API Reference / earthHeliocentric · function
Function: earthHeliocentric()
function earthHeliocentric(data, jde): [number, number, number];
Heliocentric Earth of date, preferring data.earthPack over VSOP87D.
The Python side can intercept inside Vsop.heliocentric because it dispatches on a body name; here vsopHeliocentric takes a series, so Earth's six call sites go through this helper instead. Same contract as vsopHeliocentric: ecliptic coordinates OF DATE. Inert until a pack is loaded.
