   The Classical Keplerian Elements
   The six classical elements, often referred to as the Keplerian Elements, are derived by analyzing the geometry of the orbit in relation to a defined reference plane, typically the fundamental plane of the celestial sphere or the orbital plane itself. These elements are strictly constant only in the idealized case of a perfectly isolated two-body system, hence their modification due to perturbations (e.g., [atmo…
