Function astro::planet::geocent_apprnt_ecl_coords

pub fn geocent_apprnt_ecl_coords(planet: &Planet, JD: f64) -> (EclPoint, f64)

Computes a planet's geocentric, apparent ecliptic position, corrected for light-time

Returns

(ecl_long, ecl_lat, rad_vec)

• planet_ecl_point: Ecliptic point of the planet | in radians
• rad_vec : Geocentric radius vector of the planet | in AU

The coordinates returned here refer to the apparent position (from Earth) of the planet at the time of interest by correcting the true coordinates for the effect of light-time.

Arguments

• planet: Any variant of Planet
• JD : Julian (Ephemeris) day
