Properties

argumentOfPeriapsis: number

Argument of periapsis (ω), degrees.

eccentricity: number

Eccentricity, 0 (circle) ≤ e < 1.

inclination: number

Inclination to the parent's reference plane, degrees.

longitudeOfAscendingNode: number

Longitude of the ascending node (Ω), degrees.

meanAnomalyAtEpoch: number

Mean anomaly at the epoch (M₀), degrees.

period: number

Orbital period, seconds. 0 = derive it from the parent's gravitational parameter (GM).

semiMajorAxis: number

Semi-major axis, metres.
