Snapshot 1: An orbit with no inclination lies in the ecliptic plane.
Snapshot 2: An orbit with eccentricity between zero and one is an ellipse.
Snapshot 3: An orbit with a nonzero inclination is tilted with respect to the ecliptic plane.
Snapshot 4: The argument of the perihelion (
) defines the angle between the ascending node and the perihelion.
Snapshot 5: The longitude of the ascending node (
) is the angle formed at the Sun from the reference point (Vernal Equinox) to the body's ascending node (point where the body crosses the ecliptic, heading above the ecliptic).
