed dynamical modeling is left for future work.
