Description
The mass-radius relationship of exoplanets provides a fundamental connection between their observable characteristics and internal structure. In this study, we develop a comprehensive framework in order to derive key planetary parameters, including surface gravity, mean density, escape velocity, moment of inertia, spin period and atmospheric scale height, directly from mass and radius measurements. We adopted a generalized power-law mass-radius relation R∝M^α to incorporate the effects of composition (rocky, icy, gaseous) and structural constants, allowing estimation of dynamical and thermal properties for diverse exoplanet types. Scaling laws for rotational and break-up periods, as well as gravitational binding energy, are presented, providing insight into stability and evolution of exoplanets. This framework offers a practical toolkit for interpreting observational data, enabling constraints on planetary composition, spin states, and atmospheric retention. The results can be applied to characterize exoplanets, whether they are discovered via transit, radial velocity or direct imaging surveys- bridging the gap between observational metrics and intrinsic planetary physics.
