    Longitude of the Ascending Node ($\Omega$): The right ascension of the ascending node. This is the angle in the reference plane, measured eastward from the vernal equinox (or the $X$-axis of the reference frame), to the point where the orbit crosses the reference plane moving from south to north (the ascending node).
    Argument of Periapsis ($\omega$ or $\varpi$): The angle measured withi…
