Function astro::orbit::elliptic::rad_vec_frm_true_anom

pub fn rad_vec_frm_true_anom(true_anom: f64, a: f64, ecc: f64) -> f64

Computes the radius vector of a body in an elliptic orbit from it's true anomaly

Returns

• rad_vec: Radius vector of the body | in AU

Arguments

• true_anom: True anomaly of the body | in radians
• a : Semimajor axis of the orbit | in AU
• ecc : Eccentricity of the orbit
