Orbital Chemical Heritage Theory: A Theoretical Framework Linking Elemental Composition and Planetary Proximity

This paper proposes the Orbital Chemical Heritage Theory, a new interpretive framework linking the elemental composition of spatially neighboring celestial bodies to their orbital evolution and stability. The theory is built on two main concepts: (1) chemical similarity between adjacent planetary bodies may originate from a common primordial nebula or prior material exchanges; and (2) gradual planetary mass loss, while small, could have a measurable cumulative impact on satellite orbits over geological timescales. A simplified Newtonian model is used to estimate how Earth’s ongoing hydrogen loss could affect the Moon’s orbit. The analysis shows a minor yet non-zero orbital drift over a million years. While the effect is negligible compared to tidal forces, it offers a complementary perspective that connects chemistry and orbital dynamics. This framework encourages interdisciplinary research across astrochemistry, planetary science, and celestial mechanics
