Javascript implementation of [Moshier's ephemeris](http://www.moshier.net) calculations for sun, planets, comets, asteroids and stars.
Initially written by [mivion](https://github.com/mivion/ephemeris), I converted it into a node module. I publish the module as a starting point for others, too. Pull requests welcome!
### Installation
`npm install ephemeris-node`
### Usage
*app.js*
```javascript
var ephemeris = require('ephemeris-moshier');
var result = ephemeris.getAllPlanets("10.08.2015 17:09:01", 10.0014, 53.5653, 0);
