# Space Age

Given an age in seconds, calculate how old someone would be on:

   - Earth: orbital period 365.25 Earth days, or 31557600 seconds
   - Mercury: orbital period 0.2408467 Earth years
   - Venus: orbital period 0.61519726 Earth years
   - Mars: orbital period 1.8808158 Earth years
   - Jupiter: orbital period 11.862615 Earth years
   - Saturn: orbital period 29.447498 Earth years
   - Uranus: orbital period 84.016846 Earth years
   - Neptune: orbital period 164.79132 Earth years

So if you were told someone were 1,000,000,000 seconds old, you should
be able to say that they're 31 Earth-years old.

## Elm Installation

Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
installation and learning resources.

## Writing the Code

The first time you start an exercise, you'll need to ensure you have the
appropriate dependencies installed.

```bash
$ npm install
```

Execute the tests with:

```bash
$ npm test
```

Automatically run tests again when you save changes:

```bash
$ npm run watch
```

As you work your way through the test suite, be sure to remove the `skip <|`
calls from each test until you get them all passing!
