Crate rhorizons

Access NASA JPL Horizons system from Rust. This crate is written in asynchronous code, therefore you probably want to use it in conjunction with tokio.

Example

#[tokio::main]
async fn main() {
    println!("Major bodies in the Solar System.");

    for body in rhorizons::major_bodies().await {
        println!("{} ({})", body.name, body.id);
    }
}

You can check more examples in the source repository.

Structs

EphemerisOrbitalElementsItem

Orbital Elements of a body. Units are km, s and degrees

EphemerisVectorItem

Position (in km) and velocity (in km/s) of a body.

MajorBody

Planet, natural satellite, spacecraft, Sun, barycenter, or other objects having pre-computed trajectories.

Functions

ephemeris_orbital_elements

Get orbital element ephemeris (e.g. eccentricity, semi-major axis, …) of a major body relative to the Sun’s center

ephemeris_vector

Get vector ephemeris (position and velocity) of a major body. Coordinates are relative to the Sun’s center.

major_bodies

Get names and identifiers of all major bodies in the Solar System.
