Namespace:  AGI.Foundation.Coordinates
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 20.2.404.0 (20.2.404.0)
public double Eccentricity { get; }

Property Value

Type: Double

Eccentricity e can be calculated on the basis of semimajor axis a and semiminor axis b as follows:

e = sqrt(1 - (b / a)^2)

Referring to the following diagram, e can also be expressed as a / f, where f is the distance from the center of the ellipse to the center of mass of the central body:
