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 31.69 Earth-years old.

Writing the Code
The first time you start an exercise, you'll need to ensure you have the appropriate dependencies installed.
$ npm install
Execute the tests with:
$ npm test
Automatically run tests again when you save changes:
$ npm run watch
As you work your way through the test suite, be sure to remove the
calls from each test until you get them all passing!
