Struct vsop87::KeplerianElements

pub struct KeplerianElements { /* fields omitted */ }

Structure representing the keplerian elements of an orbit.

Methods

impl KeplerianElements

fn eccentricity(&self) -> f64

Gets the eccentricity of the orbit (e).

A number smaller to one would be a closed ellipse, while 0 would be a circle orbit. Values higher than one would be hyperbolic orbits, that are not closed, while a 1 would be a parabolical orbit. Negative values cannot exist.

fn semimajor_axis(&self) -> f64

Gets the semimajor axis of an orbit (a), in AU (Astronomical units).

This value represents the average distance from the orbiting body to the center of mass.

fn inclination(&self) -> f64

Gets the inclination of the orbit (i), in radians.

This value represents the inclination of the plane where the object is orbiting with respect to the reference plane.

fn ascending_node(&self) -> f64

Gets the longitude of the ascending node of the orbit (Ω), in radians.

This value represents the angle in the orbit ellipse of the point where the reference plane and the orbit plane cross when the orbiting body crosses the plane ascending in the orbit.

fn periapsis(&self) -> f64

Gets the longitude of the periapsis of the orbit (ϖ), in radians.

This value represents the angle in the orbit ellipse of the nearest point of the orbit to the center of mass of the system.

fn mean_anomaly(&self) -> f64

Gets the mean anomaly of the orbiting object at the given epoch.

This value represents the angle in the orbit ellipse of the orbiting body at the given moment.
