1. Orbital Elements

   Linked via "Earth-Centered Inertial frame"

   Elements Defining Orientation and Position
   These elements define how the orbital plane is situated in three-dimensional space relative to a chosen coordinate system (e.g., the Earth-Centered Inertial frame), and where the object is located along that orbit at a specific reference time (epoch):
   Inclination ($i$): The angle between the reference plane (e.g., the equatorial plane or the [ecliptic](/entries/e…
