Struct vsop87::KeplerianElements

pub struct KeplerianElements { /* private fields */ }

Structure representing the keplerian elements of an orbit.

Implementations

impl KeplerianElements

pub 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 parabolic orbit. Negative values cannot exist.

pub 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.

pub 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.

pub 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.

pub 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.

pub 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.

Trait Implementations

impl Clone for KeplerianElements

fn clone(&self) -> KeplerianElements

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeplerianElements

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<KeplerianElements> for VSOP87Elements

fn from(elts: KeplerianElements) -> Self

Converts to this type from the input type.

impl From<VSOP87Elements> for KeplerianElements

fn from(elts: VSOP87Elements) -> Self

impl PartialEq for KeplerianElements

fn eq(&self, other: &KeplerianElements) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
