Graph Style: Classical Orbit Elements

A plot of the angles and the semimajor axis of the classical osculating orbital elements, sometimes referred to as Keplerian elements, computed using ephemeris with respect to the object's J2000 coordinate system, as a function of time. Eccentricity is not plotted.

CurveTitleElementTypeDimensionDescription
1InclinationInclinationReal Number or TextAngleThe angle between the orbit plane and the XY plane of the coordinate system.
2RAANRAANReal Number or TextAngleThe angle in the XY plane from the X axis to the ascending node, measured in a right-handed sense about the Z axis. in the equatorial plane. For equatorial orbits, the ascending node is defined to be directed along the positive X axis, and thus the value is 0.0.
3Arg of PerigeeArg of PerigeeReal Number or TextAngleThe angle from the ascending node to the periapsis vector measured in the orbit plane in the direction of the object's motion. The periapsis vector locates the closest point of the orbit. For a circular orbit, the value is defined to be zero (i.e., periapsis at the ascending node).
4Mean AnomalyMean AnomalyReal Number or TextAngleA measure of the time past periapsis passing, expressed as an angle.

Y2 Axis: Distance

CurveTitleElementTypeDimensionDescription
1Semi-major AxisSemi-major AxisReal NumberDistanceA measure of the size of the orbit. Orbits with eccentricity <1 are ellipses, with major and minor axes identifying the symmetry axes of the ellipse, the major axis being the longer one. The value is half the length of the major axis.
