The large-scale structure of the Solar System is conventionally explained by gravitational orbital dynamics, whereas the interplanetary magnetic environment is explained by solar-origin plasma and magnetic-field processes. This study proposes the hypothesis that these two levels of organization may not be entirely independent and that frequency-selective electromagnetic coupling between the Sun and planets may contribute to central-motion organization.

The model predicts that not all common frequencies have the same physical significance. Instead, the highest significant frequency components within the relevant measurement band of interacting Sun-centered and planet-centered electromagnetic-plasma systems should preferentially approach or overlap.

Published Wind–ARTEMIS observations reported common low-frequency spectral peaks between upstream solar-wind/interplanetary magnetic-field measurements and magnetotail measurements near lunar-orbit distance, particularly at approximately 0.64–0.69 mHz and 0.89–0.93 mHz. In contrast, significant ARTEMIS peaks at approximately 0.37–0.47 mHz lacked corresponding Wind or ACE peaks.

These observations are reinterpreted as a test case for frequency-selective coupling. The proposed mechanism is not considered demonstrated; rather, the study develops falsifiable predictions involving cross-spectral coherence, phase relationships, spectral ordering, repeated lunar magnetotail passages, control intervals, and comparative observations at other planets.
