# Astrex

**Astrex is an astronomy library written in Elixir**

provides functions to perfom typical astronomy calculations such as:
- coordinates conversion between equatorial and horizontal coordinates
- calculates the position of solar system objects (Moon and planets)
- calculates the magnetic declination to enable finding the "true north"
- includes a full blown NGC and IC objects database with query functionalities
