fn heliocentric_position_ecliptic(body: &str, epoch: &[Epoch<Tdb>](../../structs/epoch/)) -> [Option<nalgebra::Vector3<f64>>](https://doc.rust-lang.org/std/option/enum.Option.html)
Compute heliocentric position of a planet in the ecliptic frame [km].
Returns None if the body is not a recognized planet.
Accuracy: ~1 arcminute for inner planets, sufficient for sun-direction lighting.
Time scale
Section titled “Time scale”Meeus ephemerides take a dynamical time argument (TDB), so this signature
requires &Epoch<Tdb> — the caller converts at the boundary
(utc.to_tdb()).
