Siderust

Why it exists

Siderust collects the pieces you need for ephemerides, observers, coordinates, and event searches. We keep the library close to the underlying models and validate the results against established references.

Key Features

• VSOP87 & ELP2000 planetary/lunar ephemerides
• Type-safe coordinate systems (ICRS, Ecliptic, Topocentric)
• No unsafe blocks, no hidden allocations
• Validated against authoritative data

Getting Started

# Add to your Cargo.toml
[dependencies]
siderust = "0.9.1"

# Compute Mars position
use siderust::{
    bodies::Mars,
    astro::JulianDate,
};
use chrono::Utc;

let jd = JulianDate::from_utc(Utc::now());
let mars = Mars::vsop87e(jd);
println!("{}", mars.position);
