cartesianToSphericalfunction

Convert Cartesian to spherical. Zero vectors throw; longitude at either pole is conventionally zero.

Import it

import { cartesianToSpherical } from "@johnmorrisdotca/wakusei-planets/coordinates";

Definition

function cartesianToSpherical(value: CartesianAu): SphericalAu

Parameters

NameTypeDescription
valueCartesianAu

Coordinates with explicit origin, frame, epoch and geometric corrections.

Returns

SphericalAu

Spherical angles in degrees and radius in AU with the same context.

Examples

import { cartesianToSpherical } from "@johnmorrisdotca/wakusei-planets/coordinates";
console.log(cartesianToSpherical({ origin: "heliocentric", frame: "eclipticJ2000", epoch: "J2000", corrections: "geometric", xAu: 0, yAu: 1, zAu: 0 }));
{
  origin: 'heliocentric',
  frame: 'eclipticJ2000',
  epoch: 'J2000',
  corrections: 'geometric',
  longitude: 90,
  latitude: 0,
