Calculate Lagrangian libration points
npm install lagrange-points``sh`
$ npm install lagrange-points
`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:
