Raytraced image showing the argument of the periapsis for a "minor" object in an elliptic orbit around a larger object.

Letters in the image denote:

• A – Minor, orbiting body
• B – Major body being orbited by A
• C – Reference plane (e.g. the en:ecliptic)
• D – Orbital plane of A
• i – Inclination

The green line is the node line; going through the ascending and descending node; this is where the reference plane (C) intersects the orbital plane (D).

This image was created using the Persistence of Vision Raytracer and the scene description code found on the page image:Angular Parameters of Elliptical Orbit.png, using View=3 as described on that page.

Raytracet billede der demonstrerer periapsisargumentet for et mindre himmellegeme i elliptisk kredsløb om et større.

Bogstaverne i billedet angiver:

• A – Det mindre himmellegeme
• B – Det større himmellegeme
• C – Referenceplan, f.eks.
• D – Baneplan for A's omløb
• i – Banehældning, eller inklination

Billedet er lavet med raytracin-programmet Persistence of Vision Raytracer, samt den scenarie-beskrivelse der er vist på siden Image:Angular Parameters of Elliptical Orbit.png under brug af View=3 som beskrevet på den side
