The Resonant Structure of xGEO and Implications for Cislunar Domain Awareness

Rawat, A.; Rosengren, A.; Ross, S. +1 more

A rigorous dynamical definition for xGEO is the critical distance at which the secular contributions from the lunisolar perturbations exceed those from Earth oblateness, known in astronomical parlance as the Laplace radius. xGEO fundamentally represents a restricted four-body problem (R4BP), which can be approached locally using the perturbed-Hami…
