Function vsop87::vsop87d::uranus

pub fn uranus(jde: f64) -> SphericalCoordinates

Calculates VSOP87D solution for Uranus.

This function calculates the VSOP87D solution (heliocentric ecliptic spherical coordinates for the equinox of the day) for the planet Uranus. The parameter needed is the Julian Day (JD) for the given date. It returns the VSOP87D solution ina SphericalCoordinates struct. Those values are the spherical coordinates of the planet, with the Sun in the center and the ecliptic plane as reference latitude = 0.

Example

Given a date in JD, we can get the position of the planet Uranus in the solar system using spherical coordinates. In this case, we calculate where Uranus was in December 19th, 1199.

use vsop87::vsop87d;

let coordinates = vsop87d::uranus(2159345.0);

assert!(coordinates.longitude() > 1.9333853934 && coordinates.longitude() < 1.9333853936);
assert!(coordinates.latitude() > 0.0088045917 && coordinates.latitude() < 0.0088045919);
assert!(coordinates.distance() > 18.58414975 && coordinates.distance() < 18.58415051);
