use-astronomy

Facade crate for primitive RustUse astronomy vocabulary.

use-astronomy re-exports focused crates for celestial bodies, stars, planets, moons, orbits, orbital elements, astronomical coordinates, magnitudes, epochs, constellations, observations, and catalog objects.

use-astronomy is not an orbital simulator, telescope-control system, ephemeris engine, astrophysics framework, sky-map renderer, observatory system, or astronomy database client. It describes astronomy concepts; it does not simulate, fetch, render, or control them.
