## Install via [npm](https://npmjs.com)

```sh

$ npm install lagrange-points

```

## Usage

```js

var Lagrange = require( 'lagrange-points' )

```

```js

// Masses is kg

var moon = 7.3477 * 1e22

var earth = 5.97219 * 1e24

// Distance in km

var distance = 384399

```

```js

var params = Lagrange.getParameters( earth, moon, distance )

```

Result:

```js

{

  distance: 384399,

  massRatio: 81.27972018454756,
