Graphing the Ecliptic

  1. I need to graph the Ecliptic at a Radius, R, around the earth.

    It intersects the equator axis at the equinoxes.

    The Angle from the equinoxes line to the maximum Z displacement is the angle of the Obliquity.

    Could someone give me some ideas on how to graph the thing

    and how to exactly how to calculate the Longitude of the Ascending Node for each of the

    Equinoxes.
